I have a whirlpool double oven. At first when I turned the oven off the cooling fan cooled the unit for aroun 15 minutes. Now the cooling fan is on when the oven is on but when I turn the oven off the cooling fan stops. The 3 thermostats have been changed but it is still the same. Any ideas?

Hi - It's nothing to do with the Thermostat - there is a small circuit board inside the back casing with a timer circuit on it - they're fairly reliable - check it isn't disconnected - they can be easily repaired if you know someone with electronics knowledge - if you have to pay it would be cheaper to buy a circuit board
