How to Troubleshoot & Replace Ge AP2030108 / WB36X10131 Cavity Lamp (Interior Light)

Replace the bulb. 

Purchased a bulb from you and installed it. 

Replaced it. Only problem was microwave weighed 60 lbs. and you have to unplug to remove from cabinet. Need extra person. Instruction I found on internet for my model not quite match , but close enough. Instructions say to use t25 to Remove, mine was t15. Light mounting was different but easy. 

Had to remove it from built-in cabinet. Also found out you need a torx screwdriver to remove the screws. Microwave was heavy and had adjustment support screwed into it to fit the space. Besides having to go the hardware store to get the screwdriver, it took all afternoon to replace one bulb. I under stand why GE has it set up this way but it was still a big pain to do. 

This was an interesting repair. Emerson uses torx-head screws to limit access to the interior. Luckily, I had a screwdriver that fit these star-shaped heads! Once the cover/shield was removed it took a little time to figure out what I was looking for, but I found the light bulb and proceeded to remove the fitting. Going on AppliancePartsPro, I found what looked like it would work, but the model matching software indicated that it would not. The photo on the webpage looked exactly right, but the wattage was 5 units higher than the original bulb. I decided to take a chance. The part came, I took the microwave apart again and replaced the bulb and, wow! It's bright again! The increased wattage may affect the microwave's power, but probably not much. Since the unit is over 13 years old, I figure the microwave will probably fail due to something else. I appreciate that you show photos of your parts. Without that feature, I would not have been comfortable enough to try a part that was similar but not exactly the same. It fit perfectly and works fine! Probably last a long time, too!

Customer service was very good, as for instructions on how to do it. Thank you so much. By the way you don't need a certified GE person to do this job you just need the time and patients. To GE incredible that you can do a better product. 

Watched a u-tube video on how to replace blown light bulb in my microwave. I got the light bulb from you and replaced the blown bulb the same day. All went well. 

I found the best price on the internet with Appliance Parts Pros, ordered the new bulb. It took me about 20 minutes to replace.
