Common Symptoms
- No cavity illumination when the door is opened or the microwave is operating
- No under-cabinet cooktop illumination on models using this assembly for surface lighting
- Flickering or intermittent LED operation
- Noticeably dim light despite normal appliance operation
- Light failure with the microwave display and heating functions still working
Check Before Replacing
- Confirm the appliance has power and that the display and other microwave functions operate normally.
- Operate the applicable cavity-light or cooktop-light control to verify whether the light is completely inoperative, dim, or intermittent.
- If the light is intermittent, observe whether gently closing the door or changing the light setting affects operation; do not force or disturb the assembly.
- Verify the appliance model's owner manual identifies W11443139 as the correct light assembly before ordering.
- Disconnect power before inspecting or replacing the assembly; do not remove the microwave cabinet or probe energized wiring unless qualified service personnel perform the work.
Pro Tip
Because this is an LED assembly rather than a generic bulb, verify the complete appliance model and connector/assembly application before ordering; a dark light with a functioning display does not by itself prove that the LED assembly is defective.

Part TypeMicrowave LED light assembly
ManufacturerWhirlpool
Appliance TypeMicrowave
Primary FunctionProvides LED illumination for the microwave cavity and, on some Whirlpool/KitchenAid microwave-hood combination models, the under-cabinet cooktop surface.
Installation Notes
- Disconnect electrical power before servicing the light assembly.
- Follow the exact access and replacement procedure in the appliance's owner or service documentation; access differs between cavity-light and cooktop-light applications.
- Do not substitute a generic bulb or LED module unless the appliance documentation specifically permits it.
- Reconnect any factory connector fully and route wiring as originally installed; do not alter the assembly or wiring.
- Restore power and test the applicable cavity and/or cooktop light after reassembly.
- Microwave high-voltage components remain hazardous even when the light itself appears to be a simple replacement; cabinet-level service should be performed by qualified personnel.
