Interior light does not turn on when door is opened.

Safety: Unplug the unit before removing the light cover.

• Check door switch: Test the reed switch with a magnet and multimeter. Replace if it does not change state.
• Inspect LED module: Remove the light cover and check for visible damage. Test for voltage at the light connector when the door is open. If voltage is present but no light, replace the LED module.
• PCB check: If there is no voltage at the light connector and the switch is good, the main PCB light circuit may be faulty and require replacement.
