Electrolux EOB3400 not getting to temperature

[philipgreg]

I’ve just moved into a house which has an Electrolux EOB3400AOX built in fan oven, Part number 949716231-05. It takes a long time to heat up.

The thermostat light is on all the time so it’s demanding heat.
The fan is running, sucking air in from the oven.
The element is heating up the back panel (which I’ve not taken off yet) – I will check the resistance once I’ve got the cover off, what should it be?
The ventilation fan is blowing cool air out of the top of the door.
I can’t feel any heated air being blown around the oven, I also can’t see the vents this should be coming from. Could they be blocked with grease or are there any other possibilities I’ve not thought of?
Thanks

I don’t know this specific model but usually with fan ovens the air is drawn into the grill in front of the fan and blown out around the sides. You certainly should be able to feel it blowing hot air around.

are you sure you have it on the correct setting

True fan oven

manual also lists moist fan baking which seems to have a lower temp

does the lamp never go off , try setting a low temp say 75 degrees and see what happens

most of the time these elements either work or they dont but occasionally we get one that cuts out when hot

Ok, so yes it’s definitely set to tru fan oven the picture of a fan with a circle around it.
I have taken the backplate off and the fan is spinning and the element is getting warm but not anywhere near glowing red.

The resistance of the element (disconnected from wires) is 72 Ohms and it is a 2400W element. By my calculation this should be 22 Ohms so a 72 Ohm element would only produce 734W .

Is my reasoning correct? Seems like a new element is required although not sure why it would be a bit higher resistance unless of course it’s always been rubbish due to a faulty manufacture.

very unusual for an element to gain resistance

but if your meter is accurate it will struggle to get to temp at those wattages

Final post, I ordered a new element, checked the resistance before fitting and it is 23 ohms. Old one is definitely 72 ohms.
Fitted it and it works like a dream, heats to 180C in about 5 mins.
Thanks for your help everyone.
