I purchased the Tresanti motorized sit/stand desk from Costco 4 months ago, and I think I found out why it was such a great deal compared to other desks.
This morning, it wouldn't move up from lowest position. It says "top" after about a half second movement, maybe 1/4". There is a new sound on the left side that sounds like a loose clunking. I would guess there is a mechanical sensor that is supposed to stop the desk at the top of movement, and perhaps that is loose and triggering too soon.
Anyway, that's just a guess, and I'll probably take it apart to try and fix. Since the desk is no longer in stock, Costco will take a return disassembled via UPS and assembled if I take it to the store. Other sit/stand desks are several hundred more than this, so trying to fix seems worthwhile.
Has anyone experienced this?

I was able to fix. One of those three appears to be a sensor that stops motor at top/bottom. It’s the ~1/8” jack looks like headphones. Unplug that one only, move desk up a bit, then plug back in.
FWIW Tresanti sent me a motor replacement before even talking to me about the issue, then I found out how to fix it while it was in the mail. Free extra parts?
My guess is the desk moved past the sensor and sensor is tripped while moving it back up.
This just fixed my desk 4yrs on still saving the day!
