Hi there,
I am looking for some assistance troubleshooting this board (or at least determining if it's out of my league :>). I have found a number of similar motor control board issues on here, but nothing specific to this particular one. Other possible relevant info from the board: 2.25-2.5 JC07-001 SJED08089IF Ver H109S106
Description of the issue: The treadmill had stopped and requested a belt lube (we have done this before, but it has never actually come up with the maintenance message). Lubricated the belt & did a thorough cleaning, reset the maintenance message, put it all back together & worked OK. I had started using it again, and noticed that the belt was slipping when I got it slowed down to a walk speed (wasn't happening (at least noticeably) at higher speeds). I was going to finish my workout and try adjusting the belt tension, when it made a popping noise (combined with a glitch on the TV), the belt motor stopped, and I could smell the magic smoke :>)
Troubleshooting done so far: I used some of the very helpful information on the Treadmill Doctor site to narrow down the issue. I tested the motor with a battery - still works. The control panel, elevation motor, etc. still work, and Treadmill Doctor indicates the issue is the motor control board. The red LED on the board does not light when everything is connected. I have removed the board from the aluminum mounting plate / heatsink, did a visual and "sniff test", but I don't see anything blatantly obvious (burned components, bubbled caps, etc.). I did a bit of poking around and *may* have found one bad diode, but apparently had a brain fart and forgot to document it...
My skill set: I have decent soldering skills & tools, and basic electrical / electronic knowledge. Although I did electronics as a hobby when I was younger, and went to school for electronics, that was in the 80's, and my jobs have been in IT. I could do some basic component testing / replacement with some help / direction. I would just replace the board, except for the cost (I was recently laid off, and am trying to conserve funds), and the concern that a replacement board may wind up in smoke as well, particularly if I am still having issues with the belt. The treadmill is a few years old, and I am not sure if the board is worth the cost to replace for the value of a used treadmill.
So whatever guidance anyone can supply would be greatly appreciated. Concern with repair is the amount of time and effort involved to make sure I get everything if there are multiple components damaged, with getting components, and with sinking a bunch of time and money into a project that is over my head, or possibly not fixable (at least by me :>).
I don't take offense easily, so please feel free to be candid with comments (but hopefully avoiding outright insulting :>). This looks like a great community with some very helpful members - thanks in advance, even if just for the information I have already found on here. I have added a couple of photos as per what I have seen in the other threads.
Thanks!
