How is the tension set on the tread of the treadmill? The tread stretches a little with use and the rear tension adjusters will need to have tension adjusted for the "longer" belt to keep consistent tension on the tread beiing driven by the treadmill motor. The procedure is described in the Owner's manual.

Thank you for your question on the speed of the treadmill going up and down.

It sounds like a friction problem or the walking belt is too tight.

You can try the push test. Stand on the front end of the walking belt and firmly push off to see how far you will coast down the walking board. If you end up 3/4 of the way down the walking board then friction is not the problem.

If you only go a foot or so then you have either a worn belt or the walking board needs to be cleaned. Since you have already check for the belt being too tight and because of its age I would say that you may have to change out the walking belt to resolve this problem.

Please let me know how the test went and we can continue to troubleshoot with that information.

I will include the parts information for a new walking belt in the link below.

I have done a push test, with the incline at max, and push forcefully and end up at about 3/4 of the way down. I thought that the belt might need lubricated but in my manual it specifically says not to lubricate the walking belt. I do have the tension on the adjusting screws maxed out. However, the belt feels like it is adjusted properly. I have about 2.5" of lift on the center of the belt. Should I try to loosen the belt to see if it is actually to tight? I should add, the belt does not seem to be slipping at all. We have had that problem before and it was resolved by tightening the belt. The problem now is that the motor speed goes up and down and will not stay on the setting.

Thank you for the update on the treadmill motor speeding up and down. Have you check the circuit for where you have the treadmill plugged in to make sure that the treadmill is not sharing the line voltage with another appliance that is running at the time. It will need to be a full 115 to 120 volts at the outlet. Yes I would suggest trying to loosen the belt a little to see if that will help. With the tension screws maxed out it indicates that you belt has aged out and may need to be replaced. But it could also be the current limiter trying to compensate for a worn walking belt. If you feel comfortable with removing the hood and checking the setting on the current limiter speed pot on the control board you could try to turn it up just a little to see if it will help. Please unplug the treadmill to do this adjustment because if you do it live and you slip with the small adjustment screwdriver you might short out the motor control board. Technicians do the motor controller board adjustments with the unit running but they know how critical it is to make sure that they do not damage the board. Sam A.

I loosened the belt and that did not help. I have already done the calibration procedure where you run the treadmill at 10.0 and then adjust the speed pot to match. I did it with the treadmill running, carefully. That did not help either. This only happens at speeds above 5.0. You set your speed and begin running and then you can hear the motor slow down for a while, then it will speed up, and slow back down again.

Thank you for the update on the treadmill. I want to thank you for all your work on diagnosis of the treadmill. The only thing I can suggest is to replace either the motor or the motor controller. But it is not a sure thing unless you replace both. Due to the cost of these parts you may not want to replace both of these parts. The motor is about $292.00 and the motor controller is $135.00. I would go with the motor controller first if you decide to do the repair. Please let me know what you decide to do. Sam A.

Q:

Pro-Form XP 542 E TREADMILL

A:

I did a search using your model number and I located only one link that is on a unit shutting down. The link discusses a treadmill that shuts down while in use. The checks would be the same to determine the problem. Review this data while you wait for an expert response from our team. I hope this is helpful for you and enjoy your morning.

Thank you for your question.

I am sorry you are having a problem with treadmill. I will be happy to assist you. First, unplug the treadmill from the wall. Then remove the motor hood and check all the electrical connections. If they look ok, plug the unit back in and see if it lights up. If it does not light up you will need a voltmeter to determine the problem. If you have a meter and feel confident checking life voltage, follow the diagnostic chart in the image below. Just click on the image to enlarge it. Once you determine the fail you can order the parts from the following link. Craftsman tractor parts
I hope this is helpful. Please let me know if you need further assistance.

Q:

ProForm XP 542E belt problem

A:

I understand that your belt is not moving but everything is displaying properly. I have taken some time to research your question here on the Manage My Life website and I noticed that someone else had asked a similar question with a posted response from an expert. I attached the link below for you to view. I hope the link that I provided is helpful.

I have attached the calibration procedure. Run it through this procedure for the speed part and see if anything happens. It may just have had a glitch in the programming and needs to be reset. If that does nothing to change the situation the problem will like be the control board. Something to try that can indicate that is if you press the speed up button and then start to walk on the treadmill to see if it will catch up and start running. If it does, the controller board has failed.

Let me know what you find after doing these 2 things and we can proceed from there as needed.

Hi, Sorry for the long delay (meningitis emergency - everyone's fine). I followed the link that Alina posted - trying to push-start the belt didn't work. That's also the first part of what Wade posted. The 2nd part of Wade's post was trying the calibration routine. When I push and hold + and put the magnetic key on, the treadmill just powers on and thinks it is moving. Eventually it gets up to 10MPH and I am losing weight like crazy while the belt doesn't move :) I tried putting in the key and holding the Stop button and the screen said: 558 E 349 I think that has something to do with english/metric. I didn't bother changing that. The elevation works fine. Anything else to check? I did try leaving it unplugged (ended up being over a week) and that did not make a difference either. Is there a different calibration procedure for the XP 542E? Thanks! -Eric

A:

To enter the calibration procedure you have to hold down the speed + button while you put the key on. That didn't seem to work for you though. Just for the sake of trying, hold down stop and speed + while you put the key on and see if that changes anything. I think you may be getting into calibration and you don't realize it. One of the things it will display when you get into is the top speed, which is 10MPH. So it is very reasonable to think that you would see 10MPH in the speed window and the belt not be moving. Let's assume you do that and get to that spot again. Then press the stop button, count to 5 and press it again. This should put you in the level 3 of the calibration. If you press the speed + button at this point, the belt should begin to move. If it does not move we have a problem that it outside of anything calibration is going to resolve. If the belt does move, go ahead with the level 3 calibration procedure listed on the previously attached document.

Speed + and STOP worked. I went through the different outputs and the calibration procedure. The elevation calibrated, the speed did not move at all. Here's the different outputs from the different screens: 110 UEr time 19r0L time 100SPd 15 1n (or is that supposed to be an in?) 10 inc 10 c r FF cHS 1PLS 255c0d Pushed STOP button Did calibration routine. Elevation worked, speed did not. Pushed STOP button Control panel LCD cycled everything on and then everything off Pressed STOP button 558 E 349 Removed POWER key Any chance there's a wire not connected to the motor any more? Would the treadmill be able to recognize that? Thanks! Eric

The machine wouldn't recognize it to point out, no. Unplug the machine from the wall and then open up the motor hood. You will notice the drive motor sitting with a small belt (the drive belt) going to the roller. From that motor you will notice a black and a red wire. Follow those 2 wires back to the controller board to make sure they are connected. If they are then we know we're hooked up correctly and that should be no problem. If you have a volt meter we can check the motor to see if it is good or not. That will tell us a lot. You can let me know if you have a meter and we can run that test if you're okay with doing that sort of stuff. Please do make sure you unplug the machine before you open the motor hood, I would hate for you to get shocked.

Okay. To test the motor: Unplug the machine from the wall. Then unplug the motor leads (red and black) from the controller board. Connect your meter up to the motor leads and set meter to read DC volts. Then put the magnet key on the machine and start to walk. Do not press the speed keys or incline. Just start walking. When you reach 3MPH look at your meter readout and it should be no less than 28VDC. The motor is DC so it will act as a generator when you manually walk on it. If the reading at 3MPH is less than 28VDC, the motor is bad and will need to be replaced. If it checks out at 28VDC or higher at 3MPH the motor is fine and we are very likely looking at a problem with the controller board.

Hi Wade- I cracked the motor housing and tested the motor. I was able to generate >28V when pushing the belt with my feet. I tested the connectors on the board - that always showed 0.0V regardless of the speed setting. While looking at the diagnostic paper that is inside the motor housing, I saw a bit of information which said there should be an LED that lights up on the motor controller depending on things like getting power, how much is being delivered, etc. That LED never lit up. The final thing I noticed when going through the calibration routine is that the Checksum entry said FF which means Flash Failed according to what I've seen. My guess is bad controller board. What do you think? Thanks for all your help! -Eric

Correct. If you got the FF and the LED is not lit, the controller has failed. At least we know the motor is good though, so at least we do have something positive in all this.
