The light bulb in your refrigerator may not be burned out. A new light bulb in a refrigerator should last from 2 to 5 years. If a light bulb in your newer refrigerator is not turning on, it might be another issue.

TIP: If there are multiple bulbs in your refrigerator and only ONE bulb is not working, then assume it is burnt out and replace the bulb with the same type and rating. Refrigerator bulbs are typically a size E26/A15 bulb and either 30W, 40W, or 60W depending on the model. If ALL the bulbs are not working, then assume something else is wrong.

Check these things first to be sure the bulb is actually burnt out or something is not right with the refrigerator…

Have The Refrigerator Doors Been Left Open?
On many refrigerators the lights will turn off after 8 to 10 minutes after being left open. If the refrigerator doors were left open, close the refrigerator doors and wait up to half an hour before opening the doors. So, if the doors were left open, the lights will not work for some time, so replacing the light bulb(s) is not necessary. Give the refrigerator some time to cool down so the sensors begin to start working again. The refrigerator should resume normal operation after 30 minutes or so.

Have The Refrigerator Doors Been Removed And Reinstalled?
If you have removed the refrigerator doors for repair or cleaning, this can cause the lights to not turn on. Be sure the doors are aligned properly and that the wire harness is securely connected. If the wire harness is not connected, the refrigerator thinks the doors have not been closed and the lights will not turn on. Check to be sure the wire harness is connected and the doors are aligned. The wire harness should be located on the top left refrigerator door. Here is a generalized picture of the wire harness below…

Is Sabbath Mode Activated?
Some new refrigerators have a setting called Sabbath mode. THis mode will cause the lights in your refrigerator to not come on. Using your refrigerator display panel, go to Sabbath Mode setting and turn it off. Find your refrigerator manual here to turn Sabbath mode off.

About Refrigerator Sabbath Mode
Sabbath mode stays on for 85 hours once it is activated and after 85 hours it will deactivate automatically. When the refrigerator is in Sabbath mode, the buttons, the display, and the internal lights do not function. The refrigerator and freezer, however, continue to cool. Controls must be unlocked before activating Sabbath mode.

How To Activate Sabbath Mode
Press and hold the Door Alarm button and the Water/Ice button at the same time for 5 seconds.

How To Deactivate Sabbath Mode
Press and hold the Door Alarm button and the Water/Ice button at the same time again for 5 seconds.

TIP: On some top mount refrigerators the sensor is in between the doors. If the doors are both open at the same position then the refrigerator will think the doors are closed and the lights will go off.
