Right bulb keeps burning out

Hi anything is possible being that you even replaced two different brands of bulbs. I don't think the wiring harness is the problem but like I said anything could be the problem. Might I make a suggestion. Why not replace both the left and right side bulbs with LED bulbs with the same base configuration. Maybe that just might be able to solve your problem. I would like to know if it does. It also seems that a lot of others are having the exact problem. Good luck.

please test this steps and fix it. God bless you

1. Light bulbIf your microwave light bulb is not working, perhaps it has blown. The first step is to replace the bulb and power on the microwave. If this does not correct the issue, the next step is to check the socket and wiring to verify if that is the problem.
   
2. Light bulb socket & main control boardIf your microwave light bulb is not working after the installation of a new bulb, check the light socket as well as the wiring to ensure they are properly operating. If these sources are functioning properly, the next step is to check for a faulty control board as a possible root cause to your microwave light bulb malfunction.
   

was the fan working before you replaced the bulbs? Did you check the old bulbs ie filaments broken....if two bulbs stopped working at the same time probability suggests that the problem was not the bulbs, especially since the breaker fired when you put in new bulbs.
Could be a short inside ...if you are not brave enough to take it apart and inspect better you take to be looked at ...better a fried microwave than a fried you...

You need to remove the top cover to access the bulb. That is the only way on most microwaves.

The only fix for it is to either buy another control board $300+ or if you are any good at wiring you can go the the hardware store get a manual toggle switch and install it under the microwave on the right hand side near the control area. But make sure the switch can handle the heat rising from the stove burners. We have about 120 of the microwaves on our properties and 6 of them have this issue. The relay internal switch becomes corroded and binds together from steam and boiling water. GE is JUNK.

Mine burned out within a month. Probably due to the poor design of the machine which forces you to slam the door to get it to shut.
My biggest concern is the under counter lightbulbs it has burned out in my kitchen over the last year. I wonder how much leaking this thing really gives off. Moving in a few weeks and will be throwing this cancer machine out.

Hello,
PLEASE UNPLUG YOUR MICROWAVE!
Remove the two screws that holds grill. They are located at the edge of the unit. Once the screws are out, rotate the grill forward from the top. It will pop right out.

Once the screws are out, rotate the grill forward from the top. The grill should pop right out.
Locate a small access cavity on the left.
Remove the screw that is located near the front of the microwave door.
Lift up the sheet metal floor to access the bulb. The bulb is located under the sheet metal "floor" on the left.
Place a flash light on the microwave floor and shine the light in the light area. This will help you see better when you replace your bulb.
Look for a small shiny reflector that hides the bulb. Use your two fingers to squeeze it a bit. Making sure not to bend it.
The bulb connection should come right out.
After you replaced the bulb, re secure the reflector and the sheet metal floor with the single screw. Test the bulb by plugging in your microwave.
Once you see that the bulb works. Unplug your microwave again and re attach the front grill. You are now done.
Hope this help in solving the problem, take care.....

I have the same problem. The left one burns out within a couple of hours use, the other one lasts a couple of months and is then gone. This pattern has repeated over 8 years. I replace them every now and then and then just go without until I get the urge again to fix it. Maybe smaller lower wattage lamps are worth trying...

If it doesn't have a door you have to remove the cover. Its likely a special microwave bulb and the socket will have to be replaced with the bulb. the bulb is built onto the socket.

They are indeed the same bulb, a 10W halogen. Care must be taken not to touch the lamp, as the oils from the skin will shorten its life. In many recent models, the oven must be removed from the wall (a two-person job due to safety concerns) and the cover must be removed. The manufacturers consider this a "technician-only" type job to lessen their liability. You can find helpful exploded view diagrams of both ovens and order the bulbs here: http://tinyurl.com/gv383
