oven fan not working and light perm on

Re: oven fan not working and light perm on

When you say the oven light, am assuming you mean the lamp that illuminates the oven cavity and not the neon indicator for the oven thermostat ?

Lots of assumptions here, cant really answer the question accurately without doing some electrical tests. This is not your typical fault/symptom so i think you have more than one fault that was initially caused by a short.

Circuit is normally made up of
Fan element (Most likely cause but leads to additional questions as to why the electrics haven’t tripped))
Stir fan (Possible)
Selector switch (Likely also faulty but not the cause)
Automatic Timer (If it has one)
Oven illumination lamp (its on so it works)
Thermostat (Normally cause food to burn or under cook so can rule this out)
Thermostat neon (Can cause odd issues )
Overheat thermal sensor switch (wont be this)

Most common part to fail would be the fan element, however in normal circumstances, this would have blown the fuse or tripped the RCD, you didn’t mention that it did. However if the appliance has a faulty earth, then it is possible for the element to have blown some of the contacts on the selector switch and welded the Oven lamp contacts together, hence lamp on, oven and fan not working.
Stir fans don’t normally fail electrically, they either just stop turning or get noisy, so the fan is an unlikely culprit but a remote possibility

Selector switches if they go faulty through their own doing simply stop turning something on, they don’t normally force a circuit to be permanently on. Sounds very much like the contacts that turn the lamp on are welded together this would be caused by a surge typically caused when a fan element blows with poor earthing.

Hope that helps

Good luck, please post back, I would be interested to know if i got it right 🙂
