Question about Exercise & Fitness

1 Answer

I have a proform 625 treadmill that slows or stops after 1 minute. I did what was suggested and cleaned the speed sensor and even adjusted it closer to the pulley. The motor also still hums when it stops. If I get off of it then it usually picks back up for a minute. Maybe bad speed sensor?

This hapeen because the system has protection itself, to due the lack of maintenance, by that reason you must LUBE the deck belt, maybe you have a WORN deck belt.
2) LUBE the rollers bearing too
3) Test the drive belt motor for cracking or worn belt.
4) Test the input voltage motor, if there are the motor need replace
5) Test the output voltage board, for input voltage motor, if there are NOT the board is faulty.

SOURCE: proform treadmill 580si motor is not working

Recheck your wiring and check your ground. If all that checks out then triple check your control board. Also the motor SHOULD have a reset button make sure that the button is not out and it is fully pushed in

If I understand correct, the treadmill will not run correct unless you have the safety key in. Well yes this is correct because once the safety key is removed the treadmill will stop. If your treadmill is running extremely fast just by turning it on, you may need a new speed sensor. www.AtlantaFitnessRepair.com

SOURCE: Treadmill will not maintain the correct speed.

your belt may not be tight enough and it is slipping which can cause it to move faster than the motor

SOURCE: Proform 622 Exp treadmill belt slips

If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 2 to 3 inches above the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened. Now if this does not solve this problem then check the drive belt and adjust accordingly, also reverse the process of the above mentioned

Can I dismantle proform 360p to move it


When plugging my treadmill in it was going at max speed without the key even in. Now it has slowed to a complete stop and I can not get it to move. The incline works, but not the speed.

Treadmil stops or slows down upon walking.


Check both belts to be sure they are adjusted and not slipping.Check the underside of the walk belt to see if it feels frayed in the center as compared to the edges, the center always wears more than the edges a really worn belt must be replaced. if it is nor worn there is a wax lubricant for proform treadmills that can be purchased at retail stores that sell treadmills.Sears, dicks sporting goods and also treadmilldoctor.com are good places to buy it.

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.
