On the GE overhead microwave there are 2 bulbs on the bottom. I need to know what bulbs to buy?
Just look at the bulbs that were in there, they will have the correct info. If you dont have them, check your owners manual and if you dont have that for some reason, google the model of your microwave online and get a manual to look for the bulbs.
@oostdyke like @cam2363 said it’s easiest by removing the old bulbs and then matching those with the replacements. I have two GE Microwaves and both use WB36X10003 bulbs. This will definitely depend on your model.
