Thank you for your question on the Pro-Form slowing down while you are walking on it. There could be a problem with the motor and motor controller but first I would suggest that you do the push and glide test on the belt.

Stand at the front of the belt right at the console and with both your hands push pretty firmly on the support rails to see how far you can coast down the walking board.

If you are able to glide on the belt 3/4 of the way down then the belt lubricant is not the problem.

A properly adjusted belt will have about 3 to 4 inches of lift in the middle of the belt on the sides when you pick up the belt.

Some belts require lubricant and others are lubed for life.

This does sound like a friction problem since you say it will work okay for awhile and then slow down.

Check the walking deck to make sure that it is clean and not sticky with foreign debris and belt material build-up.

You can clean the deck with mild soap and water and then dry the deck.

Please let me know what you find out on the push test and we can continue to troubleshoot with that information.

Hi Sam, I tried cleaning the deck, under the belt and did remove some debris. However the same problem persists. Could I need to re-apply lubricant? The model number is have is the J-8 831-297982 and the serial number K31140894. I think the belt tension is fine, about 3-4 inches up on each side and doesn't slip. What other recommendations do you have? If necessary, is there a service tech that can come and look at it? If so, what would something like that cost? I appreciate your help.

I am sending you a voltage diagram of your treadmill. If you are not completely comfortable making voltage checks please call and schedule a technician to diagnose and repair the treadmill. Since the console lights up your power to the treadmill is ok. The only way to tell where the problem is, is to check the voltage to the various components.

To make the voltage checks you need to put the treadmill in the calibration mode. To do this hold the speed up and stop keys in as you insert the key then let the keys go. The console should start lighting the different led's. Press the stop key twice and you will be in the speed and incline calibration. Run the speed up to 10 mph. Leave the console in this position while you make the voltage checks.

On the 8 wire harness on the back of the console use either black wire as ground and with the treadmill on and key still in between black and the blue pwm wire you should have around 1.5 volts dc. Make this test with the connector attached to the console.

If you don't have this voltage the console is bad. If you have the voltage go to the power board under the hood of the treadmill and check the same 2 wires for the same voltage. If you don't have the voltage here the harness between the console and power board is bad.

If you have the voltage going into the power board, go to the motor controller and check between the red and black and then the white and black. The voltages are on the images I sent. If you don't have these voltages the power board is bad. If you do have the voltages the motor controller is bad.
