I have a Defy slimline 600 white oven. My food/ baked goodies either gets burned or doesn't cook completely. I was told it could be the thermostat. If it is, how do I fix it?
You pick up the phone, dial the number for your local service company and ask them to come and fix it. No point you even thinking of doing it yourself.
