Question and Answers

Q:

treamill 760 ekg

A:

Thank you for your question on the treadmill not running.

There is a test we can do to determine if the walking belt is the problem or the motor and controller are the problem.

First check to make sure the walking belt is in good condition and has adequate lubricant on the underside of the belt to reduce friction and stress on the motor.

If you have a volt/ohm meter we can check the drive motor to determine its condition.

Remove power to the treadmill and remove the hood. Locate the black and red wire going to the motor and disconnect.

Set the volt/ohm meter to DC volts and put the black and red probes from the meter into the black and red motor wires.

Then plug the treadmill back in and turn the treadmill on and by push walking the on the belt to get up to 3 miles per hr that will show on the display and the motor will need to show at least 27 volts DC on the meter to be good.

If you do not get 27 volts DC then I would suggest replacing both the motor and the motor controller.

Please let me know what you have found out and we can continue to troubleshoot with that information.

Q:

Profit 760 EKG going too fast

A:

Thank you for your question. 

I am sorry you are having a problem with the treadmill. If the unit races as soon as you plug it in I suspect the motor control board is shorted. To verify this you need to unplug the treadmill and remove the hood. Then locate the motor control. The image below shows what the control looks link. Once you find the motor control, make note of where the small red, white, and black wires are connected and remove them. Then plug the treadmill in and see if it takes off. If it does, I recommend replacing the motor control board. The parts for the treadmill can be ordered from the following link.  Parts for treadmill model 760 EKG.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a  Sears technician.  Here is a link for the website:  Sears Home Services.  I hope this is helpful. Please let me know if you need further assistance.  Thank you for using Manage my life.  Mark T.

Q:

The belt on my Proform 760 treadmill won't turn. All else seems ok. What to do?

A:

When the treadmill motor doesn't start it can be caused by the motor, controller, power board, console, or a wiring harness. I am sending you a wiring schematic for your treadmill, and instructions for putting the treadmill into the calibration mode. To test the voltages to and from the console and boards the treadmill has to be in calibration. Don't stand on the walking belt because you might move a wire causing the treadmill to start turning. The console will beep while it is in calibration, let it beep, it won't damage it. Read the voltage to the console between the red and either black wire, it has to read between 8-12 volts dc. Between either black and the blue wire you should read 1-5 volts dc. If you don't have the 8-12 volts between black and red, the power supply board is bad. If you have the 8-12 volts and not the 1-5 between blue and black the console is bad. If you have the voltage coming from and going into the console remove the hood covering the motor and front roller of the treadmill and read between black and blue at the connector going into the power board. It should be 1-5 just as it was at the console. If you don't have this voltage the wire harness between the power board and the console is bad. If you have the correct voltage at blue and black coming into the power supply board go to the motor controller board and check the voltage at L, W, and H on the controller. If you have the voltage between L and H but not between W and L the power supply board is bad. If you don't have voltage between L and H the controller is bad.
