Question and Answers


Why is my Proform XP 420 Razor elliptical exerciser stuck at high resistance?


You could have a failed resistance motor (part 241949) or a failed console (part 252257). A wiring failure or a mechanical failure could also cause this problem. The first image below shows how to access and adjust the resistance belt. If you check the resistance belt and it is okay, you can check the console and resistance motor using the technical information in the second image. Check the wiring connections between the console and the resistance motor.

You can view a parts list diagram and order parts for this exerciser on the Sears PartsDirect website. Use your full model number (831.237431) to access the parts for your exerciser.

This information should help you determine the cause of this failure. If you need more help, resubmit your question with additional details.

Lyle W, You are awesome. This is exactly the information I needed. After a few months without use, my unit was also stuck in high resistance (even though the display could be changed to low). Ultimately all I needed to do, was push downward on the "resistance head" (for lack of a better name), at the rear of the flywheel. The diagnostic mode described in Lyle's second attachment has much better control over the resistance motor. I was able to run the motor to higher and lower settings than what is normally availible. In combination with pushing down on the "resistance head", this seamed to completely free it up, and it is now functioning like new again. No adjustments necessary. I am so excited. Thank you Lyle!!!
