Reasons For Oven Making Buzzing Noises When Off

1. Cooling Period

The most common reason for an oven making a buzzing noise when off is the cooling period.

If you have been running the oven for a long period, the fan may continue to run when the appliance is off. As long as it is connected to a power source, the fan can keep running until the unit has cooled down.

How long will this last?

Each situation is going to be unique based on how much you used the oven during that time. In most cases, it will come out to be somewhere between 10-20 minutes.

If it starts getting past this point and/or is making too much noise then there may be another internal issue to contend with.
