Question about Microwave Ovens

My night light on my Panasonic SD297 OTR microwave won't shut off. I've pulled the two light bulbs out, it looks like one was burnt out, and I've replaced them. Same problem. Any ideas?

It's nothing to do with the lights themselves. It's a known problem with the lightboard on this model. Our motherboard has been replaced three times and our lightboard twice. It's not sealed properly and lets moisture up into the unit, frying the boards

It sounds like the control PCB uses a solid state relay to switch the bulbs on/off. These sometimes short out and won't switch off..
They need to be checked with an ohm meter before replacing at component level or replacing control PCB.

Panasonic NN-SD297 shuts off after 15 sec and refers me to the operating manual. What's wrong?


Don't believe it's anything you can repair if you don't have some knowledge about Microweves and doubt that manual can enlighten you. Your device is defective and should be repaired by an competent microwave technician.

Bulb replacement


Is it an over-the-range (OTR) microwave or a countertop microwave? If it's an OTR microwave, are you talking about the light(s) on the bottom of the microwave, or the one that lights up the cavity when you open the door or run the microwave?
If it's an OTR microwave, and the cavity light is burned out, you MAY be able to access it by removing the grill vent by removing the 2 to 4 screws above it. Then, depending on the model, either slide the grill vent to the left and pull it out, or else pull out the top part of it first. Then, if there is one, you may see an access cover behind the grill vent. Unplug the microwave, then remove the 2 screw that holds the access cover in place, and lift up and remove the cover. You should now be able to get to the light bulb.
If it's a counter-top microwave, you will have to remove the complete cover by removing the screws on the back, and possibly a couple of the sides. Note, 2 screws are special security screws to prevent the casual customer from fixing his own microwave oven! UNPLUG THE MICROWAVE FIRST, then remove the cover screws. Slide the cover back about 1/2 inch, and then it should come completely off. You should now be able to see the light bulb to change it. Then reverse the process to put the cover back on. I hope this helps.

How to change the light bulb


What kind of microwave oven is this? A counter-top model or an over-the-range microwave? Do you have a brand and model number? And which light bulb do you want to replace - the cavity light bulb, or the bottom light(s) of an OTR microwave?

Kenmore microwave nights light don't work.


That's a problem on the circuit board which can be repaired simply and inexpensively.

A YouTube video showing how to remove a typical over the range control panel assembly in under 5 minutes, is here.

Won't operate


see this steps and fix it. God bless you
No Lights or Power, Unit seems Dead First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.
Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.

I replaced the outside/night lights on my Kenmore microwave and the lights stay on. They are 3 settings, high, night and off and they do not cycle through, they are always on and won't shut off


This is a shorted relay on the control circuit board, which we normally repair for $39.95 nationwide.

At our Web site, you can get details of our service, plus we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

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.

The lights can can be inoperable or stuck on or stuck in "night light" mode. Sometimes this will similarly affect the fan operation or inside light, too.
