Microwave is a very common item in our kitchen. However, after a period of use, many people often encounter the condition that the oven is ringing, causing unpleasant noises.
Why is the microwave making a loud noise?
The loud noise of the microwave oven after a period of use comes from many different reasons, specifically:
- Cooling fan: After using the microwave oven, the inside of the oven is still hot . At this time, the fan in the oven will work to dissipate heat and cool the components. Therefore, if you open the oven door suddenly after cooking, the radiator fan will not be able to stop completely, and this may create a loud noise.
- Do not clean the microwave: After a long time of use, dirt will accumulate inside the microwave oven and cooling fan. If not cleaned periodically , the thick layer of dust will hinder the heat dissipation process and cause the components inside the oven to heat up . This causes the fan to not be able to dissipate heat effectively, thereby causing a loud hum.
- Oil-drying fan: Microwave fan uses lubricating oil to reduce friction and noise . If the fan operates continuously without periodic lubrication , the oil may dry out and produce an unusually loud noise.
- Microwave overload: If the microwave oven has to operate continuously for a long time, the components inside the oven may not have enough time to cool down . This may cause the oven to make an unpleasant noise.
- Covered heat outlet : Microwave ovens often have heat vents to help reduce the internal temperature. If you let items cover the air outlet, heat cannot escape, and the oven will make a loud noise.
- Damaged cooling fan : After a long time of use, the blower in the microwave oven may be damaged or malfunction , causing inefficient heat dissipation and making abnormal noises.
- The dish wheel does not match the spindle: In some cases, the dish wheel inside the microwave may not match the spindle perfectly , causing a loud and uneven noise when the oven is operating.
How to fix a noisy microwave
To fix the problem of the microwave making a loud noise, you can do the following methods:
- Give the oven time off: When using a microwave oven, give it a break between cooks so that the components inside the oven cool down and don't overheat. This helps to avoid overloads and reduce noise.
- Clean the microwave periodically: Clean the microwave regularly to remove dirt inside and outside the oven. If the thick layer of dust is not removed, it can interfere with heat dissipation and increase the noise of the oven.
- Lubricate the radiator fan: Check the oven radiator fan and lubricate if necessary. This helps the fan operate quietly and reduces unwanted noise.
- Place the oven in a suitable position: When using, you should place the oven in a flat, cool place and avoid letting items cover the heat outlet in the oven. This helps to ensure that the hot air in the oven can escape efficiently.
- Check the turntable wheel and spindle: If strange noises are detected from the inside of the oven, check the joints of the turntable wheel and the crankshaft . If you see a deviation, disconnect the power and re-adjust them to match.
- Call for service: If the above steps do not resolve the problem, turn off the oven, unplug the power cord and take the oven to a service shop or contact the manufacturer's technical service for service. Timely repairs.
Instructions for safe use of the microwave
Before using the microwave oven
- Microwave Test: Before using, check the microwave oven to make sure it is working properly and that the oven door is closed tightly.
- Read the instructions for use: Read the instruction manual that came with the microwave oven carefully to understand the functions and how to use the oven.
- Ensure safe operation: Flammable or metallic materials should not be placed near the microwave oven, as they may cause a fire or an explosion hazard.
During the use of the microwave
- Use the right cups and plates: Use microwave-specific heat-resistant utensils .
- Correct time setting: Make sure to set the correct cooking time to avoid overcooking, causing an explosion.
- Keep a distance: Always keep a safe distance when opening the oven door, do not put your hands and face too close to the control button to avoid burns.
After using the microwave
- Take care when removing food: When removing food from the microwave, use a clean towel or heat gloves to avoid burns.
- Check the status of the oven: Check the oven after use to make sure it is completely powered off.
- Clean the Oven Regularly: Clean the microwave oven periodically to remove dirt that has accumulated inside and outside the oven.
- Do not leave the oven running on empty: Avoid leaving the oven on empty as this may cause a fire.
How to put food in the microwave
The way food is placed in the microwave is also important to ensure that the food cooks evenly and is safe to use. Here are some tips when placing food in the microwave:
- Place the food evenly on the turntable: When using the turntable, place the food evenly . This helps the food to cook evenly , because as the turntable rotates, the temperature in the oven is evenly distributed through the food.
- Stirring food mid-cooking: When using the microwave for cooking, especially with large foods, turn the food around at about half of the cooking time . This helps ensure that the food cooks evenly on both sides and avoids burning or uneven cooking.
