SMEG cooker oven cuts out

Can you explain in more detail? Is it tripping electrics?

if it cuts out and comes back on later could be a cooling fan problem

The problem has been ongoing for a month & we cannot use the oven. We removed all the elements & checked the resistance & they were fine. We also checked the resistance of the oven thermostat & that was also fine. We then ordered a new tangential cooling fan as well as a cooling fan thermostat & replaced that. Unfortunately it’s still not working. The moment the oven reaches about 140/150 degrees, it shuts down completely. Even the clock goes dead. After about 15 minutes, we can switch it back on again. Although we’ve replaced the cooling fan, the cooling fan doesn’t actually switch on. The oven doesn’t trip anything, it simply switches itself off. We replaced the cooling fan because after doing lots of googling it seemed like the most plausible problem. We had hoped that the fan’s motor had packed up & that by replacing it, the problem would be resolved. Does the fan maybe have a controller that could be broken? Thank you for the feedback.

Hi,

I mean if the cooling fan doesn’t come on then it will shut down to stop overheating. Is there voltage 240v going to the cooling fan?

It sounds like one of the tocs on the back of oven you normally see a burn Mark on the connection or the toc itself

Thank you for the replies. What is a toc?

There is little to no resistance across main thermal cutout thermostat. Not sure if 240V is going into cooling fan. We shall have to pull it apart again to check.
