proform 345s treadmill model # 831294030

A:

Thank you for your question.

I am sorry you are having a problem with the treadmill. To replace the power supply board first unplug the treadmill from the wall outlet. Then remove the motor cover. Then take a picture of the power supply with all the wires connect. This might come in handy later is you forget where the wires connect. Then remove the wires from the power supply. Now it is time to remove the board. You will see four mounts for the board. Use a pair of needle nose pliers to squeeze the plastic mounts. Once you have it squeezed, lift on the board to release it. Do this on all four mounts. Now that the old control is removed, install the new board by reversing the steps. After everything is connected, plug the treadmill in and check the operation.

If you are not completely sure the power supply board is the problem, I recommend following the diagnostic flow chart below. Just click on the image to enlarge it. Diagnosing the treadmill will require a voltmeter. Live voltage checks are dangerous, and possibly deadly. Exercise caution at all times. If you are not comfortable working with live electricity I suggest you call an experienced service technician. 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 on the treadmill.

Thank you for using Manage my life.

I recommend checking the DC voltage coming out of the power board to the console. First, locate the four-pin connector on the power board that has the red, black, green, and blue wires. With the treadmill plugged in, carefully check the DC voltage between the red and black wire. Make sure you leave the connector plugged onto the board. The connector should have small metal places to tough the meter leads on. You should get a reading of 8 to 12 volts. If you have this voltage, you need to remove the console and check the same wires on the console. If you do not have the voltage at the console, the harness has a break. If you have the voltage at the console, the console is defective. I hope this is helpful. Please let me know if you need further assistance.
