Replacement Parts for Fitness Exercise Equipment at SPORTSMITH This sounds like an issue with the console. It is almost like a software glitch in the programming. Before focusing on the console as the culprit, you can check the wiring leading up to the console for good continuity just to make sure the wiring isn't the issue. I will attach a link to a video on using a multimeter to assist in checking the wiring. Video about Multimeter Testing

Check all connections from power source in inside the cover where alternator is to upper display then if the problem still continues I suspect your upper console is going south. Call National Gym Supply @ 1-800-496-7278 they can either repair it or may have a exchange board for you.

My stairmaster has begun to squeak or chirp. It gets louder at higher resistance levels. Moving parts that I can see have been lubricated. Any ideas? Thanks!

Stairmaster pedal resistance electrical problem


How To Clean Commutator Using Commutator Stone Did you use a commutator stone when installing the new brushes? A commutator stone is used to remove carbon build up from the commutator of a motor or alternator, which is created from worn brushes. The commutator is the internal part of the motor or alternator that spins and makes contact with the motor or alternator brush. BE ADVISED: The dust created from cleaning the commutator is a carbon dust. Use caution when removing dust so as not to inhale. If servicing the motor or alternator without removing from the unit, be sure to disconnect power from the machine. To remove the carbon build up from the commutator, first remove the brush from the motor or alternator. Insert the commutator stone into the brushes place in the motor or alternator. Apply slight pressure against the commutator stone and by hand, slowly turn the motor or alternator shaft. As you are turning the shaft of the motor or alternator, the commutator stone cleans away the carbon that has built up on the commutator. Use a vacuum hose to suck out the dust debris or tip the motor/alternator over and allow the carbon dust to fall out. I am also attaching a video on how to install the brushes just for an extra reference. Stairmaster Alternator Brush Replacement Video

Then Be careful when inserting the brush have both sections go in simultaneous as you pulled out the old brush. Insert screws and connect the diode then test unit this should take of problem.
