Check you have power at the clock - the clock terminals not the relay. if not, there is a cut-out stat in the back. check this is still ok. if there is power at the clock then the clock itself may be faulty. you can bypass the clock by joining the terminals to the clock relay and get the oven going this way. another common source of problems is the terminal block where mains comes in and is distributed. these terminal blocks often burn out.

Common heating faults with Neff B1641 Single electric oven

For all Free appliance repair videos visit our VIDEO TUTORIALS 1, If the Neff fan motor in the back of the oven is going round and the temperature light is on (normally little red light), but there is no heat then you will probably need a new oven element, these are generally very easy to fit and readily available from our website these can be tested with a electric meter.
To gain access to the NEFF element you will have to remove the back plate from inside the oven. Once removed you will see the fan and element, if you look closely at the element you will probably see a small hole burnt in it where it has blown. Sometimes however there is no evidence of a fault but the element is open circuit ie: broken inside the element casing, either way it will need replacing. Some elements will are fixed from inside the oven and some are held in place by nuts from the rear of the machine.
2, If your NEFF fan oven is getting warm but takes a very long time to cook or is burning the food more on one side than the other, then you need to check if your oven fan motor is working you will see the blade turning fast if it is ok. if the element is heating but the fan motor is not blowing the heat into the oven then you need To replace the oven fan motor is a little more expensive and a bit more involved.
3. If you have the opposite problem ie: your oven is over heating and burning everything then you will need to replace your NEFF oven thermostat
4, A quite common and easily overlooked answer is if your NEFF oven is not working at all ie: no heat and no fan then the chances are that someone has put the oven timer into AUTO mode, simply put oven back to MANUAL mode and all should be working again.

My Neff oven is displaying the locked "key" symbol...does anyone know how to unlock please?

Locking the oven:
Using the main oven function selector, switch 3 x in
rapid succession from the 'off' position to the
oven light function and back again.
- s - is displayed.
The oven cannot be unintentionally
switched on, e.g. by children.
To release the oven, switch 3 x from
the 'off' position to the oven light.
- s - goes out.

Neff Circotherm Double Oven keeps blowing elemrnts. Ie. only works a few times then only gets warm

I assume that you are fitting genuine elements, as opposed to cheap copy ones..
Make sure the fan is working o/k as well.
You also need to check the temp is correct, for this you need to have a oven thermometer to check it with.
Make sure the connections to the element are o/k as well.
Hope this helps with your problem.

Turn the right hand button onto the ECS symbol. This is the cleaning cycle. Make sure you put some soapy water in the 'well' at the bottom of the oven. The oven is then steam cleaned.

Installing a B1641 oven

Providing it is just a single fan oven on it's own. then it will work fine from a normal 13 amp socket.
If it is a double oven, then it will have to be hard wired into a cooker control switch box, protected with a 30amp circuit trip or fuse.
Please rate my solution to your query.

It appears that the timer has gone faulty, possibly because of a short in the bulb holder, which probably explains why there is no display and the main oven not working. the top will still work as it is not controlled by the timer.
the solution hear would to be fit a new timer.

Neff oven B1641 child lock

I actually had the same problem and got the solution. Maybe its a bit late, but hopefully there will be somebody who find this useful as well.

Its not an error. The -5- indicates that the oven is "children protected".
- Put the left ON/OFF switch into its OFF position (the left switch)
- Turn it quickly 3 times: one click to the left and then one click back to right again [light position, Off position]
=> The message disappers.

If you do this again, the protection is switched on again.
