Hello, I hope you can help us out.
We have a Neff U1661 Double Oven. The top oven works OK but the clock and bottom oven are completely dead. This happened after the oven was switched on, there was a “flash” from the bottom oven and the fuse blew.
Once the fuse was rest there is power to the top oven but not the clock and bottom oven.
Any suggestions where to start looking?

Re: Neff U1661 No Clock or Bottom Oven
Almost certainly the fan oven element blowing – they live short violent lives. Timer being off is worrying, may well be damaged by the element shorting. It’s an expensive component as well…..b 🙁
Probably worth removing the rear panel (with the power off) of the oven to check – it’s usually pretty obvious and often quite spectacular when the element goes.
Regards,

That’s what I feared.
The fan element looks OK, but I guess I need to remove the whole oven to put a mulimeter on it?
Any suggestions on how I access the control panel? I suppose that is a Neff only supply and with 3 hungry kids it can’t be out of commission for long!
Thanks for your help so far.
Re: Neff U1661 No Clock or Bottom Oven
Can you post the full model number please, it will begin U1661 and have more letters/numbers after that. From the rating plate around the door normally.
From a quick check of a couple of versions the timer is around £75 ex carriage so if you’re unsure on how to check it, I would suggest an engineer to be honest. The repairs@ link below should provide one 🙂

The £75 Timer/Clock is fed by the £170 Control Unit. The chances are the fan element has blown and taken the Control Unit with it? 🙁
Re: Neff U1661 No Clock or Bottom Oven
Hi guys – you really know how to cheer someone up!
The full part no is U1661N1GB09. Other info on the plate is FD8208 HBB-AP59-8 5750.314191.
So add £170 for a control panel, plus the element, plus VAT thats going to be a £300+ repair and its only 4 years old. So much for a “quality” brand!
Quite happy to investigate the problem (I fix milking machines for a living) its just how to get access to the various bits. Presume I have to pull the oven out?

Correct 🙂

Re: Neff U1661 No Clock or Bottom Oven
It has been suggested by a local repairer that it is possible to bypass the clock? Any thoughts?

Pure speculation (over the telephone) perhaps by your local repairer I suspect? I wouldn’t think it would be possible, nevertheless some inspection needs to be made by a suitably qualified person to assess the situation?
I also am being speculative as to the possible fault based on the information given. Only expert inspection of the appliance can take it to the next stage though 😉
Re: Neff U1661 No Clock or Bottom Oven
Update.
I would appear the control panel for the main oven has failed. 🙁 There is no power output to the elements even with the clock disconnected and none of the display lights up.
The clock seems to work when connected to the top oven control panel.
There’s no visible signs of failure on the fan element and it has a resistance of 35 ohms. Not sure what this value should be but it will be quite easy to test with a separate lead.
Do I have to go to Neff for a new control panel? Unfortunately being without the cooker whilst the panel is repaired isn’t really an option.
Must admit I’d be reluctant to spend more than about £250 on this oven when you can pick up a new one for just over £400.
Thanks for your help so far.

I think you only real option is to call Neff in to check it out to be honest. If the repairs are costly then as it is only 4 years old, Neff may well give you a concessionary discount towards the repair. 😉 (i.e Meet you halfway on the cost?)
Re: Neff U1661 No Clock or Bottom Oven
Update.
After a removal of the oven, and swapping the control panel for the top and bottom oven, I managed to get the bottom oven working (but with limited functions).
Luckily a work colleague repairs printed circuit boards and he soon found the problem as a blown track on the input side of the panel. This supplies power to the lights, clock and also the thermostat relay. Our guess is that one of the lights failed, and shorted out, blowing the circuit.
A £20 repair fixed this and the oven is now working fine.
One thing I did discover is that Neff have a really good web site with exploded diagrams and part numbers etc. You can also check the cost of spare parts there.
Many thanks for all the help given here.
