Frigidaire microwave no power

Frigidaire microwave no power. Many households have a Frigidaire microwave oven and use it on an almost daily basis. In kitchens across the country, microwaves are used for everything from warming dinners to reheating leftovers.

Because they are such a useful appliance when they stop working it is hard to tell whether the problem is something that can be repaired or if a new microwave is needed.

The first thing that you’re going to want to do if your microwave quits working is consult this list of common problems.

In this article, we will discuss some problems and how to solve them.

Replace the main control board

The main control board may be the problem, but it is rare for this to be the case – most times the location of the trouble can be traced to another area. Main control boards are often misdiagnosed and rarely is a new main control board needed as many appliance companies recommend.

Replace the main control board if all other components are functioning properly. (Caution: As with any appliance with an electrical system, always unplug an appliance and disconnect it from its power source prior to cleaning.)

Fuse issue

If the amperage passing through the microwave circuitry is overloading what the fuse is designed to handle, it may blow. If this turns out to be the case for your situation, chances are that a new fuse will not solve the issue.

What you will want to do next is to determine why exactly it blew in the first place so that you can remain assured that there aren’t any additional fuses on site that might go off due to similar reasons as to why this one did.

 Faulty Thermoprotector

If your microwave isn’t heating things up properly, you might want to see if the problem comes from the temperature protector. Use a multimeter to test the continuity of that Thermo protector.

You’ll know if it’s at fault if its continuity gauge doesn’t go up to five when tested alone. If it can’t be fixed and it can’t be reset, then you’ll have to replace it.

Defective Thermal Fuse

If a microwave overheats, it will shut down. A thermal fuse cuts power to the microwave if it detects unsafe temperatures. Multimeters can be used to test the continuity of the thermal fuse.

Replacement is necessary if there is no continuity. You can’t reset thermal fuses; if they are blown, you need to replace them. Make sure to unplug the microwave before performing any electrical work on it.

FAQs

When a microwave fails to work, what causes it to do so?

One common causes of a microwave oven not working properly are a blown fuse. In a functioning home microwave, there is a timed circuit breaker on the power source which should prevent the microwave from blowing a fuse if it wasn’t installed correctly by an expert or repaired improperly.

The timer fuse should be replaced with the appropriate fuse for your microwave’s electrical rating. Loose connections. If any wires are loose or dislodged in your home’s wiring, they may cause a loss of power to your microwave unit.
