The Shocking Truth: Why Is My Microwave Constantly Shorting Out?
What To Know
- This can be a problem with the microwave itself, or it can be a problem with the electrical outlet that the microwave is plugged into.
- If you suspect that your microwave has been damaged by a power surge, it’s best to call a qualified electrician to take a look.
- The most common causes are overheating, faulty wiring, a dirty magnetron, a faulty door switch, a blown fuse, a power surge, or a manufacturing defect.
Every household needs a microwave, but it can be frustrating when it suddenly starts shorting out. This can be a safety hazard, and it can also be a major inconvenience. If you’re wondering why your microwave keeps shorting out, there are a few possible causes.
1. Overheating
One of the most common causes of microwave shorts is overheating. This can happen if the microwave is used for too long at a high power setting. It can also happen if the microwave is not properly ventilated. Make sure that the microwave has plenty of space around it so that air can circulate freely.
2. Faulty Wiring
Another possible cause of microwave shorts is faulty wiring. This can be a problem with the microwave itself, or it can be a problem with the electrical outlet that the microwave is plugged into. If you suspect that the wiring is faulty, it’s best to call a qualified electrician to take a look.
3. Dirty Magnetron
The magnetron is a key component of a microwave oven. It generates the microwaves that heat the food. If the magnetron is dirty, it can cause the microwave to short out. To clean the magnetron, simply remove the cover and wipe it down with a damp cloth.
4. Faulty Door Switch
The 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 short out. To test the door switch, simply open and close the door several times. If the microwave does not turn on, the door switch may be faulty.
5. Blown Fuse
A blown fuse can also cause a microwave to short out. The fuse is a safety device that protects the microwave from electrical surges. If the fuse blows, it will need to be replaced. To replace the fuse, simply locate the fuse box and replace the blown fuse with a new one of the same amperage.
6. Power Surge
A power surge can also cause a microwave to short out. Power surges can be caused by lightning strikes, downed power lines, or other electrical problems. If you suspect that your microwave has been damaged by a power surge, it’s best to call a qualified electrician to take a look.
7. Manufacturing Defect
In some cases, a microwave may short out due to a manufacturing defect. If you suspect that your microwave has a manufacturing defect, you should contact the manufacturer. The manufacturer may be able to repair or replace the microwave under warranty.
Wrapping Up
If your microwave keeps shorting out, there are a few possible causes. The most common causes are overheating, faulty wiring, a dirty magnetron, a faulty door switch, a blown fuse, a power surge, or a manufacturing defect. If you’re not sure what the cause is, it’s best to call a qualified electrician to take a look.
Answers to Your Most Common Questions
Q: Why does my microwave keep tripping the breaker?
