Hi most often when a problem like this arises the Thermistor, or the thermostat controller, is faulty. most often just the Thermistor, the actual little element that detects the temperature.This needs to be replaced first, and if the condition is not helped or fixed, then it is the thermostat controller that's faulty and must be replaced.

The Thermistor can be tested with an OHM meter to determine functionality or not, usually it is a few KOhms, it is faulty if Open circuit, Closed, short circuit, or a very high resistance, that will NOT change linearly with temperature change.

The parts are easily available via sellers on the internet.However to be able to obtain the parts one must have the manufacturers parts numbers, these usually are only available from the service manual. if wishing to DIY repair, then this manual must be obtained, usually again via the internet.

It may indeed be less expensive and time consuming to engage the services of a serviceman and get a "Quote" for the job, and go from there.

Common heating faults with Neff B1644 single 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.

HOW DO YOU REMOVE CONTROL KNOBS TO REPLACE THE ON THE NEFF B1451 OVEN


I have a Neff B1451 oven and have removed the thermostat knob just by pulling and wiggling it. Thats all you do. If then you want to rpelace the thermostat, there are two screws holding the unit onto the oven which are accessed by taking the silver metal shrouds off first.

The bottom (fan oven) of my Neff U1721 made soft bang noise and failed. The fan stopped, the oven light went out and the thermostat light. I replaced the burnt out heating with a new element with a 32.5...


The power to the fan and thermostat is the fault. You will need to trace wiring from these elements to power source and I suspect that where the power cord meets the oven is where you'll find the cause.
