Sometimes, replacing the power outlet can help fix several common issues that occur in Frigidaire microwaves.

Power Fluctuation

In case of a power outage, it’s also recommended to check for any tripped breakers. Frigidaire microwave fuse is designed to blow up when extra current flows through it.

In this situation, you should replace the fuse and see if it works. You should also reset the breaker before replacing the fuse. However, if your breaker keeps tripping and the fuse keeps blowing, you should take your microwave to a professional technician.

Wrongly Installed Fuse/Wrong Fuse Type

While installing the fuse, you should make sure that the connectors are facing the right direction. If you don’t install the fuse correctly, it will keep blowing. Additionally, you should also check if you have installed the right fuse in your microwave.

For this purpose, you can read the Frigidaire microwave manual and install the fuse correctly. You should also check which fuse type is compatible with your microwave and install that one.

Frigidaire Microwave Door Lock

The Frigidaire microwave fuse keeps blowing the door interlock might be malfunctioning. In this case, you have to test the switch in the following manner:

  • Unplug your Frigidaire microwave and remove its cover.
  • Look for the door interlock under the area where the door hooks fasten to the frame. 
  • Now, check the continuity with the help of a multimeter.
  • When you press the button, you should have continuity, but when you release it, there should be no continuity.

If there is no continuity even after pressing the button, you have to replace the door switch.

You should keep in mind that microwaves can store a lethal amount of electricity and such repairs should not be attempted on your own. It is recommended to either contact the service center of Frigidaire or a professional technician for such repairs.

Overloaded Circuit

Circuit overload is another reason that can cause problems in your Frigidaire microwave. It normally happens when you use a shared circuit and other appliances can cause an overload in the circuit and blow up your microwave fuse.

 You can fix it by using a separate circuit for your Frigidaire microwave. If you want to fix your existing circuit, call an electrician.

Loose Metal Objects

If there are any loose metal objects in your Frigidaire microwave, they can cause a short circuit and the fuse will blow up. However, to check these objects, you have to disassemble the microwave.

In order to fix this, you should check if there are any loose screws and replace/tighten them.

Frigidaire Microwave Faulty Magnetron

If the magnetron of your Frigidaire microwave is burned or faulty, it can cause plenty of problems like a blown fuse or the microwave not turning on. Magnetron is responsible for heating your food so a microwave cannot work with a faulty magnetron.

It is not possible to check your microwave’s magnetron without removing its cover, so it is recommended that you contact the Frigidaire repair center or call a qualified technician to check and replace the magnetron.

How to Check and Replace Frigidaire Microwave Fuse?

  • Turn off the Frigidaire microwave and unplug it from the power outlet.
  • Remove the microwave cover and unscrew the fuse.
  • Check the Fuse continuity with the help of a multimeter.
  • If there is no continuity, replace the fuse with a new one.
  • Now, assemble your microwave again and plug it into a wall socket.
  • Turn your microwave on and check if it works. You can use a glass of water and warm it for 30 seconds.
