Cooling fan does not come on at all...

Hi - if you still have your user manual I think you will find that oven have a time delay designed into the electronics for cool down purposes after the cycles completed. If it does shutdown after say 1.5hrs, it may seem a bit long but its actually doing what its designed to do, it should not be heating but circulating the hot air thru the oven.

We use to have a similar problem with our F & P BI600 wall oven - what we've done is have the door slightly ajar to quicken the cool down process until one day the fan ran continously - then I had it disconnected.

I hope this may help with your situation, if its running continously then its best to disconnect the cool down fan, the bake fan is normally on a separate circuit and not affected.

The oven cooldown fan will sometimes run for 10 to 15 minutes after turning the oven off. This enables the outer shell of the oven to cool down. Most ovens also have an inbuilt thermal overload in the outer shell. If the temperature in the outer shell gets too hot it will open circuit the oven power until it cools down a bit.

Your cooling fan may not be working. either the fan is faulty or its controling device is not switching it on it also allows the fan to run on after the oven has been turned off. its located in the wiring loom behind the switches. part 899661926761-1 costs £26

There is a cooling fan in the cabinet of the oven which is not working either the fan is faulty or the controling cut in stat is, The fan should run when the grill is selected if does not it is more likely to be the fan/motor at fault.

Your oven has a fan to draw in cool air at the bottom of the front panel, pass it around the case, and then blow it out at a position towards the top of the oven. This is a completely different fan that is at the back of the oven itself.

The cooling fan is necessary as the materials in modern ovens are kept light and thin as possible to save weight and manufacturing costs, however the flipside of this is that if not cooled by the cooling fan, they would be damaged by the heat inside the oven itself.

The cooling fan will continue to run for some time after the oven is switched off, because it will wait until the oven has fully cooled down before stopping the cooling fan.

thermostat

Could be caused by either of following;

1. Faulty thermostat.
2. Faulty thermal cut out switch. (controls power to cooling fan).
3. Faulty cooling fan (not fan inside oven).

Test thermostat by setting thermostat to low temperature like 60 oC. If oven gets much hotter then its a faulty thermostat.
To test cooling fan and thermal switch take oven out and remove top or rear panels to expose components.
When oven gets hot the cooling fan should turn on. If it doesn't then check to see if there is a mains voltage present.
If mains current exist but fan is not turning then replace fan. If mains voltage is not present then its the thermal switch.

Hi, I've had a similar problem with my electrolux EOB4633. I've replaced the "thermal cut out unit" and it's working now. Basically this unit switches on the outer casing fan ( on top in my oven ) to keep the casing from overheating. When the thermal cut out doesn't work it fails to switch on the fan and the casing overheats, the oven then cuts out completely until it has cooled down and the cycle starts again.

The bit to be replaced ( part no 8996619267611 ) is located on top of the oven, under the outer cover, just behind the timer & selector switch. It's a small ( 1inch long ) silicon sleeve with 4 wires coming out of it, just unplug the wires and replace it with the new one ( unplug/disconnect the power to the oven, or switch of the power at the mains switch first ), then remove the oven outer top cover ( all you need is a screwdriver ). You'll see the offending unit, probably tie wrapped to one of the wire bundles, quite easily - mine was blackened and charred.

Good luck!

After the oven is switched off, the after-run of the cooling fan is controlled by an electromechanical thermostat switch. The fan can switch back on, due to residual oven heat that accumulates within the oven's outer case and reactivates the cooling fan temperature switch. Considering yours is making buzzing sounds and activates on and off, the fan's thermal switch may have dirty contacts or just be defective and require replacement.

We have the same problem with our oven, AEG B2190-1.It started on on Christmas day[worst day of year]gets up to temperature after 10-15 minutes cuts out everything switches off until the oven has cooled down, The oven is only 18 months old. We have been told that it is a thermostat problem.
