Either your Motor or Motor Control Board(MCB) is faulty.
Try testing your Motor with a Drill Battery:
1. Disconnect the machine's power lead from the power socket, so that there is no power to the machine.
2. Open the Motor Hood.
3. Disconnect the Motor + and - leads from the Motor Control Board.
4. Connect + and - leads(normally Red and Black) to the Drill Battery.
The Motor should turn the Belt.
With the Motor leads disconnected from the MCB, you can connect the machine to the power, Press Start, and if this trips your Fuse Box you know its definitely the MCB.
Only carry out these tests if you are competent.
Lethal Voltages are present.

Check to see that the treadmill does not draw more amp than stated in the owners manual. If you are, then the problem is in treadmill. If not try another circuit in the house (not just another receptacle).

Proform xp 580 trips the breaker as soon as you turn it on

Treadmills have up to a 15 amp power draw. They are like space heaters, Proform often recommends having a dedicated 15-20 amp circuit for a treadmill. Ellipticals have less power draw.
I repair most Icon products, is this a new problem with an old treadmill? If it is a new treadmill, call the number in the front of the manual, if they can't fix it over the phone, there is a good warranty on it. At least for a little while. ;-)

I have an Ifit treadmill. I was changing speeds and it turned off and won't restart. It beeps when i turn it on but no lights on console.

Power issues with ProForm treadmills fit into two categories: the power does not turn on or the power shuts off when using the treadmill. If the power will not turn on, make sure that the treadmill is plugged into a working power outlet. In addition, you should use a single-outlet surge protector for the treadmill. Single-outlet surge protectors protect the machine from any voltage changes that may occur in your home.

If the machine is plugged into a working outlet, make sure the safety key is in the keyhole on the console. If the safety key is not plugged into the machine or if it is pulled out during operation, the treadmill will not operate.

Finally, make sure the circuit breaker located on the frame near the power cord is set to "Reset." The circuit breaker is set to "Reset" if the top of the button is pushed in. When the breaker is tripped, push it back to the "Reset" position and wait five minutes before powering on the treadmill.

If the ProForm treadmill shuts off during operation, check the power cord and circuit breaker as described above. You can also try removing and reinserting the safety key.

My proform treadmill stops when i reached around 30 to 40 minutes of exercise What's your problem?

Dear Sir:
I hope you are fine, and try it to help you.
The problem will be in electrical problem:
Disconect the power cord very important.
1) Check for continuity or short the power Cord with a DVOM( Digital Voltimeter) repair o replace
2) If the circuit breaker of the machine if tripped, Reset, 3) If the circuit breaker of the home or building are tripped, Reset.
4)Check the Voltage of the input of transformer, and secundary wind too. Smell if very hot or smoke? if this happen the transformer is faulty you must replace or rewind. But before you dismantling check the electronic component around, with DVOM, capacitor, resistor, diode, transistor is o.k or are faulty.
5)See if some wires is loosing tighted or solder it.
6) Finally the PCB will be faulty.Replace.
Thank you in advance, sincerely. Blessing.
If you need additional help, please reach me.

I have a Proform XT 90 treadmill that was recently purchased. After I brought it home, I plugged into my power strip and everything worked fine. Yesterday I plugged it in and nothing lights up on the...


A couple likely issues would be:
1. Is the starter key installed correctly?
2. Has the onboard circuit breaker tripped? The breaker reset is next to the on/off switch, which is on the lower front of the unit. Press the button once firmly. If this was the problem, the treadmill should work again immediately. If the onboard circuit breaker trips repeatedly, there may be a short circuit in the machine, in which case you may be at risk of shock if the unit is not repaired properly.
3. Has the circuit breaker or fuse for the particular outlet you are using tripped? Try plugging another electrical appliance into the outlet. Does it get power? If the circuit breaker or fuse has tripped, that particular circuit may be overloaded or faulty. Only an electrician could tell you for sure.

Please followup if you need further assistance.

Machine is plugged in but won't turn on. We haven't used it in about 6 months. Please advise as to what we can do. Other electrical appliances work using outlet that we have the treadmill plugged into.

Check the circuit breaker located beside the power cord. Be sure that it has not tripped. Snap it back into place if tripped.
Confirm that the on/off switch is switched on.
Insert the safety key in the slot on the front of the console. The console should light up.
If nothing lights up, I would suspect the power supply PCB, part #180635.

Treadmill causes electrical fuse to keep tripping and cutting off

Check to see if theres other loads on in that room(s). Usually if youre running something, and something else is turned on, the load can be more than the circuit breaker is able to carry. If possible, try using the treadmill in another area where there is little activity or not using so many things at the same time.
