10 Common Microwave oven Problems & Solutions:


1. Burning Smell from the Microwave

If you smell a burning odour from your microwave, then we advise you to act immediately. There are several reasons which could lead to this smell. It could be due to some leftover burnt pieces of food, which have stayed inside the microwave for a while. Using a non-microwave plastic dish can also cause this disturbing smell. The worst reason could be a fault in the wiring.

  • In case of any faulty wirings, call the technician right away. The longer you wait, the more problems you invite.
  • Lastly, there is a reason why we have so many options of microwave-safe dishes available in the market today. Using a non-microwave plastic dish is a big no. It will cause the plastic to melt, produce a burning smell and even damage your appliance in some ways.


2. Microwave Takes Too Long To Warm Food

This is one of the most common microwave problems. Most people have already experienced it at one point. One common reason for that is filling up the microwave with too much food. You may also experience this issue due to the magnetron malfunction. Using unsuitable cookware or placing the food wrong can also block the heat, reducing the microwave’s efficiency.

  • Adding too much food quantity at one go is the biggest mistake we all tend to do. It will only result in lowering the microwave temperature. As a result, the food will take a long time to warm up. If you want to heat a large portion of food, the best option is to divide the quantity. It will get done faster.
  • A magnetron is the main component of a microwave. To put it simply- a magnetron generates microwave energy. In case of a malfunction, the food will not heat up at all. The only way out to fix this problem is to get it replaced.
  • We want to emphasise how important it is to use the right cookware once again. Using inappropriate material will block heat radiations.


3. Microwave Ceiling Heats Up

Not everyone is well versed with this. But it’s not rocket science. A microwave comprises a wave-guide cover, which is plastic on the top. It is designed to protect the appliance from food particles getting accumulated in the inner section. In the case of tiny food particles on the cover, expect it to get re-cooked and generate heat. It will cause the ceiling to get hot.

It would be best if you kept this section completely clean. Scrape off all the tiny molecules and burnt spots, if any. We recommend you do it with a sponge, damp cloth or paper towel. However, if it does not get managed to be clean, do not hold back. Replace the cover immediately.


4. Microwave Stopping Mid-way

This problem with a microwave could occur due to various breakdowns. It can arise due to a complication with the thermostat, door switch, transformer, fan motor, touch panel or capacitor.

If you are looking for smooth functioning, keeping all the above components intact is a must. Though, we don’t recommend you indulge in repairing it yourself. Seeking expert help is the best possible solution, if possible. Some of these parts are covered in the warranty. So, you can save some extra bucks.


5. Noisy Operation

Operating a microwave should be a silent affair. If you hear any unusual sound, your appliance is in for some trouble. Loud and irritating noises could be due to the burning up of the magnetron, turntable motor, fan motor and wearing out of the stirrer motor.

6. Microwave Light Does Not Turn On While Running

7. Microwave Door Not Closing

There is no way you can operate the microwave without closing the door. The light will surely turn on; however, there will be no energy radiation. Hence, the oven will not do what it is supposed to. So, the microwave door must close properly. This problem with the microwave may arise due to a broken spring or a loose latch assembly.

Are you aware of what leads to the microwave turntable not spinning? Uneven distribution of heat. You may have some parts of your food to be hot and some to be cold. Now let us get to what causes this problem- faulty motor, coupler and guide rollers. Dirt accumulation underneath the turntable may also cause it not to spin.

That can certainly block the turntable movement.

If you clear it all and still have the issue, there is yet something that is not visible but may be a huge hindrance. Detach the glass plate and check if it has been damaged from the bottom. If yes, replace it with a new one.
