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!
I need help troubleshooting my brand new tresanti desk I got from Costco (haven't even worked a day yet with it).
It appears that the measurement is off on the desk meaning when I press down it says "bot" but the desk is in a standing position (probably was 40ish inches when I put it in this place). My preferred sitting height is where it usually would bottom out, but now I can't get it to go down.
I've read the other troubleshooting posts and when I disconnect the headphone-like jack it disconnects the power to the controls so I can't move the desk. If I move the desk up as high as it will go it eventually sends an E2 error and never reached 'top."
Does anyone have experience with this issue? The desk is functioning fine (no unusual sounds, feels smooth), it just has the height counter wrong.
TLDR; my new desk says its at 'bot' when it really is a standing position and I need help resetting the height orientation. TIA
My Tresnati desk from Costco is not working and the customer support has been pretty terrible so far, they want to create a ticket with ALL my contact details just to help...it feels scammy. Does anyone have a fix for the "E3" error or the TOP error? My desk is currently stuck in standing position and I can't fix it.
So a few years ago, this desk was sold at Costco, and since then it seems several people have had issues with it.
In the first case, the circuit board falls out of sync with the stepper motor, which is easily solved by moving the desk all the way up with the 3.5mm jack disconnected.
However, in my case, the circuit board was stuck at "BOT", preventing the desk from going down and moving the desk up any significant amount resulted in a "E3" error code, indicating no signal from the motor.
CS will automatically assume that this means the motor is bad and will offer you a new motor under warranty. This will work if the motor connector is loose or the motor is stuck. However, in my case it was the desk-side connector that was loose, as evidenced by bending the connector with my hands fixing the issue.
Repairing this requires cutting off the rubber housing with a box cutter, removing the pins with one of these and then crimping on new Minifit Jr pins with a Molex crimper. I also recommend some heatshrink and Sugru to seal up your work. If you do custom cabling for desktop computers you should already have the necessary tools, otherwise you will most likely have to buy.
Hello - wondering if this subreddit might have any advice.. recently my standing desk keeps making beeping noise and locks/unlocks the controls for going up/down.
This is not the desk getting stuck at the bottom like most of the other posts about this desk - the desk still goes up and down. It just randomly makes beeping noises when no one is even near the desk.
Wondering if the power adapter could be failing or might it be something else? I've tried disconnecting/reconnecting all the cords.
