Interior light stays on even when the door is closed, causing overheating.

Safety: Unplug the unit before adjusting the door switch.

Steps:

• Locate door switch: Typically found along the cabinet frame near the top or side, actuated by the door.
• Check door alignment: Ensure the door closes squarely and fully depresses the switch plunger.
• Manually test switch: Press the switch in by hand with the door open. The light should turn off. If it does not, the switch or control is faulty.
• Replace switch: Remove the switch from the cabinet (usually clipped or screwed) and install a new Frigidaire door switch.
• Control board check: If a new switch does not resolve the issue, the control board may be misreading the input and should be replaced.
