Why Does Microwave keep Blowing Fuse?
There are a number of issues that can cause a microwave to blow its fuse. These include things like a faulty door switch. If the microwave is equipped with a turntable, it may have a short circuit or a mechanical problem.
The magnetron may also be malfunctioning and drawing too much power. The fuse is there to protect the microwave from overheating. If it blows, the device will need to be repaired by a technician.
If the fuse blows when you try to turn on the microwave, the problem may be as simple as the wrong power settings.
Microwaves use a lot of power, and if yours is connected to the same circuit as a heavy-draw appliance like an electric stove, the fuse could be tripped as a safety precaution.
You might also try flipping the microwave over and making sure it’s plugged in.
Microwave Won’t Turn On
Microwaves don’t just turn on all by themselves. There is a specific process that you must follow in order to get them to work. First, make sure the device is plugged in and that the outlet has power.
Then, press the power button. If the microwave doesn’t turn on after pressing the button, the fuse may have blown. In order to fix the issue, you’ll need to call a technician and have the fuse replaced.
Alternatively, you may have simply misused the microwave. If you’ve tried pressing the power button and the microwave still doesn’t turn on, make sure that the device is plugged in and the fuse isn’t blown.
If those things check out, try pressing the start button. Some microwaves have a “quick start” button that works as a power button. If the microwave still doesn’t turn on, you’ll need to call a technician.
Microwave Door Will Not Close
A microwave that won’t close all the way may be misaligned. If the door is misaligned, it may not close completely and may not be sealed properly. To fix this issue, first, ensure that the microwave is unplugged. Then, open the door and look at the hinges.
If they look misaligned, use a screwdriver to adjust them. You can also use a coin in place of a screwdriver if you don’t have one available. Once you’ve aligned the hinges, close the door and try turning on the microwave again.
Microwaves also have an auto-rotate feature that may cause the door to not close properly. If the door won’t close, open the device and check for a switch that says “auto-rotate.”
If there is no switch, but the microwave door is not closing, it may need to be replaced. Note that this is a very rare occurrence.
The Display Is Out Or Showing Strange Characters
If the display is out on your microwave, it can cause a number of issues. First, make sure that there isn’t a fuse that has blown. If the fuse is intact, the display may be faulty and will need to be replaced.
If the fuse has blown, you may simply need to replace it. If the fuse is intact and the display is out, the microwave may have a larger issue.
It may need to be repaired. If the microwave is relatively new and has been properly maintained, the problem may be due to a software glitch.
In that case, the microwave may need to be reprogrammed or have its software updated.
The door may be misaligned or damaged
Sometimes the microwave door is just not closing properly, and no matter how much you fiddle with it, you can’t seem to get it to line up right.
The first thing you’d want to do in this situation is check the hinge screws, and see if they are tight. If they are, and the door is still not closing properly, you could have a bent door, or the hinges may be snapped.
In this case, you will have to replace the hinges. The hinges are usually made from metal, but some are made from plastic, so it is important that you check the type of hinges that are on your microwave before you buy new ones.
Why does my microwave keep blowing fuses?
Microwaves are notorious for blowing fuses. The most common reason a microwave blows a fuse is because the thermostat is set too high.
Microwaves work by alternating AC power from the wall outlet with microwaves to cook food. If the thermostat is set too high, it will constantly turn on and off, which means that you’re going to have an electrical problem.
There’s also a possibility that you have an appliance plugged into your power strip or something else in your house has overloaded the circuit.
In this case, try to move the oven elsewhere so it won’t be on the same circuit as something else that’s causing it to blow fuses.
If none of these things work and your microwave still keeps blowing fuses, you may need to replace the power cord or transformer.

What should you check first?
It is important to determine what the problem with your microwave is so you can fix it.
If your microwave keeps blowing fuses, it’s usually because of the power cord or transformer.
First, check to see if the fuse on your circuit board needs replacing and if that doesn’t work, replace the power cord or transformer.
Is it the fuse or power cord?
One of the most common reasons a microwave might blow a circuit fuse is due to a power cord issue.
A power cord can get overloaded and overheat because the microwave is getting too much power. To fix this problem, you’ll need to replace the power cord.
If replacing the power cord doesn’t solve the issue, then your problem could be that your transformer is not working properly.
To find out if this is the case, you should first check for blown fuses inside of your microwave. If all of the fuses are good and not blown, then it’s likely that your transformer needs to be replaced.

Replacing Power Cord and Transformer
You may need to replace the power cord if you have a microwave that keeps blowing fuses.
Microwaves are equipped with thermal cut-off switches that will automatically turn off the appliance when it overheats and detects that a fuse has blown.
This is done to prevent fires. Some power cords can be easily swapped out, while others may need to be replaced.
A transformer will also cause your fuse to blow. Transformers change voltage levels of electricity so your microwave can function properly.
You’ll want to replace the transformer if you notice any arcing or sparking in the area where the electrical contacts are located or around the pins on the transformer.
A burnt odor is also a sign of a problem with your transformer.
FAQS
Is it safe to use a microwave if the power cord is damaged?
No, do not use your microwave if the power cord or transformer is damaged. Doing so could cause electrocution or an electric shock!
What do you do if your microwave starts smelling like burning?
If the microwave is overheating and causing the food inside it to burn, there may be a risk of setting the house on fire. In this case, it is best to unplug the microwave and call a technician to come out and inspect the device.
