Neff B1641 oven not heating up.

Neff B1641 not getting hot in any mode.
Removed top cover and checked out control module, and found that the relay for the heater eliments is not switching in.
Not sure what the nominal resistance of the thermocouple is but is giving about 540 Ohms (I am assuming it is a thermocouple on the square plug next to the heating element output.)
Anyone any ideas or resistance readings.
Cheers.
Steve.

    Eureka!!!!!! Done it!



    Found a dry joint on the control unit. If you take the controller out of the oven and then remove the printed circuit boards, there are two boards soldered together- resolder all the little joints where the boards meet. This must be a common fault, as they look very flimsy and flex each time you push the buttons on the front display.



    Obviously not to be undertaken unless you know a little bit about what you are doing!!!!



    Don't forget to fully isolate the oven from the mains first. 240V.a.c is present on this board so beware! Torks drive screws are present- so you also need to have a Torks set.



    Hope this helps someone out there.



    Regards,

    Steve.

    P.S. These should have been called Naff Oven appliances rather than Neff!!!

SOURCE: 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.

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.

Fan oven not heating up to temperature

If the fan is working o/k then it is probably the element that has failed.
This is to be found at the rear of the oven compartment behind a removeable cover.

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.

Oven not heating up! Fan works. Grill works OK. Don't know what model it is? It's stainless with black hideaway buttons. It's a built-in Neff single oven. We had just roasted a duck, everything was...

Hi, The main problem I find with this fault is the fan element has blown. This usually cannot be seen without taking the fan cover off inside the oven. Thanks.

Problems with the fan on neff b1641 oven

Hi, from what you describing it can only be either the oven element (located behind the back plate inside the oven, hold by 6 screws, 2 at the top, 2 at the bottom and 2 on the sides). Switch off the cooker, remove this panel and have a look at the element, looking for unsual bends, corrosion, or burn marks. The other possibility is the safety stat located near the element connections at the back of the oven. Pull the oven out, remove the back chassis panel and inspect the stat.

The oven fan element has failed, you need to fit a new one.

Refit element cover.
Job done..
Make sure you have power off to oven before you start.
Plz rate my solution.

Neff B1641 Switched my oven on the other night it made a noise like a fuse blowing and went dead no lights no controls whatsoever i checked the power and i traced it all the way to the control panel...

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.
