They haven’t got a thermostat, just a probe sensor. The customer says the temperature is never correct. Is it quite common for the probe sensor to go haywire or is it more a circuit board fault? Many thanks June 16, 2014 at 6:28 pm #415324 MartinParticipant Re: Hotpoint DE89X/1 main oven thermostat Sensor more vulnerable to failing.
