Whirlpool Microwave Light Bulb Not Working

Whirlpool Microwave Light Bulb Not Working. When one has to do without the light inside their microwave for a bit, it can make it difficult to use the appliance unobtrusively.

While it most certainly doesn’t prevent you from using the appliance altogether, maybe creating some midnight snacks, after all, that is no longer a possibility unless you risk turning on other lights in your house.

It isn’t nice having to rely on external sources of light in order to properly use an appliance so important to our daily lives either.

The light inside can also help one more accurately assess whether their food has been heated up enough or not rather than simply guessing.

When the light bulb of your microwave is not working, do not start troubleshooting by replacing the control board. It’s best to check the light bulbs, sockets, and wiring before even opening the control panels and getting a closer look at the control board and all its components.

When the whirlpool microwave light does not work, we discuss some of its problems.

Defective Light Socket

Before you replace a light socket, replace the light bulb. Replace the bulb even if it seems to work at first, but later stops working because it could be that the power is not reaching it.

If the light still doesn’t work and you know the bulb has power, use a multimeter to test for continuity in the socket. If there is no continuity, replace it.

Main Control Board Issue

Before changing the light bulbs on a light fixture, it’s important for one to first check that all the wires and sockets are intact.

If these parts are damaged or faulty, it’s vital that one replaces them with new parts.

To determine if there seems to be a problem within the wiring of your specific make of lamp fixture, you could test whether its control board is sending enough electricity to the bulb sockets using a multimeter.

However unlikely this may sound if the control board isn’t sending enough voltage to the bulbs/fixtures, this may very well cause problems such as slow or dim bulbs.

Faulty Light Bulb

The light bulb might be burned out, but the parts surrounding it aren’t, and replacing those parts first is liable to either leave you with the same burned-out bulb in a brand new package or result in much damage to your house

that would’ve been avoided had you repaired the actual light instead of getting a replacement to light your way.


Is there a problem with the light under my microwave?

Aside from other factors like a loose wire or the microwave simply not working at all, one of the most common causes for microwaves going out is that the light itself may be burnt out.

First, check your microwave to locate the vents and remove its panel by unscrewing the screws from it.

Find the box containing the bulb located inside the microwave and take off its cover with help from a screwdriver.

Unscrew that old bulb and place a new one inside ensuring it’s securely in place. Then you’re free to test it out again.

Is it possible to use a microwave without a light bulb?

Most microwaves these days have a built-in light that turns on whenever the door is opened, or when the microwave is in operation.

While it’s not necessarily needed for it to function, it does make using your microwave a more pleasant experience and might make you less distracted while cooking your food compared to having to use a flashlight nearby. If you’ve noticed it burned out before, here’s what you do.
