1. Signs Your Microwave Isn't Heating
Microwaves are a familiar and widely used kitchen appliance today. Besides reheating food, microwaves also help reduce the effort in cooking and preparing many dishes.
If one day you find your microwave taking a long time to heat food or not heating at all, even though you've adjusted the time and power levels as usual, then your microwave may be experiencing a heating issue.
2. Causes and Solutions for Microwave Not Heating
Microwave is not receiving power and therefore not functioning
Common Reasons and Effective Fixes for a Microwave Not Heating Up
If your microwave isn't heating up or functioning, it could be because you forgot to plug it in. Or it could be due to a loose plug or a faulty socket that prevents electricity from reaching the microwave.
- Check the power plug to see if it's loose. If so, plug it back in and turn on the microwave to see if it works normally.
- Thoroughly check the microwave's power cord for any cuts or breaks. If you find the cord damaged, replace it with a new one or have a repair technician fix it.
- Inspect the power socket. If the microwave works when plugged into a different socket, the original socket may be faulty. Check and repair the socket accordingly.
Microwave Waveguide Cover Damaged
Frequent operation at high temperatures can cause the microwave to get dirty with food debris and grease buildup around the microwave. Without regular cleaning, the waveguide cover inside the microwave is prone to dirt accumulation. This affects the heat supply and operation of the microwave.
To fix this issue, clean the waveguide cover regularly with a mild soap solution or vinegar. Avoid using abrasive cleaners that could damage the cover. Additionally, ensure that the microwave is properly ventilated and not overloaded with food.
- Regularly clean the microwave after use, wait for it to cool down before cleaning.
Microwave not heating due to improper container use.
One of the reasons the microwave is not heating may be due to the use of inappropriate food containers. Some materials such as stainless steel, metal, or plastic should not be used in the microwave. Because they will affect heat transfer or microwave reflection.
To fix this issue, you should replace them with materials: heat-resistant glass, porcelain, or plastic materials suitable for microwaves.
2.4. The device is too old
If your microwave has been used for many years, it may also be the cause of the microwave not heating or heating slowly.
If your microwave oven has been used for a long time but does not heat up, you should consider buying a new one.
2.5. Microwave oven fuse blown
The fuse is one of the parts that protect the microwave oven in case of short circuits or electrical fires. Prolonged use of the microwave oven at high temperatures can cause the fuse to blow.
Troubleshooting:
- Remove the power cord of the oven and remove the back cover. Find and remove the fuse box.
Open the fuse box, then use a pen tester to check if the two ends of the fuse are lit.
Besides the fuse, the circuit board is also an important part of the microwave. If the circuit board is damaged, the microwave will not work or will operate but cannot heat up.
This is a serious problem that requires skilled and experienced repairmen. Therefore, if you determine that the microwave is faulty due to a damaged circuit board, you should take it to repair centers or warranty centers for inspection and troubleshooting.
2.7. How does a microwave oven break down the processing capacitor?
The high-voltage capacitor is a component that charges and discharges electricity, helping to increase the power supply to the high-frequency tube (or waveguide block). When the high-voltage capacitor is damaged, it will cause the microwave to not heat up.
Troubleshooting: Check the capacitor with a VOM meter. If the capacitor is damaged, you should take the microwave to a repairman to replace this component.
Above are the causes and solutions for the microwave not heating up. Hopefully, through this article, you will find the cause of the problem with your microwave.
