I have a faulty Neff built in oven (B1422E0GB/03) – I think

Customer Question

I have a faulty Neff built in oven (B1422E0GB/03) – I think series 2.
It has just decided to stop. There is a faint flicker of life when I turn the control knob, the temp neon light flickers as I move between selections. Otherwise totally dead – no internal light, no fans. The only other clue is I thought I smelt electrical burning just before it died.
I have a pair of these ovens (side by side – the other is still working) so I have changed the clock, the cooker selector switch and a small circuit board (control module) on the top of the oven but it has not resolved the problem.

`Hello, my name is George..

Under the top cover of the appliance is a thermal limiter.. Please check this for continuity.. If it has no continuity then this will be the cause of the lack of power, however, you should also then find the reason that the thermal limiter has opened.

Kindly be patient whilst awaiting any responses from me as I'm not constantly available.

Hi George

I think I have resolved the issue.

I have borrowed a multimeter and traced the fault to a burnt out cable in the wall switch.

Not sure why this has burnt out so for now will replace the cable from the wall to the oven.

Not sure why the temperature neon came on as I assumed power was OK.

If the cable burns out again I will need expert help.

Thank you for letting me know Paul... The cable that is burnt out, is it on the cooker side or the mains side? Also, was the cable on the neutral or the live side?

Hi George

It was the neutral wire from the switch to the cooker.

It has also damaged the switch so I shall replace that.



Expert:  George-Allsorts replied 2 years ago.
Ok Paul, this is common.. The neutral wire will have not been screwed in tight enough.. This causes the connection to heat up and eventually burn out.

Replace the wall switch, cut off the first 2 inches of the cooker cable and re-wire it... This will sort you out.. you will NOT need to replace the whole cable.

Make sure the connections into the new socket are tight enough.

Hi George

I was thinking of doing that with the wire.

I have just noticed that the wall switch was just a 13amp fused spur. Probably was OK but I will replace with 45amp switch.

You are very welcome Paul..

If you have any further problems, give me a nod.
