the engineer hit the side of the freezer with his hand and said he thought it was a problem with the circuit board behind the front panel as the lights were still flashing. The engineer took details of the model, photographed it and went away. I got a call next day to say the part was obsolete so they could not get it and have you a card we can take payment on for the engineer's visit. On looking on the internet this part is not available and has not been available for a while, I thought the engineer should have an idea of this and said something when he called.
