Tappan Oven Is Not Heating Evenly — Causes And Solutions

Below, we have listed the possible reasons why your Tappan oven is not heating evenly and what to do about them.

1. The Racks

If the racks in your oven aren’t properly placed, it could cause your oven to heat unevenly. Open the oven door and look at the racks. Make sure the sides of the racks are on the same level. If the racks aren’t leveled, reposition them. If the racks appear to be warped because of use, replace them.

2. Oven Isn’t Leveled

If your Tappan oven is not heating evenly, it may be because it isn’t leveled. Open the oven door and place a leveler on the center rack.
