Dear Sir:
Please RUN THE software calibration for easy diagnose and troubleshooting, and adjust the speed sensor see the diagram attached.
And you will see the problem with the motor, possible lack of LUBE, and maintenance.Now you test the motor for lubrication and maintenance too.

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.

SOURCE: My Proform XP Trainer 580 started to speed up

Dear Sir:

Thank you by your request, I hope everything is fine.

I will try to help you inmediately.

Connectthe test leads to the volt-ohmmeter. Plug the black test leads into the blackjack marked "Com" or "Common" on the front of the meter. Plugthe red test lead into the red jack marked "Volts/Ohms" on the frontof the meter.

    • 2
Setthe meter's function switch to "Ohms" and the range switch to the"R x 1" scale. If your digital multimeter is an auto ranging meter,you will not have a range switch. Instead, you'll have just a function switchbecause the meter will automatically select the right range for the quantitythat you are measuring.

Turnoff the power and remove the fuse to be tested from the circuit. Never test afuse for continuity while it is still connected to the circuit that it is usedto protect. If the circuit still has voltage, the meter will be irreparablydamaged. If the fuse is still in the circuit when tested it is possible to geta false indication that the fuse is good if the meter gets a completed circuitthrough other circuit components. To be safe, always remove the fuse from thecircuit before testing it.
    • 4
Touchthe black test probe to one end of the fuse and the red test probe to the otherend of the fuse. It does not matter which probe you touch to which end becausefuses are not polarized. You are checking to see if there is continuity throughthe fuse element. A reading of approximately 0.5 on a digital meter's LCDindicates a good fuse. Most digital meters read their own internal fusesresistance, hence 0.5 Ohms and not 0.00 Ohms. LCD readout of "O.L."indicates no continuity through the fuse. The fuse is bad and needs to bereplaced.
I hope that you can Handle the DVOM(Digital Voltimeter)
Thank you in advance, sincerely. Blessing.

SOURCE: I have a proform xp

If you can walk on your treadmill but you get a burning smell from it, you have a bad problem and discontinue use immediately and unplug the treadmill.

Burning smells are most commonly associated with the following problems:

1) Very high belt/deck friction.

2) Short in the motor.

3) Short in the wiring or electronics.

4) Literally cooking the lacquer or cardboard core (on cheap machines) in the motor from belt friction or a drive system

obstruction.

Friction is the #1 cause of this problem. Many cheaper treadmills have a motor with a cardboard core (people wonder why we are so

down on cheap treadmills) and if the voltage and amperage through the motor heats it up sufficiently, it begins to smolder. If this is the

case, you normally have to replace the belt and the motor and inspect the deck. If the armature has cooked enough in the motor, you

also have to replace the motor.

If the belt and deck check out OK, check for a short in the motor. You can run the motor with an independent power source like a fullycharged

cordless drill battery to see if the symptoms are the same. Click on the following link for our motor test.

If the belt and deck check out and the motor is OK, then check your wiring and electronics for signs of scorching and replace the

appropriate part(s).

I have a Proform xp 615 that will work fine for about a minute and belt will stop. As soon as I step off of the belt it will run back up to speed, but will not have any power/ torque.

Hi There, This could be caused by a few things....
First, is the belt/deck lubricated and slide easily with the foot when the treadmill is off? Next, , have you noticed any odd smell like burning "something", if so, this would lead to a motor issue, which can be checked with the tread UNPLUGGED from the wall, look inside the motor brush covers, one on each side, to check the copper colored commutator for dark burned area's, and lastly, motor control boards die over time due to the work on the capacitors when the treads are in use. Unfortunately, manufacturer's decide to cut costs on capacity for overall performance which leads to issues, and you can always email gregATbuyfitnessrepairpartsDOTcom for additional help, as nobody likes a dead-tread ;o)

Fluctuating speed

With the motor being new and the "hot electrical" smell, I would say the motor control board, which sends the speed command to the motor, would most likely be your issue.

I have a proform xp 550e trademill and i changed the motor control board because the motor start running and inmediadlly stops. after i installed the board the motor start running and stop some time after...

To calibrate the speed follow these steps.
Press stop and speed up and place the safety key in its spot.
release the stop and speed up.
Press stop again. The windows on the console (speed & time) will be all zeros.
Press speed up, the time window will increase. The belt should start to move. Increase this number to 85. This is maximum speed. Adjust the potentiometer to the correct maximum speed. The console will beep until the correct speed is adjusted (+ or - .2mph).
If the machine suddenly goes dead when in use, you may have a static electricity problem.
Check that the ground pin is present on the plug and check your outlet for a proper ground connection.

How To Lubricate Treadmill
10helpful
1answer

My Proform XP 650e Treadmill starts and suddenly stops. The belt turns real fast then it suddenly shuts down like the power was turned off.

This condition is when the treadmill goes to full speed as soon as you power up the treadmill. Typically when this occurs, it is an indication of a short circuit in the motor controller.
