If your whirlpool microwave display is not working, you may be feeling frustrated. It can be difficult to know what to do when something goes wrong with your appliance.

In this article, we will walk you through the steps that you can take to try and fix the problem. We will also provide some tips on how to prevent this from happening in the future.

Method 1: Check the Power Supply

The power cable and power supply are the first things to check if something is wrong with an appliance. If the screen has vanished completely and the buttons aren’t beeping anymore, it’s possible that your microwave was just unplugged or that a tripped circuit breaker is responsible.

Begin at the rear of the appliance. Is the cable properly secured, not loose or exposed at the base connection? Examine your wall socket. Is the plug firmly inserted into the wall? Does the end of the cable seem to be in good condition?

There’s a chance that the electricity was shut off to your outlet, not the plug. Check your breaker box. If one break is in the middle of facing in the incorrect direction, turn it “off” then back on to reset it. Then inspect your microwave.

In case everything else fails, try plugging your microwave into another outlet.

Method 2: Secure the Loose Wires

If the problem isn’t a power issue, then it’s likely that it’s inside your microwave display and control panel. To check this, take off the control panel and look “under the hood” to see if you can spot any issues that might be easily resolved.

Unplug the microwave from the wall to prevent receiving a shock when you access the wires behind the panel. Even after unplugging the device, the capacitor within will retain electricity for a long time. It may be necessary to perform a manual discharge, which should not be attempted without training and previous experience.

Find mounting screws on the top front of your microwave, which covers the front vent. Remove the screws and remove the vent from the door. Additional mounting screws secure the panel to the microwave cabinet after you’ve opened the door.

Take out the screws and pry open the panel. There will be wires connecting it to the microwave. Secure these wires firmly and/or disconnect and reconnect each wire harness. If there’s a loose wire, fix it by following these steps.

When all of the connections are secure, replace the panel and press it until the clips click. Then replace the mounting screws, vent cover, and mounting screws for the vent cover. After that, reconnect your microwave and give it a go. There’s a chance you just resolved whatever was wrong.

Method 3: Check the Temperature and Monitor Fuse

The temperature and the monitor fuse should be investigated if the microwave display is not functioning. Make sure they aren’t both blown out. Fuses are placed in various areas of each microwave type and manufacturer.

Method 4: Replace the Control Panel

If all else fails, consider replacing the control panel. In most cases, attempting to replace the entire panel assembly is preferable to try to figure out which little electric component went wrong and how to repair it. If you decide to replace the panel, be sure you find out specific information on this repair based on the brand and model of your microwave.

If you’re changing a microwave with an integrated oven, be sure it’s above the range. This will influence where your mounting screws and clips are placed, as well as how to replace one control panel for a new one. You’ll obviously need to purchase a matching replacement for your microwave model.

Please keep in mind that you should unplug your microwave before fixing it.

Method 5: Call a Professional

A skilled appliance repair professional will be able to replace your microwave’s control panel with ease. They’ll also have a slew of extra troubleshooting methods at their disposal to assist you to locate the source of your microwave’s issue.

Calling for appliance repairs is frequently the most effective method to cure a broken home appliance.

Method 6: Buy a New Microwave

Your final alternative, which many people choose, is to just buy a new microwave. Some appliances were not designed with repairs or part replacements in mind. Most microwaves today are reasonably priced, with the majority of parts and assembly included in the price.

It’s easy to assume that a microwave is fairly cheap to replace, however many times the labor and individual replacement pieces add up more than purchasing a new one of the same make and model, or even something newer and nicer.


If your microwave’s display isn’t working, there are several methods you can try to fix the problem. The first two methods involve checking if something is wrong with the temperature or the fuse.

If those don’t work, you can try replacing the control panel or calling a professional. If all else fails, you might have to buy a new microwave.
