Description
Restore proper door-light and door-alarm functionality in your refrigerator with the genuine OEM LG Push-Button Door Switch (Part 6600JB3007E). This switch is designed to activate when the refrigerator door opens (light ON) and deactivate when it closes (light OFF). Because door-sensing issues may also relate to wiring, hinges or door alignment, please check with your maintenance technician to confirm this part number matches your appliance’s full model number and that the problem has been correctly diagnosed before ordering. partselect.com+1
Features & Benefits
-
OEM-quality push-button switch designed for direct replacement in compatible LG-brand and Kenmore refrigerators, ensuring proper fit and performance. LG Parts+1
-
When the door opens, the switch is released and the interior light activates; when the door closes, the switch is pushed in and the light turns off — restoring normal door-light operation and helping preserve food by maintaining a dark, cool environment when the door is shut. partselect.com+1
-
Helps ensure the door-open alarm (if your model has one) functions properly by restoring the door-switch signal to the control board. partselect.com
-
Simple installation: generally accessible behind the door hinge cover or door frame; a qualified technician or experienced DIYer can complete the replacement in short time when the correct model is matched.
-
Cost-effective repair: Replacing this switch can eliminate symptoms like lights staying on, lights not turning on, or the interior alarm sounding erroneously — often without needing major component replacements.
Common Symptoms That Indicate Replacement
-
The interior refrigerator light does not turn on when the door opens.
-
The interior light stays on even when the door is closed (leading to higher energy use or warming of the fridge).
-
The door-open alarm (if equipped) triggers even though the door is fully closed.
-
Door hinge or frame seems fine but wiring or switch diagnosis points to a faulty push-button switch.
-
Visual inspection reveals a broken, stuck, or non-operational push-button switch (e.g., button stuck inwards, cracked housing).
If any of these symptoms appear, have your maintenance technician verify the switch, wiring and door alignment before ordering the part.

Compatibility Notes
-
Matching the full model number of your refrigerator is essential: even though many appliances look similar, slight differences in door hinge location or switch orientation may require a different variant.
-
A non-functioning door switch can mimic other problems (interior light bulb failure, wiring fault, control board issue), so technician confirmation helps avoid unnecessary part replacement.
-
Installation typically involves unplugging power, opening the door, removing hinge cover or frame trim, unplugging old switch and installing the new one—ensure you follow safety protocols.
-
After installation, check door closure, interior light operation, and alarm/door-open functionality (if applicable) to confirm the replacement solved the issue.
