How to Replace Fuses in Whirlpool Microwaves

A bad fuse is one of the most common problems on microwaves, including Whirlpool ovens. Most modern microwaves use the same style of fuse which you can find at most appliance and electronics stores. The difficulty of replacing the fuse in a Whirlpool microwave can vary depending on whether you are working on a countertop microwave or a built-in. Knowing where to start can make the process much easier for either style of microwave.

Countertop Microwaves

Step 1

Unplug the microwave and let it sit for a few minutes before beginning repairs. Bring it to a clear area with enough room to work. Leave enough room to have access to it on all sides.

Step 2

Remove the Phillips screws from the outer shell of the microwave. The screws are located along the lower sides and around the edges of the back. Put the screws into a bucket or bowl to keep them together. Pull the shell away from the microwave, and set it to the side.

Step 3

Look for the fuse inside the exposed controls of the microwave. The fuse is located in a small receptacle with two wires running to it. Use a flat screwdriver to pry up from the bottom of the fuse. The fuse will pop out. Replace the fuse with a new one.

Built-in Microwaves

Step 1

Unplug the microwave, and let it sit for a few minutes before beginning repairs.

Step 2

Open the microwave door, and look for two Phillips screws along the left side of the control panel. Remove these screws. Lift up on the control panel, and tilt it outward. The control panel will rest on its hinges.

Step 3

Find the fuse receptacle within the control area. Is is usually located to the left or center of the cavity. You will see two wires that go to either end of a small, plastic receptacle. Use a flat screwdriver to pry up on the bottom of the fuse. The fuse will pop out. Replace the fuse with a new one.
