Neff U1721 fan oven keeps tripping fuse within 60 sec I replaced Element, as was not heating up before

The Original Thermostat Made a loud Bang and wire melted. I replaced the Thermostat but then still no heat. I figured the element blew. so I have replaced the element and now it warms but the fuse blows within 60 seconds. could this be a faulty thermostat??

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.

Common Heating faults Neff U1721 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.

Lower oven not heating up everything else is working fine

hi, we have had the same problem. You can order the element from many places online, the cheapest is about £25 ranging up to £60 from neff themselves. Fitting it is ok the hardest part is getting the fan off to change the actual element. However, be warned, we are now on our 4th element and it just went again last night. Neff deny that this is a known fault that the elements keep going. However, at least 10 of our neighbours have had the same problem with their oven too!

Neff U1721 Double Oven - No Heat

If the fan is running then it is unlikely to be the clock/timer. Yopu need to check if there is voltage to the element but you MUST be careful to avoid an electric shock. There is sometimes a thermal cut out in line with the supply from the thermostat and that would need to be checked. If all OK the thermostat is the likely offender
