This is a common smell when using these units. The smell comes from the ceramic load resistor. This part of the unit heats up as you use it. All it takes is a little bit of dust on the resistor and when it heats up, you get the burning smell. Replacement Parts for Fitness Exercise Equipment at SPORTSMITH

This video covers general resistance troubleshooting for the Stairmaster 4400CL, 4600CL, and SC916 Steppers.
Tools Needed: Multi Meter, Jumper Wire
Resistance problems could be either mechanical or electrical in nature.
Mechanical problems are easily identified by noise. If a grinding noise is heard while pedaling, this is an indicator the drive hub assembly is having a problem. If a ratcheting sound is heard while pedaling, this is an indicator of a loose belt or a belt that could be coming off.
Once you've eliminated the possible mechanical causes for resistance problems, then it is time to investigate the electrical system.
The easiest test of the electrical system when investigating a resistance problem is to step onto the pedals and access Diagnostics. This is done by pressing Level ^, 6, ENTER. (DIAGNOSTICS will appear in the upper display window.) Press Level Down twice to get to the alternator test. (ALT TEST will appear in the upper display window.) Press ENTER to begin the test. As the video shows, resistance drops out when the test begins. So, if this occurs, press the Level ^ one time. This will turn the field ON. This verifies that voltage is passing from the display through the display cable to the lower control board. This confirms there is good communication between the console and the lower control board and that the voltage is being supplied to the alternator. If resistance is lost during this portion of the test, inspecting the cable should be the first step of action. Look for bent pins, loose connection or crimped wire.
Other components of the electrical system to inspect for resistance problems are the battery, load resistor, speed sensor and alternator.
We'll discuss the battery first. In order to get a proper reading, testing the battery should be done with the pedals in motion. There are 3 different battery readings a person may encounter. A reading of 6 VDC or greater indicates a good battery. A reading below 6 VDC but higher than 4.8 VDC indicates the battery needs charged for 24 hours. A reading below 4.8 VDC indicates your battery is bad and needs replaced. For more information, watch our battery testing video.
If your battery is good, the next item to check is the speed sensor. The speed sensor should be spaced a business card thickness away from the speed disc. If the speed sensor is spaced properly, the function of the speed sensor can be verified by confirming that proper voltage is present. For more speed sensor troubleshooting, watch our video on speed sensor testing and adjustment.
Next to inspect is the load resistor. Load resistor testing is pretty simple. Load resistors are ohm rated, and you want to verify the proper ohms for the load resistor being tested. Load resistors can cause the resistance to come and go. This means you may pedal a few steps and then the pedals will drop or loose resistance. Then, as the load resistor cools down a bit, you may get resistance again for a few steps. If the resistance goes back and forth like this, the load resistor likely needs replaced. For more information, see our load resistor testing video.
The last electrical component to inspect when investigating a resistance problem is the alternator. The alternator can be easily tested by performing the B+ to Field jumper test. For details on how to perform this test, watch our alternator testing video.

Display reads CONFIG RQRD or NTM CONFIG RQD on Stairmaster Equipment
Probable Cause
The message CONFIG RQRD or NTM CONFIG RQD appears when the console needs to be configured for the machine type it is installed. This message is common when the console has been replaced or if the settings have been changed. Message is commonly seen on various Stairmaster equipment such as bike models 3000CE, 3300CE, 3400CE, 3600RC, 3800RC and 3900RC; stepper models 4400PT, 4600PT, 4400CL, 4600CL and SC916; stepmill models 7000PT and SM916; elliptical model ClubStride 5100.
Corrective Action
Make sure the unit is in an "idle" state. "Idle" state means the console is not displaying an error or any message that requires data input. The display should basically be freshly powered up, scrolling the EKG or welcome message
Configure the console for the proper machine type by pressing Level UP, 80, ENTER
Using the Level UP or Level DOWN keys, scroll through to the proper machine type (Bike, Elliptical, Stairclimber or Stepmill)
Once the proper machine type is shown on the display select the machine type by pressing ENTER
This completes the steps necessary when your Stairmasterdisplay readsCONFIG RQRD or NTM CONFIG RQD

Your transmission chain and reduction pulley, and or step chain need to be checked.
It could just be the transmission chain is on just a little too tight, causing the creaking or that the step chain/s just need a little grease on them (which is likely the culprit to any creaking).
If you find you need need any further assistance we would be happy to help you out :) by chat at www.sportsmith.net or by phone at 888-713-2880
We look forward to hearing from you if you need us!
Chances are all you are missing is that you need to set that console to the correct machine type and to do so you will need to hit the following keys.
Level, UP, 90, and Enter and just scroll until you find stepper and hit enter.
If that does not solve the issue, it is definitely something more substantial and we would be happy to help you out :) by chat at www.sportsmith.net or by phone at 888-713-2880
We look forward to hearing from you!
The battery charger is only used to recharge a low battery.
If the console does not light up after pedaling. connect the battery charger to the machine and then plug it into an electrical outlet.
If the console powers up, your battery is low and needs to be charged.
Leave the battery charger connected to the machine for 24 to 48 hours to charge the battery.
It is okay though to use the machine with the battery charger connected.
If that still does not work, check over all main cables for loose connections or fraying. Especially those to the battery and to the console.
Verify that the speed sensor is 2mm (about a credit cards thickeness) from the speed disc on the alternator.
Please be sure to disconnect battery cables before adjusting speed sensor or touching any other electrical components.
If anything else comes up we would be happy to assist you, contact our Tech Support Team at 888-713-2880 or visit us online at

Sorry to hear you're having issues with your machine, there are a couple of tests you can run to figure out whats going on
1: You want to make sure your battery is in good condition, by using a MultiMeter to check voltage and make sure it is outputting about 6V (If you have a PT, you want to start by just checking if your power supply is connected firmly into the machine, or check for any damage.)
2: Run an outlet test by just switching the power cord to another outlet. This is to make sure that the outlet is in working condition.
3: Visually inspect the machine for any crimped, loose, or disconnected cables.
4: After checking battery voltage or outlet voltage, you'll want to follow that power through out the machine by running a DC voltage test on both your power supply (PT) and MCB (on a CL)
5: Check for continuity through your main cable going to the console.
If any of these steps do not work or you would just like further detail please do not hesitate to call us or visit us online. We are always hear to help.

First disconnect the grey cable from the back of the console and UNPLUG YOUR MACHINE from the wall.
If your cable has a 6-pin round connector, you will need to check pin sockets #5 (black wire), #3 (blue wire), #2 (brown wire) and #4 (white wire) with your ohmmeter for continuity in each pin. Should get continuity from all if cable is good.
If your cable is a 9-pin cable, you will need to check pin sockets #5 (blue wire), #3 (black wire), #2 (brown wire) and #4 (white wire) with your ohmmeter for continuity in each pin. Should get continuity from all if cable is good.

Stairmaster Stepper 4000PT Alternator Belt Replacement WARNING: The belts must be properly tensioned. A belt that is too loose will cause slow and sluggish operation. A belt that is too tight will cause excessive noise and belt wear.
Remove side covers.
Loosen the adjustment screw that mounts the alternator to the alternator brace and the pivot adjusting bolt that mounts the alternator to the frame.
Pivot the alternator down and remove the belt.
Make sure the is centered on the pulleys during installation.
Pivot the alternator up or down as necessary to allow 1/4" (0.6 cm) of belt deflection with fingertop pressure at the midpoint between the two pulleys.
Tighten the alternator adjustment bolt. Verify 1/4" (0.6) deflection in the belt.
Preform this test if you are having trouble entering data into the console. If you cannot enter the DIAGNOSTIC code due to an inoperable keypad, replace the console.
Press [2] to start the test.
The display LEDs will light up in an L-shaped formation, representing the keypad matrix. Pressing a button on either the exercise program keypad or the function keypad will light an LED within the outline on the display that corresponds to that button's position on the console.
Firmly press each button. If the LED corresponding to the button you pushed does not light up, the keypad is bad and the console should be replaced.
Press [CLEAR] to test the LED and then end the test 10 seconds later.
Unhook the pedal arm return spring from the spring hanger.
Remove the snap ring from th pulley shaft. WARNING: To reduce the risk of eye injury, wear eye protection when removing snap rings.
Slide pulley and washer off the shaft.
Before reinstalling the pulley, clean the pulley shaft thoroughly with a clean, dry cloth. Apply a thin coat of multipurpose grease to the pulley shaft.
Slide the pulley and washer onto the shaft. Install the snap ring.
Route the spring under the spring pulley.
Hook the end of the spring over the spring hanger. WARNING: Do not twist the spring during installation. It will wear excessively and reduce the life of the spring.
Reinstall the drive chain, ensuring the master link is properly installed.
Check the drive chain tension. There should be a total of 1" to 1-1/2" (2.5 to 4.0 cm) of play, up and down, at the slackest point in the chain. If the drive chain tension needs adjustment, refer to the "Drive Hub Assembly" section.
WARNING: If the drive chain is too tight, the drive train will wear excessively, shortening the life of the drive hub assembly. If the chain is too loose, the machine will be noisy and will operate at less than peak efficiency.
Lubricate the chain with 30W motor oil and wipe off the excess.
The following test will help to determine if the cause of no resistance on your Stairmaster 4000PT stepper is the console. By performing the following test, the console is eliminated from the electrical circuit. If resistance is present when the test is performed, the console is bad. Paper Clip Trick
First UNPLUG YOUR MACHINE from the wall, then disconnect the grey cable from the back of the console.
If your cable is a 6-pin round connector or a 9-pin square connector, using a paper clip formed into a "U" shape, insert the ends of the paper clip in the pin sockets #2 and #4. Then you will need to plug the power cord back in and start stepping. You should experience full pedal resistance.
If there is still no pedal resistance, UNPLUG YOUR MACHINE from the wall and disconnect the wire from an end of the load resistor so that there is no wire attached to that end. Then plug the power cord back in and perform the paper clip test again. If resistance is present, the load resistor needs replaced. If resistance is not present, either the gray cable or the alternator is bad.
Unhook the pedal arm return spring from the spring hanger.
Detach the spring from the step chain by removing the master link. The spring-chain connector is in good condition if it has an hour glass shape. Replace a worn spring-chain connector.
Check to ensure that the spring pulley turns freely and is not worn excessively. Refer to the "Spring Pulley" section if you have to replace the pulley.
To reinstall th spring, connect it to the end of the step chain using the master link.
Route the spring under the spring pulley.
Hook the end of the pedal arm return spring onto the spring hanger. WARNING: Do not twist the spring during installation. It will wear excessively and reduce the life of the spring.
