Interior lights not working but refrigerator cools normally.

Safety first: Unplug the refrigerator before replacing light modules or switches.

Steps to restore lighting:

• 1. Check door switch: Press the door switch by hand; if the display or fans respond but lights do not, the switch may still be suspect. Test for continuity and replace if faulty.
• 2. Replace light module: Remove the light lens and replace the LED light module or bulb with the correct Frigidaire part.
• 3. Inspect wiring: Ensure the light harness is connected firmly at the module and, if accessible, at the control board.
• 4. Control board: If new lights and switch do not fix the issue, the LED driver on the main control board may have failed and require board replacement.
