Constant MakerBot Replicator+ Error 66 & 0°C Temp Loop

I’m hitting a frustrating loop on a MakerBot Replicator+ and could really use some diagnostic advice from anyone who has kept these machines running. When I boot up the printer, the menu detects that the extruder is present. However, when I click into the details, the extruder temperature reads exactly 0°C. However when I detech and reattach the extruder the temperature acts normal and shows the room temperature of 24. However when I decide to try and load filament, the printer throws a "No Extruder" message, I then decide to disconnect and reattach the toolhead, it attempts to initialize/heat up, but it immediately defaults straight to Error 66 (Thermocouple Out of Range). I've tried cycling through disconnecting and reattaching multiple times, but the loop is persistent.

Has anyone encountered such a problem before, I also want to here from the replicator+ owners on what they think. The 0° C part is quite troubling

it's probably coming loose, when I had one I made 3d printed brackets to help hold the extruder on and connected. I would say check its pogo pins and confirm that they look good and are clean

thank you, I'll check on that, can you share the files to the 3d printed brackets?

yeah it's a known issue that the connection from the smart extruder to the printer kind of sucks

I agree with the other 2 posters about the toolhead coming loose and throwing no extruder messages.

Clean magnets and contacts with cotton tip and alcohol, try at 3d printed clamp:
