Okay, so I found this site while searching endlessly on Google for help on repairing this damn thing! I actually graduated with a BS in Electronics Engineering but never used it and actually went into the computer field. Anyhow I got burned buying my treadmill off of CL after my handed down Precor (20+ years old... great product) finally gave out. So the couple that sold it to me "seemed" VERY friendly and like genuinely kind folks. Purchased it from there home and was told that the reason it wouldn't go full speed was because they didn't have the proper power. It was an older home and because I know that my Precor needed a 20Amp circuit and kept blowing the standard 15Amp outlets which are mostly in my home... it made sense to my stupid mind! I get social anxiety too... another story.
Anyway when I got it home, as is my nature, I completely broke the thing down for two reasons. #1, as I said it's in my nature... to completely clean stuff I buy from other people and I mean CLEAN. There seemed to be a mouse issue somewhere in the lifetime of the treadmill because I found a fair amount of droppings on the hidden parts of the treadmill (side walking deck support, circuit board, etc). So I disassembled it which was rather simple after all it is just a treadmill. Washed everything with pine sol, bleach, elbow grease... the thing is practically new now. Oh, and #2 because the damn thing was very heavy and it took two grown men to get it on the trailer, alas it was only me when I got home and needed to get it off the trailer AND up the stairs to it's final destination.
So after cleaning, transporting, and reassembly I fire the thing up and it throws an error code but it's just because the speed sensor needs adjusting, so I do that. Try again and the belt will not get up to top speed which is 12.4mph. The motor tops out at about 7.0 and whenever I step on the belt it bogs down terribly. Performance is frighteningly like that of when I walked on it at the couples home and was told the reason was due to the power outlet it was plugged into. Anyway, I've ruled out the motor as being faulty as I had a known working one to swap it out with and same symptoms. Further the brushes on the motor are fine, and the magnets also seem okay. Upper control boards are the cleanest thing on the treadmill and they seem fine. Connections to everything are good as well as the wiring. Considering the mouse fecal matter previously on the board and the suspect physical condition of the board amongst all that's already been explained... my guess is that I need a new DC control board. A quick search on Ebay, et al showed that I was going to be out another $250 for that part! Now a reminder... I went to school for this stuff so I do have the ability to big picture things. The big picture here is that a few components which might amount to a few bucks is/was going to cost me an additional $250 on top of what I already paid for the damn treadmill in dollars... not to mention time and effort. WTF?! Which brings me here. I'm hoping someone can shed some light on this damn circuit, what it does (it's really been that long), testing methods, suggestions, guesses. It's been 4 weeks (going on 5 now that my previous treadmill broke and my body is suffering greatly). I really NEED to get this thing working.
I've attached detailed photos of the DC control board. Let's get this started.
