Hi, welcome to Just Answer. My name is XXXXX XXXXX I look forward to helping you! I am unable to locate the exact schematic, but this model does not appear too complex. Basically there are tow circuits, the compressor through the thermostat and the light through the door switch. What exactly are you having trouble with?
I have just shifted house. On starting the fridge I put a thermometer in the fridge compartment and the temp got down to -8 with the t/stat at its warmest setting and the compressor never stopped. Next I got a new t/stat from Stokes, a Danfoss 25t65 unit, same as the original. The new unit, with the dial in the warmest position, also never stopped the compressor, I stopped it at -2. It looks as if the t/stat is being bypassed somewhere, hence I'm looking for a circuit before doing it the hard way with a meter and stripping the wiring.
No, the thermostat has no off position . I switch it off at the power point. I cannot use the fridge as it is.
Yes. I stated that in a previous email.
I haven't got that far yet.
Sure. A circuit would have been nice.........
I remembered Ranco had a number of replacement thermostats under the Varifix brand and there was a diagram that told me I had swapped one of the three white wires and bypassed the switch to make it run full time. One white wire is the active for the compressor and the other two are for the drain heater.
Next I put a logger in the fridge and let it run for 13 hours. Average temperature 3.2C. In that time it cycled 20 times.
As I stated in the beginning, I was looking for a circuit and had wasted hours looking for one both under Kelvinator and Danfoss, but forgot about Ranco.
