I looked at the above Neff integrated microwave oven that when started counts down but there’s no power to the fan or HV side and the turntable turns slowly.
There’s no insulation fault, the monitor fuse is OK and the door switches test and operate as they should.
I am pretty sure it’s the PCB but before committing to changing it wondered if anyone else has come across this problem and if hey can confirm it is the PCB.
Thanks.
