Hi my name is ***** ***** First question ~ how old is it?
Do you have anything in the display?
OK first thing to check is that you have power at the wall outlet - do you have a multimeter or mains tester?
Hi, it appears the expert has been delayed in responding, I just wanted to see if you still would like assistance or if you would like me to pass the case to customer services to arrange a refund.
Should you wish to carry out with the troubleshooting, since we have checked the power source is not the issue, the next step would to to check the control switch (£37) and from there the PCB (£44), which is just a case of checking if your getting power to the circuit with a multi meter.
Should you wish to have an engineer attend to do this level of troubleshooting please advise of your postcode.
You need to remove the top cover of the oven and check your getting power to the PCB using a multi meter set to 240V.
From here you then need to trace the wire leaving the PCB to the function switch and check your getting power to the switch, when you set it to fan.
Once you know which modules of the oven are live we can look to narrow down the fault further.
Unfortunately this questions is taking up to much time for the amount paid, so will opt out for another expert to assist, but believe its currently under priced and you may struggle to get the level of assistance you require.
