Symptoms
- Interior light doesn't turn on when the door opens
- Light flickers before going out entirely
- Light works on one side but not the other in a side-by-side model
- Light worked recently but stopped suddenly
Likely causes
- CommonBurned-out bulb or failed LED moduleLike any light, fridge bulbs and LED strips eventually burn out from normal use.
- CommonFaulty door switchThe small button-like switch that detects the door opening can stick or fail, keeping the light off.
- PossibleLoose or damaged wiring to the light socketVibration over time can loosen a wire connection to the light fixture.
- Less commonFailed light control boardSome models with digital touch lighting have a small control board that can fail.
What to do
- Unplug the fridge before doing anything inside near the light fixture.
- Locate the door switch (usually a small button on the door frame) and press it a few times to see if it feels stuck or unresponsive.
- Remove the light cover if present and check whether the bulb or LED strip looks visibly burned out or damaged.
- Replace the bulb with the correct wattage and type specified for your model, or the LED module if that's what your fridge uses.
- Plug the fridge back in and test the light by opening the door.
- If the light still doesn't work, test the door switch further, since a stuck switch can be the actual cause even with a good bulb.
- Check for a tripped breaker or GFCI outlet if the whole fridge seems to have power issues alongside the light.

When to call a pro
