Amana Microwave Keeps Blowing the Fuse [Solution]

If your Amana microwave keeps blowing the fuse, no matter how many times you replace the fuse, it won’t fix the problem unless you get to the root. So, before replacing the fuse, you first need to find the source of the problem. In this article, we are going to talk about why your Amana microwave keeps blowing the fuse and what to do about it.

Why Does My Microwave Keep Blowing the Fuse?

If your Amana microwave keeps blowing the fuse, the most common reason for this is the high voltage capacitor. If this component is faulty, your microwave fuse will keep blowing even if you replace it. Before you replace the capacitor in a microwave, please note that it houses a dangerous amount of electricity which could cause fatal injury or death if not discharged.

So, to avoid the risk of injury, make sure to follow every single step listed. To replace the capacitor in an Amana microwave, do the following…

Step 1: Turn off the microwave and unplug it.

Step 2: Have someone else support the bottom of the microwave as you take out the bolts which secure it to the cabinet.

Step 3: Tilt the microwave forward and pass the power cord through the hole.

Step 4: Lift the microwave from the mounting plate and place it on a towel lined sturdy surface.

Step 5: Take out the screws securing the front grille. Depending on your microwave model, there will  be 2-4 screws.

Step 6: Remove the grille.

Step 7: Open the microwave door and take out the glass tray and support if still inside.

Step 17: To avoid getting seriously injured, you will need to discharge the capacitor. Do this by placing a pair of pliers with insulated handles over the two terminals on the capacitor. When you hear a pop, the discharge is successful.

Step 18: Take out the screws which secure the inner access panel.

Step 19: Remove the access panel.
