Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
It is possible that you did not finish the calibration procedure properly, leaving the console stuck in a mode that is not the mode of normal operating or running of the machine.
Would you like to approach the problem with that in mind? if so, please Reply To Expert, and let me know, What procedure did you follow, doing the incline calibration?
OK, I see.
From what source did you obtain the instructions for that incline calibration procedure, if I may inquire?
This might be an important point. It may have left a step out, if it was a less-than-reliable source.
That (Proform.com site) page should be reliable as a source for instructions.
However, I need to ask one more question too: What was wrong with the treadmill originally, that caused you to try the calibration procedure on it?
This is by no means certain - it is a guess of sorts - but it may be that your incline calibration procedure was perfect, but the incline motor's controller board was going bad and after the incline, has now become completely defective. (This would only make sense if the 'path' through the circuitry by which calibration motions are ordered, were different from the path by which inline adjustments are ordered - since one works and the other does not.)
Given that this is a reasonable guess, I should ask, How old is the treadmill in question?
Then it is out of warranty for sure.
It is getting late here in the Eastern Time Zone and I have to quit for the night soon. But before I sign off, I should ask: Are you considering trying to fix the treadmill yourself, or hiring someone else or some service to do the repair work?
(I apologize for not responding sooner - I am in Eastern Time, and had to retire to sleep for a while.)
That is indeed the power board in question.
It has the main or primary transformer, and the two or three heat-sinked regulator components. It couldn't be anything but a power supply board.
But, I would advise you to get a 'motor controller board' instead. Indeed, taking apart the treadmill *first* (unless you have pets or small children about) is the best approach: you can locate the motor controller board and get the part # off of it, to be quite absolutely sure that you get the right component.
The motor controller board for the incline motor is most likely - though, not certain - to be the problem component. Not the power supply, which may be quite OK.
