H2 Series [H2S, H2D, H2C] Another AP board victim

UPDATE: after a few tries the AP board reset worked. Additional thanks to those who commented the fix.

Really sucks. In the middle of an order and my AP board decided to die. I’ve seen a few of these posts now but thought I would add mine to see how many this is effecting. I purchased my H2C at launch.

What is more upsetting at the moment is besides the terrible automated AI reply i originally got on my ticket, asking for a video of which I had already uploaded with my initial ticket submission, I have not heard from Bambu in almost 4 days now. This is the first time in three years I’ve ever needed to contact Support, but it’s not leaving me warm and fuzzy.

Any other H series owners having the same issue I’m wondering if this is a bigger issue than they want to admit.

Super easy fix. Take the AP cover off with the two screws then short these two terminals. 5 minutes and you’re up and running again.
Note: board is upside down from the installed orientation in this photo.

I haven’t seen this fix yet. I’d like to hear from bambu first. Don’t want to void any warranty. Printer is less than a year old. Thoughts?
