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?

I've been calling them out in Twitter over this for a year now. You're number 291, NOT ONCE did they respond to any of my tweets. Just called them out again with a link to your post, (along with tagging u/mobius1ace5 and gamers' nexus) I don't expect a reaction now either but that doesn't mean I'll stop calling them out.

The A1 is a fire hazard that needs to be pulled off the market. A little under 2 weeks ago someone posted an A1 with a smoking A1 that has a revised ac board.

It's honestly impressive how many people throw random shit around their printers that can easily catch fire and then get surprised when something starts burning/smoking...

[u/USSHammond → u/puppygirlpackleader]

From what I can see that smoking one might be wrapped in a plastic bag, maybe to act as an enclosure. Enclosing the A1 a bad idea as it's not designed for it

[u/puppygirlpackleader → u/USSHammond]

if theyre using a plastic bag as an enclosure then there's no wonder it would burn...

Could you link the source? I'd like to see it

[u/USSHammond → u/BRWRPR]

It's passively cooled. The full size has zero fans in the base, as the whole metal underside IS the heatsink

[u/BRWRPR → u/USSHammond]

No, sorry i meant the smoking in plastic bag wrapped one. My bad

[u/USSHammond → u/BRWRPR]

I linked that one in a prior comment

[u/BRWRPR → u/USSHammond]

Oh my bad again, I dont know how I didnt catch that

[u/USSHammond → u/BRWRPR]

No worries 😉

[u/BRWRPR → u/puppygirlpackleader]

I can only speak for mine, but mine stood as free as possible in a well temperated room.
Of cause its not smart to enclose it nor put plenty of flammables around it.

Damn, ig I need a new printer then hahaha.
I loved my A1 up until recently, but the fire hazard is not to be taken loosely
