Electric cooker oven hob repair , testing and replacing thermal cut out overload over limit thermostats

Very easy job to both replace and test these just a screwdriver to undo the back panel to gain access to the terminations and a basic multimeter. You should get very low ohms reading as it is just a thermostatically controlled switch basically and should be on all the time it will only open the circuit if the temperature goes about a set perimeter which is usually stamped on the device itself.


Symptoms would be no power to oven at all or just will not get hot , but test first and test elements as well to ensure you replace correct part.

Pull of both cables and you can test it for continuity 
it should be very low ohms resistance reading as this is 
just a safety switch and should be on at all times.
