Thanks for working on the weekend.

Your Welcome Dave, Caught me just as I was heading out.

Ok the problem here is going to be a separate one to the original problem, in this case the defrost system has failed.

Remove the panel on the inside of the refrigerator, behind the panel you will see the evaporator, looped below the evaporator you will see the defrost heater, Clipped to the top you will see the bi metal thermostat. With the frost still on the evaporator test the heater with a ohm meter, if it reads open it will need to be replaced. If the heater reads good then the bi metal clipped to the top of the evaporator is bad and will need to be replaced, Before you replace the faulty part make sure you melt the frost with a hair dryer.
