Microwave Keeps Blowing Fuse: There are a few reasons why a microwave might keep blowing a fuse. Here are some of the most common causes of Microwave Keeps Blowing Fuse:
- Defective door switch: The door switch is responsible for detecting when the door is closed and preventing the microwave from operating when it is open. If the door switch is defective, it may not detect that the door is closed, which can cause the fuse to blow.
- Defective magnetron: The magnetron is the part of the microwave that produces the microwaves. If the magnetron is defective, it can cause a surge in electricity, which can blow the fuse.
- Defective high-voltage capacitor: The high-voltage capacitor stores the electricity that powers the magnetron. If the capacitor is defective, it can cause a surge in electricity, which can blow the fuse.
- Loose or damaged wiring: Loose or damaged wiring can cause a short circuit, which can blow the fuse.
- Overload: If you try to use your microwave with too many appliances plugged into the same outlet, it can overload the circuit and blow the fuse.
If your microwave keeps blowing a fuse, it is important to have it repaired by a qualified technician. Attempting to repair the microwave yourself can be dangerous, as it involves working with high-voltage electricity.

Here are some tips to help prevent your microwave from blowing a fuse:
- Make sure that the door switch is working properly. You can test the door switch by closing the door and then opening it again. If the light on the door switch turns off when you open the door, then the switch is working properly.
- Avoid using metal objects in the microwave. Metal objects can reflect microwaves, which can cause a fire or damage the microwave.
- Do not overload the circuit. Only plug one appliance into each outlet.
- Have your microwave serviced regularly by a qualified technician. This will help to identify and repair any potential problems before they cause a fuse to blow.
What would cause a fuse to keep blowing?
There are a few reasons why a fuse might keep blowing. Here are some of the most common causes:
- Overload: If too much current is flowing through the fuse, it will blow. This can happen if you plug too many appliances into a single outlet or if an appliance is defective and draws more current than it’s supposed to.
- Short circuit: A short circuit occurs when there is a direct path for current to flow from one wire to another. This can happen if the insulation on a wire is damaged or if two wires touch each other. A short circuit can cause a fuse to blow because it allows a large amount of current to flow through the fuse.
- Ground fault: A ground fault occurs when current flows from an appliance to the ground. This can happen if the insulation on a wire is damaged or if a metal object comes into contact with an energized wire. A ground fault can cause a fuse to blow because it allows current to flow through the fuse that is not intended to flow through it.
- Defective fuse: A fuse can also blow if it is defective. This can happen if the fuse is old or if it has been damaged in some way.
If a fuse keeps blowing, it is important to find the cause of the problem and fix it. If you cannot find the cause of the problem, you should have an electrician inspect the electrical wiring in your home.
Here are some tips to help prevent fuses from blowing:
- Do not overload circuits. Only plug one appliance into each outlet.
- Check for loose or damaged wiring. Loose or damaged wiring can cause a short circuit, which can blow a fuse.
- Use the correct size fuse. Make sure that the fuse you are using is the correct size for the appliance you are using.
- Replace fuses regularly. Fuses have a lifespan, and they should be replaced every few years.
- Have your electrical wiring inspected regularly by an electrician. This will help to identify and fix any potential problems before they cause a fuse to blow.
Will the microwave work if the fuse is blown?
No, a microwave will not work if the fuse is blown. A fuse is a safety device that prevents electrical currents from becoming too high. If the fuse blows, it means that there is a problem with the microwave’s electrical system and it is not safe to use.
The following are some of the reasons why a microwave fuse might blow:
- Short circuit: A short circuit occurs when there is a direct path for electricity to flow from one wire to another. This can happen if the insulation on the wires is damaged or if there is a loose connection.
- Overheating: The microwave’s electrical components can overheat if they are not properly ventilated. This can happen if the microwave is blocked or if the vents are clogged.
- Defective parts: If any of the microwave’s electrical components are defective, it can cause a fuse to blow.
If you find that your microwave’s fuse has blown, you should not attempt to repair it yourself. Instead, you should contact a qualified appliance repair technician.
Here are some tips to help prevent your microwave fuse from blowing:
- Keep the microwave clean: Wipe down the inside and outside of the microwave with a damp cloth after each use. This will help to prevent food particles from building up and causing a fire.
- Avoid overloading the microwave: Do not put more food in the microwave than it can handle. Overloading the microwave can cause the magnetron to overheat and blow the fuse.
- Do not use metal utensils in the microwave: Metal utensils can cause sparks and start a fire.
- Do not use the microwave if it is damaged: If the microwave is damaged, it is not safe to use. Contact a qualified appliance repair technician to have the microwave repaired or replaced.
