Question

My dometic 4230 fridge. works on gas and 12v but not 240. Green light is lit. Thermostat? Is it easy to change? Thank you.

Answer

The most likely fault with your fridge is that the 240 volt heater has failed. General instructions on replacing the heater are covered in my answer posted on 13th February 2012. Heater ref 139569 will be required.
