If it is like a microwave I had, you have to take the whole cover off. Just make sure it is unplugged before undoing the screws.

Can't figure out how to replace light bulb for model #721.66319

Sears Parts Direct lists the microwave, 72166319500 , as using the lamp, 6912W3B002L. This is available for $6.49 here: .

Unplug the microwave and wait a bit before starting to replace the bulb. To change the bulb, you first need to take off the entire cabinet (remove 4 screws on the back of the microwave and lift the part up). Then see the parts diagram on the page given above. There are 2 screws that hold the switch and bulb assembly to the frame of the microwave. I believe you should be able to pull the bulb housing down from the middle of the assembly and then push the unit up after replacing the old bulb with the new bulb. However, the bulb housing may have two screws holding it in place.

I hope this helps.

Where is the internal light bulb in the sears elite microwave convection oven

Hi there, I'm just running out the door, but came across your question after checking my solutions, and thought I'd give you a quick run through on where most lights bulbs on microwaves are usually located. One, they're either on the outer left side of the microwave (look for 4 phillip head screws within a cover approx. 3''wide x 4" long). If not there, then it's located on the top of the oven. Remember, before you remove anything...first, remove the plug from the wall outlet (receptacle) Again, you'll be removing 4 phillip head screws. Then, after removing the top cover (sometimes, you'll have to slide one way or the other, then lift) look again for the 4 phillip head screws within a cover approx. 3" W x 4" L. Remove this cover, unscrew bulb, and then replace with the same bulb. Its best to remove the bulb first, then take it with you to your nearest appliance store. This will help make it easier for the clerk helping you. Then, after you replace and secure all your covers and screws, and are completely can plug your oven back into the wall outlet.  Then turn it on to check and see if your lights back on and in operating order. I wish you the best of luck, and if you have any more questions regarding this matter, feel free to contact me again. Jim

Bought a home with a Kenmore UC MV, Model # 721-62643200 Ser # 311KM02070. There were no light bulbs in it, so I bought two GE Indicator 25 T-7 bulbs, for microwave ovens. These bulbs are 25w 120v. Upon...

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week or so.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan, cooling fan, turntable, and/or inside light operation, too.

Details of our service are at our Web site, along with a video showing how to remove a typical over the range control panel assembly in under 5 minutes.

Feel free to contact me directly with your brand, full model number and symptoms.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Kenmore 363.6367 internal light doesn't go on

I had the same problem! I was soooo frustrated! But, when my brother came to town, he took off the grill on the top of the micro hood, took out a few more screws, a plastic screen, another screw in the metal cover for the light and then reached in with his fingers to pull out the light bulb, we replaced it, then re-assembled it. It did take us about 30 minutes to do the job and you will need a phillips screwdriver, and a phillips screwdriver drill bit thing, but we were able to do it. I love having the light in the microhood again.

Kenmore elite microwave touch screen stopped working

Same thing happened to us. We just came back from Sears, where we bought another. Just for giggles, my wife suggested unplugging the old one and plugging it back in again. It works now. New one's going back to the store.
