Sub-Zero Oven Not Heating Up
A common problem mainly with old Sub-Zero ovens is they can take too long to heat up.
Slow heating of an electric oven can also indicate a variety of issues with the appliance.
The likely cause of the oven taking too long to heat up is hot air leaking from the oven.
Possible Solution(s):
Damaged oven door seal: The seal is attached to the oven door and ensures that when the door is closed, it forms an airtight seal.
This allows the oven to trap all of its hot air. When the seal is damaged, hot air escapes, and the healing process is delayed.
Oven door hinges that are damaged: Hinges allow the door to open and close easily while remaining perfectly aligned with the rest of the appliance.
When they become bent or broken, the door is unable to close securely, preventing the oven from trapping heat inside.
As a result, hot air escapes and the oven takes an inordinate amount of time to reach cooking temperatures.
If you have found the Sub-Zero oven to be properly sealed, then it’s likely to be a result of a power supply issue, faulty main control board, or heating element being worn out.
If that’s the case best to contact an appliance repair technician.
