I recently tackled a repair on my GE microwave (model JVM1440BD003, manufactured in 2003) to replace the light bulb sockets for the under-microwave lights. Since one socket was failing, I decided to replace both at the same time to avoid future issues. I used two WB08X10016 light sockets, which are the correct OEM parts for this model.
The process started off smoothly thanks to a helpful installation video on the website. It made the job look straightforward: remove five screws to drop the bottom panel of the microwave, then remove one screw per light bulb socket to take out the old ones. That part was indeed easy and took just a few minutes with a Phillips screwdriver.
However, things got tricky when I tried to disconnect the wiring harness from the old sockets. The connectors were stuck—likely due to the microwave’s age (over 20 years old!). After some struggle, I realized the wiring harness itself was in poor shape and needed replacing. Unfortunately, finding a new replacement harness for such an old model proved impossible; I checked multiple parts sites, and they were all out of stock.
Thankfully, I found a used wiring harness (part number WB18X10193), which turned out to be a lifesaver. With the new harness in hand, I was able to connect power to the two new light sockets without further issues. The replacement sockets fit perfectly, and after reassembling the microwave, the lights worked perfectly!
Overall, the WB08X10016 light sockets were a great purchase, and the installation process was manageable with the right tools and parts. However, I’d caution others with older microwaves to check the condition of their wiring harness before starting this repair. If I hadn’t found a used harness, I might have been stuck. For a 2003 model, sourcing parts can be a challenge, but with some persistence, this repair saved me.
