PROFORM 835QT Stops under load, then Restarts.
Treadmill runs with no load, stops with load. When it stops, the motor and walking belt stop.
I have already replaced the walking belt and lubed it. Not it.
The motor belt isn't tight or loose.
I have tested the motor flywheel with a foreign object with downward pressure and it stops, doesn't slow down.
I checked the motor brush and check for demagnetization, looks good.
Do I need a new motor or controller? uggh... Both are $200 for this machine.

You should have anywhere from 8vdc to 12vdc on those two wires.
If you have that voltage then the console is bad.
If you do not have the voltage then the motor controller is bad.
Sounds like I have a similar issue. I can try to measure this VDC. Shall I do it with the belt running or stopped?
There is a chance a breaker may have shorted open and not tripped. Please test these components individually and remember you want a closed circuit on all of them
