The oven completely looses power and switches off, it doesn't blow the fuse or breaker, it is like an internal fuse/breaker.

From searching online, the symptoms point to the thermostat. The oven gets to a certain temperature and the thermostat cuts power completely to the oven.

This isn't how the thermostat should work, when it gets to temperature and then stops the heating element with all other power still working, it completely looses all power to the oven. It has to cool for a few minutes, then totally reset, including the digital clock.

I am pretty sure it is the cooker thermostat that is faulty, this weekend I am going to try and take the cooker out myself and see what the part is and how much it is.

I think you're right that cutting power to the entire oven isn't something a thermostat (faulty or not) should be able to do. It may however be that the thermostat isn't turning off the element, so the oven overheats and trips a separate safety device that protects it. If it's a thermal cut out, your oven should not be able to be revived instantly after it stops as it would need to cool down a while? It should also, if it can be restarted while already warm happen again much sooner? If you can turn it back on instantly and it takes another 20 minutes again however, I strongly doubt it's a safety cut out based on temperature, which would lead me to suspect it's not a faulty thermostat allowing it to overheat.

Anyway, the thermostat as the cause is very plausible, but I would also check out other possibilities, including the fan has stopped spinning, as this would also cause overheating, and an accidentally set timer. They too are very plausible causes.

Do you have a portable oven thermometer ? If so you could test the oven by putting it inside at the top and seeing what it reads when the lecky trips . If it is above 240 C it's the oven stat faulty.


Personally I would be getting it professionally serviced.

This is very plausible I think. If you have not got something to measure the temperature with does the oven not have a light that goes out when it reaches temperature? set the oven to 180 and wait see if it ever reaches temperature and goes out or just keeps going until it trip the other overheat sensor.

If there is no indicator to tell when its still heating or reached temperature do you have one of those electricity consumption monitors (not the plug in ones, I mean the sort that has a sensor connected in the fuse cupboard) as long as you were not switching other big loads on/off at the time this would show by the high consumption if the oven element was on all the time instead of cycling on/off to keep temperature.

Have you used many aggressive oven cleaners or had it done by a cleaning service? often up near the top of the oven is a metal tube that is the thermostat sensor, I have seen these rotted through by caustic cleaners.

Parts shouldn't be a problem to get, most brands share common parts across a range.
