Neff U1721 fan oven dead. Where do I look next to trace the fault? I've replaced the blown element and replaced the blown thermostat which is located on the the fan panel. I removed the fan motor and bench tested it which runs perfectly when power applied. All wires look clean and not burnt. What component should I next test or replace? Is it possible for the control panel circuit board to have been damaged when the element burnt out? Thanks in advance for your help and advice, robert
This could all so be the timer

Nefffan oven element video1, If the fan motor in the back of the oven is going round andthe temperature light is on (normally little red light), but there is no heatthen you will probably need a new oven element, these are generally very easyto fit and readily available from our website these can be tested with aelectric meter.
To gain access to the NEFF element you willhave to remove the back plate from inside the oven. Once removed you will seethe fan and element, if youlook closely at the element you willprobably see a small hole burnt in it where it has blown. Sometimes howeverthere is no evidence of a fault but the element is open circuit ie:broken inside the element casing, either way it will need replacing. Someelements will are fixed from inside the oven and some are held in place by nutsfrom the rear of the machine.
2, If your NEFF fanoven is getting warm but takes a very long time to cook or is burning the foodmore on one side than the other, then you need to check if your oven fan motor is working you willsee 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 thenyou need To replace the oven fan motor is a little moreexpensive and a bit more involved.
3. If you have the opposite problem ie: your oven is over heatingand 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: noheat 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.
You first of all need to determine if you have got power to the oven.
Locate the point where the mains cable enters the oven, and remove the terminal cover, and test for voltage there.
If voltage present, then it could well be the main circuit board is faulty
It may not be obvious what part is faulty, but you must jhave a meter to check through the circuits.
Hope this helps.
