Freezer interior light stays on even when the door is closed, causing warmth near the light area.

Safety: Unplug the freezer before working on the switch or light.

Steps:

• Check switch operation: Press the door switch manually; the light should turn off. If it does not, test the door switch for continuity and replace if stuck closed.
• Inspect door contact: Ensure the door actually presses the switch fully when closed. Adjust the switch position or door alignment if needed.
• Control issue: If the switch is good but the light remains on, the main control board may have a stuck relay and require replacement.
