Yes, there is a light on the right hand side of the microwave (looking at the control panel). It is located directly behind the control panel and may be seen with a flashlight looking inside the door through the perforated metal housing. Four special hex-with-stem screws must be removed from the cover to access it, along with one standard Phillips head screw on the side. Once the screws are removed you must slide the cover toward the back about 1/2" before it will be able to tilt up and be removed.

For safety reasons make sure to unplug the unit and allow it to discharge before removing the cover. Also make sure to not touch anything you aren't intending to work on - it could be carrying power from the capacitor, which is like a battery, and might not be discharged while you are poking around inside.

I am currently seeking out a replacement lamp for mine. I could not find one at any of the local hardware stores as this has a proprietary base and the bulb is not removable from the base. I will be looking on ebay and elsewhere.

Frigidaire gallery microwave light stays on and internal fan stays on

Good Afternoon Friend, thank you for your post!

I see that the internal light and fan continues to run on your Electrolux microwave with the door close. This sounds like the issue is related to a faulty door switch. I am fairly confident that an authorized service agent will be able to restore your microwave to its normal operating condition. You can often locate a qualified service technician on the manufacturer website. Hope this helps! - Z

There is an internal fuse. Be careful high voltages present even if the microwave is unpluged.

Good luck

Internal light does not come on

Relay RY1 on the control circuit board has probably failed.

It's the relay closest to connector CN1, the 7-pin connector.

'Samsung smh7174wc' will not cook

It is probably more than a fuse which has gone on the microwave and because of the lethal voltages involved with this appliance plus the real risk of a damaging leak unless you have a microwave leak detector and a technical background i would advise finding a qualified technician. Good luck.

My microwave quit working

You have obviously damaged the circuitry. Service is expensive. Unless the unit is under warrantry my advice is to replace the oven. The newer ovens are very reasonable and have great features. Check Home Depot.

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.
