Any treadmill gurus out there?

They thought they could repair it for less than $180. Received a message that it was not repairable. Did not say what the issue was. I had the option of letting them recycle or send it back to me. I opted to have it sent back. Return shipping was $46, which seems a bit high. But, to be fair, they may have charged some bench time for the attempt.
Found a used on on Ebay. Same model number. Looks much cleaner than the one I took out. I believe my treadmill sat in a garage for quite a while before I purchased it used. Showing some light surface corrosion. Seller has agreed to take it back if it does not work.

I suspect these control boards have a common part that is the weak link, and if that particular part fails, they can fix it. Otherwise, they just don't look. Back when we had an in ground pool, there was a large control panel that cost about $1,000 to purchase. Turned out there was one part that routinely failed. I bought a box of 5 for less than $10. Replaced it twice and it worked each time. When we sold the house, I showed the new owner where that board was and showed him the little baggie taped inside with three extra parts. Don't even remember what it was called. Just two connectors that had to be de soldered and then soldered back in.
