Question about KitchenAid Food Mixers
My new kitchen aid HD professional mixer on speed 1 starts slow increases to speed 10 then cuts out. High speeds nothing but a hum and occasion the same as above. When i start it up again on stir (speed 1) it repeats itself slow first then speeds up then cuts out.
You need a new speed control board, easy fix about $35.00 for the part and an hour of your time, not even messy to do a total of six screws and four wire connections that clip on, several youtube step by step instruction videos available. parts available on ebay. let us know if this helps you

I would recommend that you first check the Hall effect sensor which determines the speed. I had this exact problem and I actually went out and bought another Hall sensor for about $13. I replaced the original sensor and made sure that the connection between the sensor and control board was nice and snug. My blender worked as good as new! But I was curious to know if my original sensor was defective so I put it back in mixer and again made sure all of the connections were tight. Guess what? My original sensor also made my mixer work! There was nothing wrong with my original Hall effect sensor except the connection between the control board and sensor was not adequate--unfortunately I didn't check the connections before I decided to buy another one. My guess is that the connection between the control board and the sensor probably loosens or comes undone over time from use and vibrations.
1. Download the mixer parts and diagrams from the Kitchenaid website to see what the Hall effect sensor looks like. 2. You'll need a phillips head screwdriver to open up the mixer. 3. Make sure that the connection between the control board and sensor is absolutely tight and snug. 4. 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. I actually found the right orientation through trial and error. By going through this trial and error, I also had my Eureka moment when I realized that the original sensor probably would also work if it were reconnected with correct orientation. 5. This whole process probably takes less than 10-15 minutes to perform. 6. Make sure you use common sense and unplug the mixer when making connections and such.

I would recommend that you first check the Hall Effect sensor
which determines the mixer’s speed. I had this exact problem and I
actually went out and bought another Hall sensor for about $13. I
replaced the original sensor and made sure that the connection between the
sensor and control board was nice and snug. My mixer worked as good as new! But
I was curious to know if my original sensor was defective, so I put it back in
mixer and again made sure all of the connections were snug and tight. Guess what?
My original sensor also made my mixer work! There was nothing wrong
with the original Hall Effect sensor except that the connection between the control
board and sensor was not tight--unfortunately I didn't check the connection
before I decided to buy another sensor. My guess is that the connection between
the control board and the sensor probably loosens or comes undone over time
from use and vibrations. To fix your problem:
1. Download the mixer parts and diagrams from the Kitchenaid website to see what the Hall Effect sensor looks like. BTW the part number is 9703312.
2. You'll need a phillips head screwdriver to open up the mixer gear case cover.
3. Make sure that the connection between the control board and sensor is absolutely tight and snug.
4. Also, make sure that the orientation of the sensor is correct. It's difficult to tell which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or down. After you've made the connection, run the mixer. If it still doesn't work, disconnect the sensor, reconnect it with the prongs facing the opposite direction and try it again. I actually found the right sensor orientation through a little trial and error. But by going through this trial and error, I also had my Eureka moment when I realized that the original sensor probably would also work if it were reconnected with correct orientation.
5. This whole process probably takes about 10-15 minutes to perform.
6. Finally, use your common sense and make sure to unplug the mixer before checking, connecting or disconnecting anything.

It shouldn't do that, and I really doubt there's anything you can do about it other than to have the defective part replaced. It sounds to me as though there's a problem with the control mechanism. If the machine is still under warranty, contact Kitchenaid to see about getting it repaired or replaced. If not, get the name of a local shop that repairs Kitchenaid mixers -- from your description of the problem, the mixer is nearly unless in its current state.

Hi REDLACQUER. Sorry to hear about the metal shavings. This is probably not to best way to take iron in your diet... My first thought would be to ask if your mixer is still under warranty. If you’ve had the machine less than one year, then I’d let KA replace your mixer with a new one. However, I suspect like many who seek assistance from FIXYA.com, your mixer is out of warranty, so what can you do?
Have you been able to find exactly where the metal shavings are originating? From the symptoms you describe, it appears that the planetary/agitator shaft assembly may be rubbing against its housing and generating the metal shavings at higher speeds. Have you noticed any increased noise levels/squeaking/screeching when the planetary rotates? It’s also possible that the planetary is out of alignment and not rotating true. Could the agitator shaft been jarred or hit hard during set up or moving in or out of you storage cabinet? Or the shavings could be symptomatic of other internal gear problems, but that would be the least likely scenario as the mixers internal gears are pretty much self-contained.
The good news is that this can be troubleshot and fixed quite easily (OK, maybe with a little effort) by yourself if you are a DITY type person, and feel adventurous. 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 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, KP2671, and select the last file, KP2671XWH3.pdf (325.07 KB) listed under Parts List (24) (check to verify that it 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 Planetary Assembly, Illus No. 15, is rubbing somewhere against its housing, Lower Gearcase, Illus. No. 24.
To gain access to these pieces you’ll need the following tools: a regular or Phillips screw driver, retaining clip pliers, and a small drift pin punch and a small hammer. You need to remove the Transmission Housing (Illus No. 7) and remove all the lubricating grease from the transmission housing and gears (when removing the grease be on the lookout for shavings in the grease which would indicate excessive gear wear). This will allow you to remove Illus No. 25, 21, 18 & 19, Retaining Clip, Bevel Gear, Retaining Pin and Worm Gear Follower, respectively.
Once you remove the Retaining Pin (Illus. No. 18) the Planetary Assembly can be tapped down through the Lower Gearcase Assembly (Illus. No 24). With the Planetary removed, you can inspect it and the inside of the Lower Gearcase to determine where the shavings originated. Be sure to look closely at the Planetary Gear in the lower gearcase as well as the Agitator Shaft Pinion Gear (Illus. No. 12). That will also identify what parts need to be replaced, which you 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 (for grease). 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.
Finally, here are some links to several excellent websites that detail the disassembling/reassembly of a KA Mixer. The mixers displayed in the links are different KA models, but the principles are the same.
I hope this helps. Howard, Burke, VA
