One last attempt. Still haven’t resolved the problem. Could it possibly be the fan? Some electrical issue causing it to cut out???

[Boris45]

So is it worth replacing the thermal cut out switch?

[Boris45]

Ran the oven with the backplate off. Ran perfectly for 27 minutes, no cut out. Could it be a ventilation problem? Where do ovens draw air from? If I locate it and clean or vacuum, might be worth a try. All seems to work fine.

I’ll try to look at the element and fan as the oven runs later. Would the thermal cut out then stop the fan and the element? Could then be it!

[Boris45]

Strange then that the fan in the main oven switches itself off. I wonder why??

[Boris45]

You have me very interested now. What switches the main oven fan off? Should it not remain on during cooking? And should the element glow red during cooking?

[Boris45]

I’ll have to take the back plate off again, let it run and look more carefully at the element. From last time I remember the element did heat up and glow orange but didn’t stay like this for very long. I suspect once the oven reaches temperature the element switches off? The model number is DC740SS/3. I just don’t remember the main fan ever switching off before during cooking.

[Boris45]

Yes it has a cooling fan. It does run when needed. However, I’m referring to the fan in the main oven, located behind the back panel. An engineer will diagnose the problem for 40 pounds, then return with a parts and charge labour thereafter. Pricey.
