Question about Proform 790T Treadmill

Open Question

Hello I have a Pro Form 790t. It turns on ok but when I hit the start button the belt does not move. I've had an electrician check it and everything is ok. Someone mentioned about lubricating it but I don't know how or if this is the problem. Please can you help? Many thanks Karen

SOURCE: Pro-Form 360P, when I step on the belt, it stops

when the belt is stopped you should be check the deck if this it´s worm or the walking belt, because a probable cause is lack of lubrication, In addition should send the engine to revision, because according to what your gross probably already there are some Diode Rectifier damaged, You must know that the cause that generates this problem stems from the walking belt and the table or deck

Check out The treadmill Doc. Fantastic site and great people to do business with. A lot of helpful trouble shooting information for free! I'm betting it is the motor control board. Site will lead you through step by step instructions to check and fix it yourself. I saved a ton of money and with a little know how and good information you can too.

SOURCE: I have a noisy Pro-Form Model 285T treadmill

Hey Richard Depending on the noise it could be one of several components failing. If loud clanking or clunking noises these components are Drive Motor, Front or Rear Rollers.
If it is a loud humming noise increasing and decreasing when planting yours feet then it is either the Inductor ( square object ) or the internal windings of the Drive Motor.
Unplug your unit remove the motor shroud with a long shaft flat tip screw driver you'll be able to pin point the problem with this tool.
Now locate front shaft and rear roller tension adjusting bolt ( refer to owners Manual) plug in unit, start unit and touch flat tip on the shaft and place your ear on the handle the noise will be amplified and you will be able to locate the noise repeat this procedure on the other above mentioned components if problem is not found. GOOD LUCK!

My pro form treadmill - panel lights come on but belt not operating? Any ideas how to repair or who would call out - Derbyshire area? Thanks

If the light are on and when pushing the console start button the oval track lights (on the console) should move. If not, then your console is bad. On most Pro Form consoles you have to replace the entire console. Individual parts are not available.

Lights work and unit clicks when u hit the start button but the motor will not run. checked thermal fuse and it checked out to be ok.

it may have a belt switch(check belt) or you have lint in the motor switch and the switch lever can't move compressed air works best to clean it

Monitor will not turn on

My LG L19534H (analog) flat panel monitor began doing this too after two years of good performance in a Windows XP Pro environment. Here is my crude "fix": right-click desktop, hit Properties, select Screen Saver tab, hit Power button, and choose "Never" from the drop down lists for Monitor and System Standby. Hit OK to save changes.'re right...what if you need standby, etc. Don't know if it's video card starting to fail or not. Time will tell. Hope this helps for now.
