Reddit reviews Thermal Fuse Thermal Cutoff Limiter 128c Degrees Celsius

You'll be looking for something like this near the heating coil, I presume. It could be elsewhere also but once located, see if the temp & amp ratings are legible and order exact or something close.

Edit- A continuity test across the ends will let you know if the fuse is the culprit...infinity=blown.

Yep I've said the same thing in the subreddit. Always buy a thermal fuse that permanently blows. The one from the BOM will reset itself IIRC. I believe this is one of the ones I've used in the past printer bed only needs to go to ~110 for ABS, that gives you a little leeway over. I use rescue tape to secure them to the heating pad to make sure they will blow if the need ever arises.
