Some may remember that I posted some time ago about my boat fridge and its failed CLD inverter which contained the controls for the fridge.
I have now fixed it. The solution was to buy two mains voltage contactors. One starts the compressor and the other the 12 volt pump. The contactor coils are wired in parallel and energised when the thermostat calls for cooling. The thermostat contacts, the on-off switch, and the over pressure switch are all wired in series and current flowing through them passes to the contactor coils. The fridge now works on shore power, or from the new Sterling Power inverter that I bought for the purpose.
