What started out with a bent retaining clip on the left nozzle and a support ticket has now turned into a dead right heater. I wonder if I can unscrew the heater from my replacement left nozzle heater that comes tmrw and screw it on the right? not the entire heater block but just the heater and nozzle clip? The left and right nozzle heater and retention look identical from the front.
Anyone else have a heater die on them already?
I would make sure that your nozzle is inserted correctly and that it is tight up against the little rectangle sensor behind it. I would make sure that the clasp is correct and the nozzle doesn’t wiggle. Other than that I’m not sure
Can you show us a pic of the back side of the nozzle? Im wondering if you have a sensor imprint
“Temp malfunction” is usually thermistor, heater or TH board. Fingers crossed its not the latter, would be a pain in the rear to replace on the H2D. I had to swap one on X1, that tool head is much simpler but was still a long process.
I did take the right side heater and plug it into the TH boards left nozzle header and it errored out on that side as well. So I am assuming my board is safe since the nozzle doesn’t work on either side but the left nozzle does. I’m not sure what a sensor imprint is tho. Could you explain in detail so I know what to look for?
Ive just noticed some printers have the nozzle riding on the temp senoser, and some dont. Some have an air gap around the sensor. My guess is that the heater on those are overworking because the nozzle doesnt have good pressure against the actual heater. If you look at the back side of your nozzle, youll either see an imprint or not. If you post a pic, ill tell you.
It also seems to be the right nozzle
The brass or copper whichever it is, its making contact with the nozzle only at the bottom. for the most part it is not touching the nozzle. 95% of it makes no contact. You can right click the image and open it in a new tab for full resolution.
Nice. No sensor print. Thanks for posting. I hope everything works out for you.
Edit, sorry, I misread what you posted. And I looked closer at the sensor. Definitely looks like it only touching on the very bottom, like you said
Is the whole thing “golden” colored? Or just a camera thing? If it is golden, looks like it got super hot. Maybe the machine caught a thermal runaway.
You can try putting a very very thin layer of grease on the heater (or the back of the nozzle, but not both). Install the nozzle, and then take it right back off and you will see where it touches. Remove it again and clean it up before you use anything. But this should help show you and Bambu the contact area.
EDIT: Are those screws on the back side that hold the heater in place? If so are they snug/tight?
yea, everything’s tight. I got a new left heater in today and I plugged it into the right sides port on the TH board and everything shows up fine with no errors. So I guess that heater just died. I have no idea how fast support can get me a new part so I ordered one myself yesterday. still looking like a week away tho. This is going to cost me a few hundred in down time and I had to cancel some customers orders.
@max225719 Would you do us all a favor and let us know how your replacement works out after you’ve installed it and had a chance to use it a bit? This topic has some overlap with observations on a different thread regarding the same part:

Will do, Looks like most peoples thermal sensor protrudes a bit while mine wasn’t really making contact.
I could see this damaging the heater or sensor if you get thermal run-away due to this contact issue.
Well I just heard back from support. They are sending a replacement part. At this point tho I feel like a "hey sorry about that heres a roll of filament. We know we sent a dud, our bad) or heck a filament swatch for my collection is in order. Instead its just another week of a $3k paper weight rofl
For those of us trying to follow the evolution of this thread, exactly which part is Bambu sending you?
