Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
That problem *might* perhaps be a cheap-enough fix requiring some labor, a few tools and some time.
Sometimes when a belt over-speeds briefly and then stops, the problem is that it has not sensed the speed at which the belt is moving, and has shut down for safety reasons.
And sometimes the lack of sensing the speed, is because the speed sensor, a small component that is mounted near a rotating part of the treadmill's interior parts, which rotates when the belt is moving, has slipped out of alignment a little and is no longer 'reading' the rotating element.
Would you be interested in opening up the treadmill by taking off its cover pieces, and locating the speed sensor, then testing it (possibly with a meter, possibly just by watching an LED light on one of the circuit boards) and readjusting it as necessary?
This might not turn out to actually be the problem, but it is a first thing to try in this case.
The first step is, unplug the treadmill.
The second step is, locate the fasteners - probably screws - that hold the cover pieces on.
(You may have to turn the treadmill on its side, gently enough, to locate and remove the cover pieces.)
Then you remove those screws, and the cover pieces should come off easily enough. It's the base of the treadmill, where the belt is mounted and revolves, that you need to get at, not the top near the control console, in case it needs be said.
OK. Which cover are you trying to remove?
Is the machine on its side?
That sounds right! what you want to remove is the Motor Cover (part # ***** in this diagram):
It is indeed held on by three screws, with 'tinnerman clips'. Did the screws come all the way out?
There may be other parts, such as the side pieces on the sides of the treadmill walking area, that are keeping it from coming off. Does that look like the way it is?
(In that diagram, part # ***** a little coil to the left, is the speed sensor ('RPM sensor') that we're looking for.)
They probably slip off by pushing 'downward' so the clip slides off the edge of the cover piece.
With a small screwdriver, for instance, perhaps.
Try removing the side pieces first, to left and right of the belt.
See this diagram for help:
I suggest you put the treadmill on its side, and take off the bottom front cover - part # ***** at lower right in this diagram:
which is attached with six (6) screws, part # *****
(Put on the side piece that will be on the under-side, before turning it on its side, though. That might be best, anyway.)
Did the bottom front cover come off at least? part # ***** in the diagram.
Can you give me a picture of where the cover is binding, sticking, or just not coming loose? and post it to your reply?
You may need a longer screwdriver. Have you made sure you are using the right, straight-blade vs. cross-blade/Phillips screwdriver ?
Could you post that photo of 'tread mess' in JPEG format rather than DOCX, please? I have a system where JPEGs are much easier to view than DOCXs, though I can manage it with some labor.
Thanks! OK, I see that I was wrong. There are two fasteners there. That can't be reached from outside.
I honestly don't have more advice to give on this. Disassembly is usually fairly easy - just unfasten everything, and take off the outer covers. So, if you would prefer to wait for another Expert's advice on this problem, let me know, and I will Opt Out, opening the case to others.
I have Opted Out. The case is that of disassembly of a treadmill, to determine, and remedy if possible, the cause of an overspeed-and-shutdown of the running belt.
As for a refund: I cannot do anything about that except to refer you to Customer Support at JustAnswer.com... you can contact them through
Thank you for working with me on this matter, and I hope that some of my advice may still prove useful to you. Also, though Opted Out, I can still respond to any further postings to this case, should there be need.
