Samsung Refrigerator: Light Not Working
Quick answer: A dark refrigerator is usually a burned-out bulb, a worn door switch, or a corroded socket, and on newer models a failed LED module or its low-voltage supply. Check the bulb first, then the switch, before opening up the control side.
- Unplug the refrigerator before changing the bulb or testing the socket.
- Use only the bulb type and wattage listed on the light cover; incorrect bulbs overheat the socket.
- LED light boards run on low voltage from the control board; never connect them to household power.
Why is my refrigerator light not working?
A dark refrigerator is usually a burned-out bulb, a worn door switch, or a corroded socket, and on newer models a failed LED module or its low-voltage supply. Check the bulb first, then the switch, before opening up the control side.

Most Likely Causes, in Order
1. Light bulb
Incandescent bulbs simply burn out, especially with frequent door openings and cold cycling.
How to check: Remove the cover and inspect the filament; a broken filament or darkened glass means it is dead. Try a known-good bulb of the same type.
Fix: Replace the bulb. (Difficulty: Easy)

- Refrigerator Light Bulb 4713-001172 — $12.05 · 54 models
2. Door switch
The door switch closes the light circuit when the door opens; a worn switch stays open so the light never comes on.
How to check: Press the switch with your finger; you should feel and hear a click. Unplug the unit, remove the switch, and test for continuity with the plunger released.
Fix: Replace the door switch. (Difficulty: Easy)

3. Light socket and wiring
Corrosion or a burnt socket prevents contact with the bulb base.
How to check: Unplug the unit and inspect the socket for green or black corrosion. Check that the wire terminals are firmly attached. Measure for voltage at the socket with the door switch pressed if you are comfortable doing so.
Fix: Clean the contacts or replace the socket assembly. (Difficulty: Moderate)

4. LED light module
LED assemblies fail as a unit or lose their low-voltage supply from the control board.
How to check: If some LEDs work and others do not, the module is failing. If all lights are dead and the door switch is good, check the connector at the module and the low-voltage output from the control board.
Fix: Replace the LED module; if there is no voltage from the board, replace the board. (Difficulty: Moderate)

Frequently Asked Questions
The light flickers or is dim. Is that the bulb?
A dim or flickering LED usually means the module is failing or its connector is loose; for incandescent bulbs, check the socket contact.
The light works but goes off after a while. Why?
Many models turn off the light after several minutes with the door open to prevent heat. Close and reopen the door to reset it.
Can a bad door switch affect cooling?
Yes on many models: the same switch controls the evaporator fan, so a stuck switch can stop the fan and cause poor cooling.
When to Call a Professional
Call a technician if the LED module has no low-voltage supply from the control board or if the wiring inside the door hinge is damaged.
