When I switch on either the main oven, grill or second oven the fan gets really noisy after about 5 minutes which continues until about 20 minutes after it’s been turned off.
I’ve tried the two troubleshoots in the manual i.e check if it’s level and check the runners but no success.
Can you point me in the right direction as to exactly which part I would need to do this and where I can source it. Is it something I could do myself??
