Hi. I’m looking for an oven door seal for model Beko QIF21X Oven but can;t find one anywhere. Please help,

Beko OIF21300B Oven does not come on but power is present and ECB is not tripped. Fault was intermittent but is now always present. The oven would come on for a few minutes heating up and then cut out or the oven lamp would flicker briefly on startup and the cut out.
I have taken oven out of enclosure and opened up back and top cover. 240 V is measured across internal side of terminal block.
The thermostat switch opens and closes ok.
The oven elements on top and at fan are not open circuit and continuity check ok.
The thermal safety cut out switch continuity is ok.
The fan winding checks ok on both fans.
The digital timer display is working and I rest it before attempting to turn on the oven.the timer is on manual mode of operation.
The oven function controller I have taken resistance reading across terminals while changing settings and opens and closes switch settings.
That leaves the pcb of the timer module.
I need a circuit diagram of the module PCB and a wiring layout for the oven to investigate further.
Is there a relay involved?
Any help or suggestions gratefully received.
Regards
Ross

I’ve got a Beko BBIF12300B oven, and it works fine for the first 15-20 minutes, but then it just suddenly cuts out completely. I have to wait a while before I can turn it back on. I’ve watched some of your video and my conclusion is that I have a faulty selector switch but I don’t know how to inspect it for any sign of burning. Could you please help me what’s causing my oven to switch off unexpectedly?

I’ve got a Beko BBIF12300X oven, and while the main oven seems to be working, the grill element simply isn’t heating up at all. It’s making grilling impossible. What are the common reasons for a grill element to stop working on this model and how can I fix it?
