Mystery Solved: Why Your Frigidaire Microwave Keeps Flipping Fuses

If your Frigidaire microwave keeps blowing fuses, it can be a frustrating and potentially dangerous problem. There are several possible causes for this issue, ranging from simple fixes to more serious electrical problems. In this blog post, we will explore the most common reasons why your Frigidaire microwave may be blowing fuses and provide step-by-step instructions on how to troubleshoot and resolve the issue.

Electrical Overload

One of the most common reasons why a Frigidaire microwave blows fuses is an electrical overload. This can occur when too many appliances or devices are plugged into the same circuit, drawing more current than the circuit can handle. To resolve this issue, unplug any unnecessary appliances or devices from the circuit and try using the microwave again. If the fuse no longer blows, you have successfully identified the source of the problem.

Faulty Microwave Door Switch

The microwave door switch is a safety feature that prevents the microwave from operating when the door is open. If the door switch is faulty, it can cause the microwave to draw excessive current and blow the fuse. To test the door switch, open the microwave door and use a multimeter to check for continuity between the two terminals of the switch. If there is no continuity, the switch is faulty and needs to be replaced.

Defective Magnetron

The magnetron is the heart of a microwave oven, generating the electromagnetic waves that heat the food. If the magnetron becomes defective, it can draw excessive current and blow the fuse. To test the magnetron, remove the microwave’s outer casing and use a multimeter to check for continuity between the magnetron’s terminals. If there is no continuity, the magnetron is defective and needs to be replaced.

Arcing Inside the Microwave

Arcing inside the microwave can also cause the fuse to blow. This can be caused by a variety of factors, such as food particles or grease buildup on the interior surfaces of the microwave. To resolve this issue, clean the microwave thoroughly with a damp cloth and remove any food particles or grease. If the arcing persists, there may be a more serious electrical problem that requires professional repair.

Faulty Wiring or Circuit Breaker

In some cases, a blown fuse in a Frigidaire microwave may be caused by faulty wiring or a tripped circuit breaker. To check the wiring, remove the microwave’s outer casing and inspect the wires for any signs of damage or loose connections. If you find any damaged wires, they should be repaired or replaced by a qualified electrician. If the circuit breaker has tripped, simply reset it and try using the microwave again.

Overheating

If your Frigidaire microwave is overheating, it can cause the fuse to blow. Overheating can be caused by a variety of factors, such as a blocked ventilation system or a faulty fan. To resolve this issue, clean the ventilation system and ensure that the fan is working properly. If the microwave continues to overheat, it may require professional repair.

Wrap-Up: Troubleshooting Your Frigidaire Microwave

If your Frigidaire microwave keeps blowing fuses, it is important to troubleshoot the issue to identify the underlying cause. By following the steps outlined in this blog post, you can safely and effectively diagnose and resolve the problem. If you are unable to resolve the issue on your own, it is recommended to contact a qualified appliance repair technician for assistance.
