[/quote] Did you remember to plug it back in and switch it on?
How were you removing the inch of ice? Could you have damaged the cooling pipes?
Usually if it is freezing up and too cold it is the thermostat at fault and not opening. Not freezing now could also indicate the thermostat is now not closing.[/quote]
Yes definitely put the plug back in the socket, switched on at the socket. Also put it on "boost" or fast freeze. My Mother turned off the boost about 24 hours later.
I put small quantities of very hot, but not boling water in mugs, baking trays etc. and let the steam do most of the work. I was very careful not to bash, chip away at, or otherwise make contact with the cooling pipes. I am not intending to make an 80 mile round trip to sort this out. Her excellent Handy man will be there on Tuesday, so I will ring him on Monday night to explain the situation, and ask him to have a look for anything obvious.
