Possible Causes

Failed cooling fan, Blocked oven vent, Missing or misinstalled insulation

How to Fix / Troubleshooting

Safety first: Turn off power and allow the oven to cool before removing panels. Hot surfaces can cause burns.

Steps:

  • Check vents: Ensure that the vent openings above or behind the door are not blocked by trim, foil, or objects.
  • Test cooling fan: During a bake cycle, the cooling fan should run. If it does not, test the fan motor and replace if faulty.
  • Inspect insulation: Pull the range out and remove rear or side panels to inspect insulation around the oven cavity. Replace or reposition any missing or displaced insulation per the service manual.

Warning: Excessive heat at the control panel can damage electronics and should be corrected promptly.
