What to do if microwave keeps tripping breaker?

If your microwave is plugged into a GFCI breaker outlet and it keeps tripping, the outlet itself may be at fault. Try resetting the GFCI outlet.

Why does my Frigidaire microwave keep kicking the breaker?

Very likely a door switching sticking. There should be three of them - primary, secondary and monitor. By design, the fuse should blow if a switch sticks. However, with it being a 20a fuse and the circuit breaker possibly being either a 15a or 20a one, the breaker might be tripping before the fuse blows.

Can you use a surge protector with a microwave?

Microwaves should not be plugged into a power strip because it is a safety hazard, can cause a fire, and even damage your electrical system. Most power strips are not rated to handle the 12 to 15 amps that a microwave typically draws.

What happens when a fuse blows in a microwave?

Some microwave fuses called 'thermal fuses' are triggered by heat. So, if the microwave overheats, the fuse will blow and shut the power off to the microwave. Other fuses are triggered by excessive electricity flow through the circuit. A short circuit, for instance, will cause that fuse to blow.

What kind of surge protector do I need for microwave?

Getting the Right Protection
