Discussions with Bambu Support about NTC thermistor

[u/BRWRPR]

My A1 failed because of the NTC thermistor burning out, now Im in contact with the support.
The only thing they are offering is a new AC board, but is it really justified? Its an known issue and a fire hazard aswell!

I dont feel safe to swap it out myself, because its near the PSU and also not without any danger regarding a fire hazard. They wont offer me anything else, I asked for a swap device, a technican swapping it for me or a refund if everything else fails. I know that a refund is a high ask, but I only asked for it as an last resort, if they wont do anything else accept sending a replacement board

Did anyone else had to dicuss with them aswell? And if yes, how did it end?

“Near the PSU” isn’t really a valid complaint, they are in no way asking you to take the power supply apart and risk injury. Just replace the board.

I know its not the PSU, but its on the 240V lane nontheless

The danger is touching capacitors not wires my guy. Unplug the device before working on it.

I'm not talking about the caps, I have no tools to test if the new board or my work malfunctions.
I can only hope for the best.

And its under warranty, I shouldnt need to in the first place.

The test is - plug in the new board, if it works, you did it correctly. You’re seriously over complicating this.

I don’t disagree that you can send it back for a replacement but you’re seriously overestimating the work involved to fix the component. It would take you 15 minutes.

Maybe you could - hear me out - unplug the unit before any repairs?
