The evaporator is not defrosting, so the freezer compartment will not get down to temperature.
I would like to test the heater for continuity and test the thermofuse. If the thermofuse had 2 wires then it would be obvious how to test it for continuity but it has four wires? Does anyone know what these four wires are? (grey, red, Black, blue.)
Also, does anyone know where the clock is that controls the defrost circuit?
Thank you in advance
