Oven control panel heats up

tyllwyd

We've got an AEG fan oven, and while it is turned on there is a cooling fan above the oven which keeps the temperature down in the space between the oven and the cabinets. The air generated comes out through a slot running between the panel with the oven controls and the oven door.


After the oven is turned off, the fan runs for a bit longer, then there is a thermostat which turns it off when a suitable temperature has been reached.


The problem is that the oven is still pretty hot at that point, so hot air starts escaping through the slot and the panel with oven controls heats up to the point that half an hour after cooking it is uncomfortably hot to touch.


That seems wrong to me, but the oven has been checked and OK'd by service engineers, so I am doubting myself. Can anyone tell me, is it normal for oven controls to heat up significantly after you have stopped cooking?

The control knobs remain cool on ours, but the panel itself gets very hot in operation and remains so for some time. It seems very wrong to me too, but it is a cheapo oven that came with the house so I don't complain.

I would expect better from AEG though.

I have a different brand with the same feature, everything stays nice and cool.

Sounds like a design fault to me, you shouldn't get hot air escaping through that slot.

Thank you! I can't believe it is right, why have a feature which keeps everything cool when cooking then allows it to heat up to a significant degree afterwards. The engineers have replaced the fan (twice), thermostat (twice) and another component as well, but it is still happening. It's difficult to demonstrate because they can't work on the oven when it is hot, but they don't have time to sit around while the oven gets up to temperature plus half an hour to see the controls heat up. Oh well, hopefully we'll get an excuse to replace it sometime soon.

I had this problem on an old oven with cooling fan for controls. It wasn't the thermostat but the thermocouple - that's the bit that connects into the thermostat and actually tells the thermostat the temperature. Is that perhaps "the other component" that was changed?

Hmm - I don't think they called it a thermocouple because I think I would have remembered that. Looking at the parts list, what I thought was the 'thermostat' was probably the thermal cut-out.

The other component which I have forgotten the name of seemed to be something that they didn't normally have to replace. It was something to do with controlling whether or not the cooling fan came on but I forget exactly what! We've got a new one anyhow, so I guess it probably wasn't that.

It sounds like the fan is cutting out too early, perhaps due to a faulty thermostat.

I have an AEG oven with a little ventilation slot, and the fan keeps running for a considerable length of time after I've stopped using the oven. By then it's just warm to the touch.

Yes, I think it's cutting out too early, but after two new thermal cut-outs (and the new thingamajig), the engineers seem to have run out of things to replace, and don't seem to be able to tell me how long it should run after turning the oven off, so I'm stuck.

What model oven is it? I've got a BP730100M which I have other problems with the control panel, but I've never noticed it getting hot.


There is no run on fan at all on mine once I turn it off from about 200C.

It's this one B4101-4 (stainless steel)
