Description
Ensure reliable lighting and door-switch operation in your refrigerator with the genuine OEM switch part 5309918806 from Frigidaire/Electrolux. This switch is used to turn the internal light on/off when the door opens or closes and also may serve as a door-position sensor in certain models. Because switch assemblies vary by model, year and configuration, please check with your maintenance technician to verify that 5309918806 is the correct part for your appliance’s full model number, and that the light or door-switch function really is the failed component before ordering. frigidaireapplianceparts.com+1

Common Symptoms That Indicate Replacement
-
The interior light does not turn on when you open the refrigerator door.
-
The light remains on when the door is closed, draining power or causing heat build-up.
-
You hear a click/see the switch physically hanging or mis-mounted when opening or closing the door.
-
The door doesn’t detect properly (for models where the switch impacts door-sensor functions) — e.g., control panel shows door open when it’s closed.
If you spot any of these symptoms, have your technician verify that the switch is the correct part (5309918806) and that the wiring, lamp/socket and door latch assembly are not the root cause.
Compatibility / Partial Model Notes
-
The part 5309918806 is listed for many Frigidaire/Electrolux built refrigerators as the door light switch. appliancerepair.homedepot.com+1
-
It replaces older/alternate numbers such as 5566451, 187200, 5308037962 in some literature. appliancerepair.homedepot.com
Because refrigerator models vary by door style, liner, hinge location and year of manufacture, you should verify your appliance’s full model number (usually inside the fridge on the service tag) before ordering.

Compatibility Notes
-
Matching the full model number (including suffix letters) of your refrigerator is essential — even if the old switch looks identical, mounting tab spacing, wiring or housing may differ.
-
Replacing the switch restores light/door-sensor operation only if the lamp socket, wiring and door latching mechanism are functioning properly. If those are damaged, the symptom may persist.
-
Installation typically involves shutting off power, removing the old switch (usually clipped or screwed into the door liner), disconnecting wiring, installing the new switch 5309918806, reconnecting wires, restoring power and verifying the light works as intended when the door is opened and closed.
