10 Common Microwave Problems and How to Fix Them

1. Microwave Not Heating:

If your microwave oven not working properly but not heating up your food, it could be due to a few different issues. The most common cause of is a faulty magnetron, which is responsible for producing the microwaves that heat up your food. Other potential causes include a malfunctioning high-voltage diode, capacitor, or transformer. These issues require professional attention in fixing microwave not heating.

2. Malfunctioning Control Panel:

If the buttons on your microwave’s control panel are not responding or are displaying error messages, it may be a problem with the circuit board. Try resetting the circuit breaker or unplugging the microwave briefly before plugging it back in to solve microwave malfunction. If the issue persists, it may be necessary to replace the circuit board. Our experienced technicians at Tokiso can provide expert troubleshooting and microwave repair services for malfunctioning control panels.

3. Microwave Not Starting:

If your microwave is unresponsive and not starting, it could be due to a few issues. First, ensure it is properly plugged in, and the outlet is working. If that doesn’t solve the microwave problem, it could be a microwave door problem on the switch, thermal fuse, or control board. However, having these components properly checked and replaced by a professional technician is important to ensure that it is done correctly and safely.

4. Strange Noises:

If your microwave makes strange noises, it could be due to several issues. One common cause is a worn or damaged turntable motor, which can create a buzzing, grinding, arcing, or squealing sound. Another potential cause is a faulty cooling fan, which can make a buzzing or humming noise. If you notice any strange noises coming from your microwave, it’s best to have it checked out by a qualified technician to fix common microwave problems.

5. Sparks or Flames:

If you see sparks or flames inside your microwave while in operation, it is important to turn off the appliance immediately and unplug it from the power source. This can be caused by a variety of issues, including a malfunctioning high voltage capacitor, a damaged magnetron, or even metal objects accidentally left inside the microwave. This is a serious issue that requires immediate attention.

6. Overheating:

If your microwave is overheating and shutting off, it may be due to a faulty thermostat or a malfunctioning cooling fan. The thermostat regulates the temperature inside the microwave, while the cooling fan helps to keep the appliance from overheating. If either of these components is not functioning properly, it can result in overheating and automatic shut off.

7. Door Issues:

If your microwave door is not closing properly or is difficult to open, it may be due to a problem with the hinges, latch, or door seal. If the seal is damaged, it can allow microwaves to escape from the appliance, which can be dangerous. Additionally, if the door is not closing properly, it can prevent the microwave from functioning correctly. Our experienced technicians can quickly diagnose and repair any issues with your microwave door, ensuring that it is working safely and efficiently.

8. Broken Turntable:

One of the most common problems with microwaves is a broken or malfunctioning turntable. If the turntable in your microwave has stopped rotating, it may need to be replaced. Check for any obstructions that could be preventing it from turning, such as crumbs or other debris. If there is nothing obstructing the turntable and it still isn’t rotating, it may be due to a malfunctioning motor or a broken drive coupler. If you need help replacing the turntable, our team at Tokiso can provide fast and reliable service.

9. Microwave Not Shutting Off:

If your microwave is not shutting off, it could be due to a faulty door switch, control board, or timer. The door switch is responsible for ensuring that the microwave turns off when the door is opened. If the switch is damaged or not working properly, it may prevent the microwave from turning off. The control board and timer are also responsible for regulating the microwave’s operations. If either of these components is faulty, it can result in the microwave not shutting off.

To diagnose and repair this issue, it is recommended to contact a qualified technician. Attempting to repair this issue on your own can be dangerous and may result in further damage to the microwave. A technician will be able to diagnose the problem and replace any necessary components to get your microwave functioning properly again.

10. Microwave Light Not Working:

If the light inside your microwave is not working, it could be due to a burned-out bulb or a faulty light socket. The light bulb in your microwave can burn out over time, just like any other light bulb. If this is the case, replacing the bulb should fix the problem. However, if the bulb is not the issue, it could be a faulty light socket. The light socket connects the bulb to the microwave and provides power. If the socket is damaged or not working properly, it can prevent the light from turning on.

To fix this issue, start by unplugging the microwave and removing the cover to access the light bulb and socket. If the bulb is burned out, simply replace it with a new bulb of the same wattage. If the bulb is not the issue, you may need to replace the light socket. It is important to ensure that the replacement socket is compatible with your specific microwave model. If you are unsure or uncomfortable with performing these repairs yourself, it is recommended to contact a qualified technician to diagnose and repair the issue.
