Proform 525 CT Motor not working

in Treadmill Problems
Proform 525CT PFTL49617.0 motor stop working after giving burning smell for while.
Tested motor by giving 18v DC ,but does not rotate.
Also checked the output voltage at motor controller for A+ and A- is 167 v DC and red led on board starts blinking after pressing start and solid red on stop.
Not sure what is bad , id it motor or control board or what.
Incline motor and console works perfectly

    Was planning to order replacement motor but than thought if 167v DC can blew new motor also
  • rajnprajnp
    Resistance between + and - of motor is also infinite and its not 5 to 10 ohms

    if the motor won't spin with a battery, then I'd replace the motor. Here is a code you can use on the checkout page for a 5% discount (5offkevin)

    But what for 167v dc from controller to motor, this can damage the new motor also? or this high voltage at A+ and A- are normal
  • KevinCKevinC
    was the motor hooked up when you tested the controller voltage?
  • rajnprajnp
    no motor was disconnected
  • rajnprajnp
    I tested with both motor connected and disconnected, both time it was same DC 167volt
  • rajnprajnp
    I replaced the mosfet on controller also still same numbers
  • KevinCKevinC
    it's likely you have more than 1 issue here
  • rajnprajnp
    Should I replace the motor or not at this point. or both motor and controller
    How much the DC voltage should be at A+ and A- on controller with motor connected and motor disconnected
  • KevinCKevinC
    I would replace the motor first since it's know to not work from a battery. Then, the controller if it still doesn't work. The controllers output varies from about 15VDC @ .5 mph up to about 90+ or more at full speed with the motor connected. I've found that the output readings with the motor disconnected can vary a lot.

    I took out old motor from treadmill but I can not remove flywheel from it as it is very hard to remove.I will need this flywheel if I get motor from you.
    How to remove flywheel.. I have tried so much but no luck
  • KevinCKevinC
    here is a video on how to remove the flywheel

    I ordered the motor from you and got it, but now problem is I can not put back the drive belt on pulley.
    I have not fully tighten the motor bolts yet but still can not put back belt on both pulley
  • KevinCKevinC
    you may have to loosen the walking belt up and let the left side of the front roller move forward in order to get this belt back in place.
