Why Is My Microwave Wet Inside? (Quick Answers)

Is your microwave wet inside? It may be time for a good cleaning. It may be helpful to wipe down the interior of your microwave with a damp cloth to remove any residue that has built up over time.

What causes the microwave to become wet inside? What can you do to solve the problem? Let’s take a look.

Microwave wet inside:

Most microwave ovens become wet when moisture accumulates on the internal metal surface. Additionally, the high temperatures of the microwave may cause water vapor to form and condense on the metal. Microwaves may be wet inside due to the condensation that forms when food is microwaved.

A wet microwave may also result from an improperly installed door seal or a leak inside the oven. It might be time to give your microwave a good cleaning if it has been getting wetter over time. These are some common reasons and solutions for microwaves being wet inside.

Moisture accumulation:

Wiping down your microwave interior with a damp cloth might help remove any residue that has built up over time. The problem might, however, be caused by moisture accumulation if it persists.

By cleaning out the vent holes and cracks around the oven, heat can be distributed more evenly, and moisture will be prevented from accumulating.

Consider installing a water-resistant sealant around the door or frame to solve moisture accumulation problems.


Foods are microwaved, causing water vapor to condense on the metal surfaces. As a result, your microwave can become wet inside.

Be sure that all surfaces are cool before loading your food into the microwave, and avoid placing too many heavy items in front of the oven vent openings. You may need to replace your damaged unit if condensation persists after taking these precautions.

Poor Ventilation:

Inadequate ventilation can also lead to a wet microwave. When oven fumes are trapped inside, moisture will be drawn into the oven and it will become wet.

If you want to reduce the chances of this happening, open all of the vents and flaps on your microwave. Water-resistant sealants can also be used around these areas to keep moisture out.


It may be due to overheating if your microwave is constantly getting wet. Before loading your food into the oven, ensure that it is properly heated and the power cord is plugged into a grounded outlet.

Clean out any dust or debris accumulated inside the oven cavity and check for dangling cords or wires. It might be necessary to replace your unit if none of these measures solve the issue.

Badly Worn Parts:

Your microwave may be wet all the time, even after taking precautions to prevent moisture accumulation, because some parts are wearing out. A metal will become porous over time, allowing water to seep through.

You might need to replace key components like the heating element or magnetron if this occurs.

Defective Magnetron:

The magnetron of a microwave can also become defective, which can result in a wet microwave. Oftentimes, this part is responsible for generating microwaves and if it fails, then the oven will not work correctly or you will be unable to heat anything in it.

If you notice any strange smells coming from the oven, or if it becomes constantly wet, it may be time to replace the magnetron if you notice any strange smells coming from there.

Getting moisture out of the microwave:

Microwave moisture can cause serious problems. You can reduce the amount of moisture in your microwave by doing a few things.

Ensure adequate airflow:

By opening all of the vents and flaps in the oven, you can ensure that there is sufficient airflow through the oven. As a further measure to help prevent moisture from getting into these areas, you can also use a water-resistant sealant around them.

Clean the oven:

There can also be moisture buildup inside the oven over time. Regular cleaning will help to remove dust and moisture accumulations, which in turn will reduce the amount of moisture that accumulates.

Avoid overloading the oven:

Moisture can also accumulate in your microwave if it is overloaded. Don’t put too many objects in the oven at once, and ensure that all the parts of the appliance are sealed properly.

Avoid accumulating food debris:

Avoid accumulating food debris inside the microwave, as this will also cause moisture buildup.

You should instead place your food in a dish or container and then place that in the oven. The microwave may need to be replaced if none of these measures resolve the moisture accumulation issue.

Can condensation damage your microwave?

During cold weather, moisture from food can condense on the inside of your microwave. This can cause corrosion of electrical components, so if this happens, you may want to consider replacing your microwave.

Here are some problems that can occur when your microwave condenses.

Corrosion of electrical components:

Your microwave’s electrical components can be corroded if condensation builds up on their surfaces. There may even be a need to repair the power supply of your oven as a result.

Water damage:

Getting water inside the microwave will damage the internals. Mold and other moisture-related issues, as well as electric shorts, could result from this leak.

This can lead to bacteria growth:

Bacteria can also grow due to condensation. Microwaves can develop harmful mold and other microbial problems if water gets trapped inside and not appropriately cleaned.

Water can become hot and can cause burns:

Water can also become hot due to condensation, which can cause burns. Using a microwave covered in condensation is not recommended for those with sensitive skin.

7 tips to properly use your microwave to prevent condensation:

When moisture forms on metal surfaces, condensation occurs, which makes using the microwave oven difficult.

Eventually, the microwave’s performance decreases as a result of the formation of water droplets on its interior. To prevent condensation in your microwave, follow these tips.

Avoid using the microwave if it is cold outside:

Use your microwave sparingly if the weather is cold, as condensation will form on the inside surfaces. Alternatively, you can place a bowl of hot water inside your oven when you want to use it in advance.

Clean your microwaves regularly:

Keeping your microwave clean is important to prevent the buildup of moisture and the corrosion of electrical components within your microwave.

Ensure that all areas that come in contact with the food are thoroughly cleaned, including under the turntables as well as around any openings and vents that come into contact with the food.

Avoid placing heavy objects on the turntable:

Make sure you don’t place heavy objects on top of your microwave when it has a turntable so that it doesn’t damage the turntable. When this happens, the turntable is likely to wobble, and heating is likely to be uneven as a result.

Ventilate your oven well:

You should always open the doors and windows of your oven whenever you’re not using it to ensure that it is well ventilated. By doing this, you will be able to redistribute heat evenly within the oven and prevent condensation from forming inside it.

Keep moisture away:

Before placing food inside the microwave, make sure it is dry and free of moisture. By doing so, condensation will be prevented on the food, and the food will also remain fresh for longer.

Place food in a single layer:

To reduce the chances of your food being overcooked or burned, make sure that you place it in a single layer whenever placing it in the microwave.

Chop food small:

Whenever you chop food, be sure that the pieces are small enough to be able to cook evenly so that you don’t have to worry about cooking them in large pieces.

The food will also be protected from any condensation that may form on the surface of the food by doing this.

When to ask for professional help?

Taking your microwave in for repairs may be a good idea if you still have problems with it. See if there is anything that can be done to resolve the issue by contacting a professional technician.

Listed below are some common situations when you should call a professional. When your microwave stops working. An unpleasant smell is coming from your microwave.

If the food is cooked unevenly. Electrical components that are starting to corrode. The oven is becoming too hot. The door isn’t closing properly.

Final Thoughts

To conclude, moisture accumulation, condensation, poor ventilation, bad parts, and overheating can cause a wet microwave. Ensure that your oven is clean and free of debris to reduce the possibility of moisture accumulation. Cooking in a wet environment will result in condensation.
