My smeg A42 range has been tripping the house RCD recently when turning the main [fan] oven off.
Trial and error has led me to find that that if the fan motor is physically disconnected then the above fault does not happen. As soon as I reconnect it will trip again as soon as the oven is turned off. Someone has said that I must not disconnect the fan for long or the element will burn out.
Does anyone know a test I can do on the motor to prove that it is the motor causing this. I have a bog standard multimeter. (AC, and OHms).
Or can anyone think of another reason for this?
Thanks in advance
Stuart
