20 Most Recent KitchenAid KP2671 Professional 6 Series Stand Mixer - Page 7 Questions & Answers

Hi there,

Well first of all you can check the Hall effect sensor which determines the speed. this sensor cost is around $15.

Solution:
Please follow the below steps -

1. You'll need a phillips head screwdriver to open up the mixer.
2. Make sure that the connection between the control board and sensor is absolutely tight and snug.
3. Also, make sure that the orientation of the sensor connection between the control board and sensor is correct. it's hard to know which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or facing down. If, after you've made the connections, the mixer still doesn't work. Disconnect the sensor and reconnect it with the prongs facing the opposite direction and try it. 
4. Make sure you use common sense and unplug the mixer when making connections and such.
Please post comments for more help or information.......

Good Luck!!

Thanks

Merry Christmas BILLANDSHEIL! It sounds like you’ve already identified the problem and you just want to order the correct replacement part(s). I assume you’ve got a Parts List manual on hand, but if you're lacking one, you can download a PDF version from the KA website at: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case: KPM2671 and select from one of the files under Parts List (24). You’ll need to carefully check to make sure the manual you download matches your mixer model, because KA is notorious for providing differing part nos. for the same Illus. No. depending on the model and/or series version. After checking the 5 variations of Parts List manuals for your model, I found seven different part numbers based upon the control knob color selected. I think they make it confusing on purpose!
What ever Parts List manual you finally select, turn to pages 4 & 5 titled – Case, Gearing And Planetary Unit, and locate Illus No. 8, Control Assembly, and refer the part number for the knob color of your mixer. That is the part number you will need to use when reordering.
It’s not clear if you just want the speed selector knob or the whole knob control assembly. Unfortunately KA doesn’t just offer the knob, but only the whole PC board control assembly with knob.
As far as parts go, here are four potential online vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping. (As a check, you could also try to input the part no. you found and see if you get any ‘hits’ from the vendors above.)
Although you don’t need to get further inside your mixer to make this repair, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer that you might want to keep in your ‘toolbox’, should you have to delve inside your mixer in the future. The mixers displayed in the links may be different than your KA model, but the principles are the same.

• http://www.neilcrockett.com/mixer.htm
• http://www.foodonthefood.com/food_on_the_food/2009/04/how-to-repair-a-kitchenaid-mixer-yourself.html

Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able replace any part to your KA mixer.
Good luck and have fun. I hope this helps. Howard, Burke, VA

Hi BOBLUCAS820. From the symptoms you describe, I believe it is your Planetary/Agitator Shaft assembly that has fallen from the ‘head’ of your mixer. More than likely, the retaining pin or clip which secures the Agitator Shaft assembly to the Planetary has ‘sheared’ or broken, allowing the whole assembly to ‘fall’ out of the mixer head.
The good news is that this can be fixed quite easily (OK, maybe with a little effort) by yourself if you are a DITY type person, feel adventurous, and your mixer is not under warranty. However, before you start to disassemble your mixer, be sure you have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website: http://www.kitchenaid.com/flash.cmd?/#/page/home.
Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, KP2671, and select the last file, KP2671XWH3.pdf (325.07 KB), of the 24 listed under Parts List (24) (check to see it this matches your mixer model).
Turn to pages 4 & 5, titled “Case, Gearing and Planetary Unit”, which provides and exploded view for the disassembly and reassembly of your mixer, along with all the parts. I suspect your errant part is Illus No. 18, Retaining pin. There are two shown on page 4, and possibly Illus No. 25, Retaining Clip.
To gain access to these pieces will require removing the Transmission Housing (Illus No. 7), removing all the lubricating grease and removing the Illus No. 21, Bevel Gear. You’ll need a regular or Phillips screw driver, retaining clip pliers, and punch driver. When you remove the grease form the transmission cover and gears, be on the lookout for pieces of the Retaining Clip (Illus No. 25). The pieces of the sheared retaining pin should be found between the Bevel gear and the Worm Follower gear (Illus No. 19). With the transmission disassembled, you should be able to determine what parts need to be replaced and can order online.
You’ll need to replace the grease you removed with new grease. You should use a food-grade grease that you can order online (although I’ve seen automotive bearing grease used too – your call). Do not try to reuse any original grease as it may have ‘debris’ in it.
Here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com. You should search for ‘food grade grease’. Prices can vary widely between vendors, so do your comparison shopping.
It can be messy but quite gratifying to diagnose and repair your mixer yourself.

Between these three websites and their excellent pictures and descriptions and your Parts List manual, you should now be able to completely disassemble and reassemble your mixer, should you decide to go that route.
If you feel this repair is beyond your capability, then I would seek out a local small appliance repair shop in your area. KA Customer Care can give you names of local KA authorized repair shops in your area, but you can also do an online search to supplement what KA may provide you. Call to explain your circumstances and find out their hourly rate and get an estimate of what they think it would cost to repair your mixer. Also, always obtain three or more estimates – do some comparison shopping. I hope this helps. Howard, Burke, VA

There is a screw that turns about 180 degrees on the stand behind the bowl that fine-tunes the height of the paddle.

Yes, you can open it up and repair it yourself. Go to this website and look on the upper center of the page where you will see KitchenAid Repair Manual. You can download the file and view how to take the unit apart and repair any defective part. I suspect you have a short so check the power cord before taking the mixer apart. Try plugging it into another outlet to be sure the problem is actually the mixer. http://store.mendingshed.com/kitaidparts.html

Hi JEFF608, by the symptoms you’re describing, it sounds as if your mixer’s had a transmission failure; i.e. one (or more) of the gear teeth has failed and jamming the transmission, hence the lack of rotation in your planetary and the humming sound. I’m assuming when you say ‘humming’, that the hum is the sound of the motor trying to turn, but nothing (both the electric motor and agitator), is moving; is that the case?
The inspection and troubleshooting of your mixer’s transmission is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the correct Part List manual around when you start to disassemble your mixer. If you're lacking one, you can download it from the KA website (http://www.kitchenaid.com/flash.cmd?/#/page/home).
Click on Customer Care>Locate Manuals& Guides> and enter the 6 character model number, in your case KP2671, and select one of the files that appear under Parts List file. Turn to pages 4 & 5, titled ‘Case, Gearing & Planetary Unit, for the disassembly, troubleshooting, and reassembly of your mixer, along with all the parts.
You will have to remove the transmission gear case cover to access all the gears. Then you will have to remove all the grease to look for any gear that has failed.
While your mixer’s apart you should check for any other unseemly wear and tear on the gears, etc. You may find that it's just one particular gear that’s stripped. (The bevel gear Illus. No. 21, on my wife’s machine lost a tooth and jammed, but I was able to repair it quite easily under circumstances very similar to your mixer), or more gears that have failed.
Besides needing a replacement gear(s) and grease you might consider replacing the gasket, too. I recommend using a food-grade grease that you can order onlinn (although I’ve seen automotive bearing grease used too – your call).
Here are five potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com; and Grainger.com. You should search for ‘food grade grease’. Prices can vary widely between vendors, so do your comparison shopping.

Hi VBPROSANDY, When you say beater, I assume you mean your flat beater. Are you having the same problem with your Wire Whip beater and dough hook? If you are not, then the first thing I’d do is look inside the flat beater’s attachment well, to see that there is nothing; i.e. hardened food, dough or batter, in the bottom of it that would prevent the agitator shaft and groove pin from seating properly. The flat beater has two drain holes at the bottom for drainage, but if these get plugged it may prevent accumulated ‘gunk’ at the bottom from escaping, and over time the buildup may prevent the beater from seating properly.
If you find the beater attachment well is clean, then from the KA Instruction manual, to attach the flat beater...
1. Slide speed control to OFF and unplug.
2. Slip flat beater on beater shaft.
3. Turn beater to left, hooking beater over the pin on shaft.
Finally, check the groove pin on the agitator shaft to make sure it hasn’t become bent so that it doesn’t fit the beater properly. Pins shouldn’t bend, but sometimes they do.
The beater attachment process should not require any effort as the agitator shaft should easily fit into the beater’s attachment well and easily turn to the left. Your planetary should not move during this process and if it does move it will take some effort on your part to turn it. The fact that you’re turning the planetary means you’ve turned the beater as far to the left as it should go to ‘lock’ it. When you get this far, let go and the beater should fall into place on the groove pin.
Good luck. I hope this helps. Howard, Burke, VA

Hi, UIDA_2000, Sorry to hear about your gear issues. The inspection and troubleshooting of your mixer’s transmission is a DITY capability, particularly if your mixer is out of warranty.

Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number KP2671, and then select one of the files that appear under Parts List file. Turn to page 4, Case, Gearing and Planetary Assembly and locate Illus. #9, Hall Effect Sensor, part# 9703312. This is what you want to order.
Here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com, that should carry the KA parts. Prices can vary widely (between $4.00 ~ $9.00 plus S&H & tax) between vendors, so do your comparison shopping.

KLIMTJ1123 ? I?m sorry to hear about the grinding noise in your KA mixer. The grinding noise does not bode well for your mixer?s internal transmission. From the symptoms you describe, it sounds like one of the gears may be getting ready to fail. Your circumstances are very similar to my wife?s mixer (the same model and similar usage), but hers ?ground? to a halt in early October. Since it was out of warranty, I decided to troubleshoot and fix it myself. The inspection and troubleshooting of the inside of your mixer is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the Parts List manual on hand. If you're lacking one, you can download a PDF version from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case, KP2671, and select the first file of the 24 listed under Parts List (check to see it this matches your mixer model). Turn to pages 4 & 5, titled ?Case, Gearing and Planetary Unit?, which provides and exploded view for the disassembly and reassembly of your mixer, along with all the parts. As far as replacement parts go, here are four potential vendors in no particular order: RepairClinic.com; mendingshed.com; searspartsdirect.com; partstore.com. Prices for the same part can vary widely between vendors, so do your comparison shopping. Finally, here's a link to an excellent site that details the disassembly and replacement of a mixer's grease, which might be helpful, too. It?s a different model, but I found if very helpful, just the same: http://www.foodonthefood.com/food_on_the_food/2009/04/how-to-repair-a-kitchenaid-mixer-yourself.html After disassembling my wife?s mixer I found that a bevel gear tooth had broken and one right next to it was getting ready to break. I ordered a replacement bevel gear (actually two), a gasket and grease, and reassembled the mixer and now it works better than when we first unpacked it. Fixing your mixer yourself is much easier than shipping it off to a repair center, and you have the gratification of know that you did it yourself. I hope this helps!

BREZZZLIN – The inspection and troubleshooting of your mixer’s insides is a DITY capability, particularly if your mixer is out of warranty. Just be sure to have the correct Part List manual around when you start to disassemble your mixer. If you're lacking one, you can download it from the KA website. Click on Customer Care>Locate Manuals & Guides> Enter the 6 character model number, in your case: KPM2671 and select the appropriate file under Parts List and then check to see it this matches your mixer model. You’ll need Adobe Reader to be view/print the file.

Based on how you’ve described your mixer symptoms, I suspect there’s a problem in your controller assembly; particularly at the high (#10) setting. I'd start there and inspect the controller assembly first. It's possible a connection has become loose and only needs to be reseated. If your visual inspection yields nothing, then its probably the somewhere in side the controller assembly. Unfortunately the whole controller assembly is on a little PC board filled with resistors, capacitors and diodes, and was not meant to be 'home fixed'. My 'expertise' ends at being able to recognize a resistor from a capacitor, but I don't get much deeper than that. A local small appliance repair shop should be able to determine if the controller assembly is functioning properly or not.

Good luck, I hope this helps! Howard – Burke, VA

Hi. Stop using your mixer. If your mixer is still covered by warranty, call Kitchenaid Customer Service, they are very good with warranty repairs.

If your mixer is out of warranty, remove the silver band that surrounds the top of mixer. Remove the top cover. At the front of the mixer, locate the transmission housing which is now exposed. Examine this housing carefully for cracks. If you find cracks anywhere in this housing, you have found the under-engineered plastic transmission housing. Kitchenaid's replacement housing is made of metal. Your plastic housing has no business being in a mixer that is marketed as being able to mix bread dough. It cannot!

If you're confident that you can make the repairs yourself, go to the Kitchenaid website and download the parts drawings. Remove the Trans. housing, remove the worm gear shaft assembly which is driven by the motor.. Remove and save as much grease as necessary to thoroughly inspect the worm gear. Inspect the worm shaft bearings. Look for cracks, or missing pieces on the bearings. Look for crunched cogs on all gears. Be prepared to wait at least a month for your parts to arrive after you order them. The replacement grease should be Shell Darina 2, or Chevron FM ALC EP 2.

If you're not confident about repairing this yourself, call Kitchenaid and determine the nearest "approved" repair shop.

You may be able to pressure Kitchenaid to pay for the damaged parts in your mixer. They are still installing these plastic Trans. housing on new mixers. Insist on a metal cover when replacing. Apparently, Kitchenaid feels no shame in their manufacturing process, and will not issue a recall notice for these housings. They are substandard at best.

The planetary gear is part of an assembly that includes the washer, fiber washer, pinion gear, retainer clip, agitator shaft and the retaining pin. I am assuming that it was the whole planetary gear assembly that fell out. Since I'm not sure exactly what caused this to happen I am unable to give you a solution to prevent this again unless you can provide more details on anything else that may have came out. I can provide you with a diagram for your mixer.

If not please let me know and add anything more specific about this.
I hope this helps.

it could be the bushings
but i would suspect the plastic gears

Your Use and Care Guide will cover proper assembly as far as the external parts of the mixer. If you are in need of a Use and Care Guide, Kitchenaid Customer Service will send you another at no cost.

You may contact them at your toll-free telephone number: 1-800-541-6390.

If you are referring to an internal breakdown / insruction manual for the mixer, this may be found in great detail online at mendingshed.com.

All Kitchenaid manuals are available online at www.kitchenaid.com.

On the main page, click Customer Care in the upper-right hand corner. Then click Locate Manuals and Guides.

You will want to enter your model number exactly as it appears on the bottom of the unit. You will need to tilt the mixer gently onto its side and locate a white sticker to see this.

When entered on the website, this will pull up the Use and Care Guide (manual) and even exploded parts views if those are needed.

A clicking noise is not indicative of a major motor issue with a Kitchenaid stand mixer. If the noise worsens or is accompanied with other symptoms, or if you are incredibly concerned with the development of clicking, I would suggest contacting Kitchenaid Customer Service.

Their toll-free telephone number is 1-800-541-6390.

Remove the silver band, remove the top cover. At the top front of the mixer locate the transmission housing. If it's plastic, inspect it carefully for cracks around the screws and the body of this housing. If you find cracks, you have found the cheap plastic part that kitchenaid still installs in new mixers, and the cause of your trouble. They know that it's substandard but don't care enough to place a recall notice on this part. It may not please you to know that their replacement part is METAL like the original part should have been. "For the way it's made"! Indeed!

If you intend to repair the mixer yourself, go to kitchenaid's website, enter your model # and locate the parts list for your mixer. Download the drawings, they will assist you with your project
