Thanks, ***** ***** your reply
its in a holiday home, the original one some one has turned the dial too far and snapped off the knob, I have temp fixed by taking to pieces, setting the temp then re fitting. so original still in appliance.
sorry for the delay been away from office, I could just replace the knob but I have tried to get the one out of the new pcb but it doesn't seem t want to come out, afraid of breaking it and costing another £80.
Any suggestions welcome. will not have access to fridge now till next week so no rush
