Yeah I guess heat-shrink would do the job most of the time. But for when you have connectors that are too big to fit the right heat-shrink over or want to splice more than 2 wires together and want a waterproof seal over them this could be useful.

Bad. I have a Raspberry Pi 4 hanging from a HDMI cable going up to a projector, then have a 2TB SSD hanging from the Raspberry Pi. I host Nextcloud and Transmission on my RPi. Use Kodi for viewing media through my projector.

Four loafs of bread later with no issues, opened it up and everything looks fine :)

The case is basically fully metal, just a bit of plastic inside for mounting the PCB to and a few other bits of plastic outside. Plus there is a temperature fuse in the case also.

From the resistor size (11.5 x 4.5mm) I think it would have been a 2W resistor when comparing to sizes on Digikey. I made a 500 Ohm 2W resistor from 8 1/4W 1K resistors then put a larger resistor in parallel to that to bring it down, measured it to 489 Ohms.

I’m going to run it a few times then open it up again to see if there is any new damage to the board before returning it.

Success!

Thanks! I’ll try replacing it with a 490 ohm resistor and see if it works again.

The element in the bread maker looks like it came loose a bit and made slight contact with the internal metal housing. I wonder if that caused the resistive element to sink more current than the PCB was designed for, burning out the resistor.
