Question about Proform C950 Treadmill Walking Belt

1 Answer

Proform C950 intermittently stops working shortly after start

Most occasions that I try to use my Proform C950 it stops within the first minute. The display remains active, but the belt stops moving and won't start again until I hit Stop or pull and re-insert the key. I bought the treadmill used and it worked well for the first several months. Then it would occasionally stop when I was at a full run and gradually got worse to the point that it stops almost immediately after starting a slow walk. It does seem run well with no one on it. I have seen several online sources indicating that I should use a silicone spray on the belt, but the manual specifically states that I should not do that.

Testimonial: "Thanks for your answer. The video that you posted is for lubing the belt, not the roller bearings as you suggested. I have new information. The treadmill will now stop shortly after start even with no one on the belt. I took off the cover to observe the troubleshooting LEDs on the control boards. The motor control board 15V LED is lit indicating it is receiving power. The SPD SIG LED blinks rapidly, when I command the treadmill to start from the console, indicating the signal is received. The GATE LED lights up proportionally to treadmill speed, but then goes dark when the treadmill stops."

Sometimes the tread needs to be lubricated. This was the case with ours. You can get a lubrication kit at ****'s Sporting Goods or other larger sport stores and it will instruct you on how to do it.

Most likely a bad drive belt. Take the cover off the motor area. If you see black dust near the left side of the motor, replace the drive belt.

You have to put the safety key in if you want to select speed/incline or predefined programs.
It starts and runs at full speed on that occasion because it's part of the maintenance process, that lubricates the inner rollers so that it will continue to work perfectly for as long as possible.

Proform 740CS runs okay but the incline does not


ProForm Treadmills have a reset procedure for the incline function. With the key inserted in the console, activate the incline; while the incline is changing, remove the key. Wait 30 seconds, then replace the key. The incline should to maximum, then to minimum, resetting its limits. It worked for mine just 10 minutes ago; the procedure is in the manual if you have it. Good luck!

Treadmill stops running


I had simillar problem. I have proform 830 QT. My trademill stops after 10 minutes of work out. Everything shuts down and the circuit breaker pops out.

Root cause:- no lubrication under walking belt. Caused the moter to over work (over heat) and hence te circuit breaker popped out to prevent blowing of motor.

Solution:- Apply the lubricant under walking belt and adjust the belt tension if needed.

Back ground:- Contact proform customer service at 1-888-533-1333 (http://www.iconservice.com/proform/faq_tread.html) and buy the treadmil cleaning kit or lubricant kit which comes with a wand for easy application. It may cost you 35 dollars including shipping. If you need to fix your treadmil right away, use NAPA silicon spray 8300. Proform actually tells do not use it as it may damage your belt. However the specialst who came to fix my treadmill just sprayed it and collected 100 dollars. When I called proform they told me lubricating will fix it and its my mistake to not trust them. I guess they knew exactly what they were saying.
