I have a Neff double oven FD8403. The main oven no longer

Customer Question

Hello I have a Neff double oven FD8403. The main oven no longer heats, nor does the internal light come on. The top oven still functions as normal. I thought the problem might be just the element, but with the light not working I'm thinking it may be more serious.
Do you have any ideas what the problem might be?Many thanks,

Do you have the model number please.

Also is the clock set or is it flashing?


Customer: replied 9 months ago.
It’s a Neff U1452N3GB /05
The clock is set and top oven functioning normally.

Thanks for that.

In this case then if the clock is set then its more then likely the thermal cut out safety thermostat on the back at fault.

You need to remove the oven from the housing and turn the power off.

Then remove the back panel and from there look at the back of the oven cavity.

Near the fan motor is the thermal cut out.

It will have 2 wires going to it.

You need a multi meter to check this so test it for contonuity.

If faulty then the thermal cut out will need to to be replaced.

The part number for it if you want it is 00057895

So check that out if you can as if the lower oven isnt coming on then its more then likely the thermal cut out at fault here.
