Is it safe to keep using?
Yes. A failed interior light does not affect cooling or food safety. The unit is fully safe to use while you arrange repair.

Yes. Unplug for 5 minutes and restore power. If the light failure is due to a brief control board fault, this may restore it.
When to stop immediately?
Stop if you notice: Light failure is accompanied by loss of cooling, Burning smell from inside the cabinet near the light area.
Symptoms You May Notice
Interior is dark when door is opened
Opening the refrigerator door reveals a completely dark interior — no light turns on despite the unit appearing to function normally in all other respects.
Light flickers before going out
The interior light flickered intermittently for a period before failing completely, suggesting a loose connection or failing LED module.
Only part of the interior is lit
Some LED segments illuminate while others do not, indicating a partial LED strip or module failure rather than a door switch or wiring issue.
Light does not respond to door opening
The light stays off regardless of how fully the door is opened, ruling out a sensor trigger delay.
Possible Causes
Failed LED module or bulb
The interior LED module or light bulb has burned out. LED modules in outdoor appliances can fail faster due to heat exposure and UV degradation.
DIY PossibleDoor switch stuck or failed
The magnetic or mechanical door switch that signals the control board to illuminate the light has failed or corroded in the outdoor environment.
DIY PossibleLoose or corroded wiring connection
Moisture in the outdoor environment causes wiring connections to corrode, leading to intermittent or permanent loss of power to the light circuit.
Requires ProfessionalControl board light relay failure
The relay on the control board that controls the light circuit has failed, cutting power to the light even though the LED or bulb is still functional.
Requires ProfessionalSafe Checks You Can Do
-
1
Confirm the unit is cooling normally
Use a standalone thermometer to verify the cabinet is holding its set temperature. A light-only failure with normal cooling confirms the issue is isolated to the light circuit, not a power problem.
If the unit is also not cooling, the light failure may be a symptom of a broader power or control board issue.

2
Test the door switch
With the door open, locate the door switch (usually a small button or magnetic sensor near the door frame). Press it manually with your finger and release it several times. If the light responds to manual actuation, the switch itself is the problem.
Clean around the door switch with a dry cloth — outdoor debris and moisture can prevent it from actuating properly.

3
Inspect the light module
If your model has a replaceable LED module or bulb, locate it inside the cabinet ceiling or wall. Check if it can be unscrewed or unclipped for inspection. A blackened or visibly burned LED is a clear sign of failure.
Take a photo of the module label before ordering a replacement to ensure you get the correct part number.
When to Call a Professional
Contact a qualified technician if:
- Door switch tests normally but light does not respond
- LED module appears intact but still does not illuminate
- Wiring connections show visible corrosion or damage
