Why Is My Microwave Getting Hot on the Outside? Possible Causes and Solutions

I love food, and I especially love the convenience of microwave cooking. It’s quick, easy, and saves so much time in the kitchen. However, I recently noticed that my microwave was getting hot on the outside, and it got me worried. I decided to dig deeper and figure out what could be causing this issue.

1. Overheating due to prolonged use

One possible cause of your microwave getting hot on the outside is that it’s simply overheating. If you’ve been using your microwave for an extended period, it’s natural for it to get warm. However, if it’s getting hot to the touch, it could be a sign of a more significant problem.

  • Make sure you’re following the manufacturer’s instructions regarding the recommended cooking durations. Prolonged use beyond the recommended time can cause overheating.

  • Allow your microwave to cool down between cooking sessions. This will give it a chance to dissipate any excess heat and prevent overheating.

  • Check the vents on your microwave. Blocked vents can obstruct the airflow, causing the microwave to overheat. Ensure they are free from obstructions such as dust, debris, or kitchen utensils.

    • 2. Malfunctioning magnetron or diode

    The magnetron is the component responsible for producing the microwaves that heat your food. If it is malfunctioning, it can cause the microwave to overheat and become hot on the outside. The diode, which controls the flow of electricity, can also cause similar issues if it is faulty.

  • Contact a professional technician if you suspect a problem with your magnetron or diode. They will be able to diagnose the issue and provide appropriate solutions.

    • 3. Damaged waveguide

    Another possible cause of your microwave getting hot on the outside is a damaged or deteriorating waveguide. The waveguide is a metal tube that directs the microwaves from the magnetron to the cooking chamber. If it is damaged, the microwaves can escape and heat the exterior of your microwave.

  • Examine the waveguide for any signs of damage, such as cracks, burns, or moisture. If you notice any issues, it is best to contact a professional for repair or replacement.

    • 4. Faulty door seals or latches

    Properly functioning door seals and latches are essential for your microwave’s safety and efficiency. If they are faulty, heat can escape and cause the exterior of the microwave to become hot.

  • Inspect the door seals and latches for any signs of damage or malfunctions. If you notice any issues, contact a professional technician to replace them.

    • 5. Cooking with incorrect containers

    Using the wrong type of containers while microwaving can also cause your microwave to get hot on the outside.

  • Avoid using metal or aluminum foil containers, as they can cause sparks and damage to the microwave.

  • Use microwave-safe containers made of glass, ceramic, or microwave-safe plastic.

  • Ensure that the containers you use are in good condition and do not have any cracks or chips that could cause them to heat unevenly.

    • Conclusion

    Microwaves are incredibly convenient appliances in our kitchens, but it’s crucial to ensure they are functioning correctly. If you notice that your microwave is getting hot on the outside, don’t ignore it. It could be a sign of a more significant problem that requires attention.

    By following the possible causes and solutions mentioned above, you can troubleshoot and resolve the issue. However, if the problem persists or you’re unsure about the exact cause, it is always advisable to contact a professional technician. They have the expertise to diagnose and fix the problem, ensuring the safety and efficient functioning of your microwave.
