You can download the owner's manual here.

If the owner's manual doesn't cover it and there's no obvious cover on the side or rear, you'll have to remove the outer wrapper.

See these files:

The light will be located on the right side in the air duct attached to the magnetron or on the top of the oven cavity.


Most bulbs can be matched up at hardware stores, home improvement centers, and places like Wal-Mart or even large grocery stores.

You know how when you turn on a regular light bulb and it burns out with a bright flash? What happens is that when the filament burns out, it breaks and bounces back and hits the other electrical post and basically shorts out causing that bright flash. Sometimes, when 1 of the light bulbs in the microwave burned out, it shorted out, and caused the circuit-board trace to burn up. (This is not just conjecture; I've seen it.) If that's the case, then you would have to replace the main control circuit board. A rather expensive repair for no lights. BUT BEFORE YOU DO THAT, get an ohmmeter and check your new light light bulbs and make sure they are really good. Also, if you can, get a bright flashlight and check the light bulb sockets in the microwave (unplug it first). Check for possible corrosion or signs of arcing on the center electrode of the socket. If that's the problem, you might be able to use a small screwdriver to scrape off the corrosion of the socket (make absolutely sure you have your microwave oven unplugged before you do that!).

How to replace burned out light bulb


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

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.

Have an installed GE Microwave jvm1870 with a burned out oven bulb. Have replacement bulb but can not see how to get to the old bulb to replace it.


From the owner's manual:

Cooktop Light/Night Light

On models JVM1850, JNM1851, DVM1850 and EMO4000, replace the burned-out bulb with a 120 volt, 40-watt incandescent bulb (WB36X10003), available from your GE supplier.

On models JVM1870, JVM1871, JVM2050 and JVM3670, replace the burned-out bulb with a 120 volt,
20-watt halogen bulb (WB36X10213), available from your GE supplier.

To replace the bulb(s), first disconnect the power at the main fuse or circuit breaker panel or pull the plug.

Remove the screw at the left edge of the light cover and push on the right edge of the cover to open.

Be sure the bulb(s) to be replaced are cool before removing.

After breaking the adhesive seal, remove the bulb by either gently turning (for models JVM1850, JNM1851, DVM1850 and EMO4000) or pulling straight out (for models JVM1870, JVM1871, JVM2050 and JVM3670).

Replace with the same size and type bulb.

Raise the light shield and replace the screw.

Connect electrical power to the oven.

Oven Light

Replace the burned-out bulb with a 120 volt, 20-watt halogen bulb (WB36X10213), available from your
GE supplier.

To replace the oven light, first disconnect the power at the main fuse or circuit breaker panel or pull the plug.

Remove the top grille by taking out the screws on top of the grille that hold it in place and sliding the grille to the left (opening the door makes grille removal easier).

Next, remove the light cover.

On some models, the light cover is located in the center of the top opening.

Remove the screw that secures the light cover and lift the cover off.

On some models, the light cover is located at the left of the top opening.

Lift the cover off.

Pinch the clips that hold the light socket in place and lift the socket out.

Remove the bulb from the light socket by pulling straight out.

Replace with the same size and type bulb, then replace the light socket and cover.

Replace the grille and screws.

Connect electrical power to the oven.

One surface light bulb on GE Profile microwave keeps burning out


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...

Light bulb burned out in microwave oven


Most likely you're going to have to dismount the microwave and remove the outside cover to get to the bulb. This is a fair amount of work but is not rocket science. I'm not famliar with your particular microwave, but it's probably that way. If it's any comfort to you, light bulbs are usually not covered by warranties or service contracts.

It won't hurt to run the microwave without a bulb.

Burning smell and light switch does not work


The controller needs to be repaired. We regularly repair these control board assemblies for only $32.50 nationwide, and that's much cheaper than replacing the board. For safety, disassembly and other info see http://tinyurl.com/yzjozk
