unless a mouse chewed it it aint the wires
For the curious.
I am looking to identify the hot lead to the defrost heater. Whole fridge is acting badly. Broken ducts between the two sides, etc.
So in my cleverness I plan to have a separate module to power the defrost and automate that when the fridge is at the cold end of its cycle to once a day defrost. I have a method to my madness.
