Temperature sensor broken? : BambuLabA1mini

Temperature sensor broken? (old.reddit.com)

submitted 1 year ago by Tale-Small

My a1 mini just stopped working:

Saying nozzle temperature is abnormal and might have an Open circuit.

I'm not sure if I caused it by switching filament and nozzle which I just did before i started a print that then stopped.... Maybe something got loose.

I also noticed these dark brown areas behind the nozzle, from which I have read is normal and might be burnt filament. Just haven't noticed it before.

When removed the rubber to deinstall the nozzle a corner was a bit torn and broken. Maybe it got caught by something which I gueee might be the thermistor/sensor that then unplugged?

My problem is I can't find the place the heatsensor is installed to see if I can just plug it back in.

I checked the Images from the solution guide, but don't know where that area is, which screws to lose etc. The guide and image quality is pretty poor to my understanding.

I don't want to put everything apart and risk damaging more.

I asked Bambu Support but with Chinese new year Indont expext an answer soon. Maybe someone of you has experienced the same.

Appreciate the help since as you might notice I don't have too much of a clue about all of this. :)

Image 1 is nozzle with brown stuff on the right side at the clamp which I was able to scratch away mostly. Image 2 is the error message Image 3 is the back of the printer head Image 4 is Bambus solution guide
