Why is my microwave getting hot on the outside? Discover the surprising reason behind this common issue

Ever wondered why your microwave gets hot on the outside? It’s a common issue that can be caused by a variety of factors. In this blog post, we’ll explore the most common reasons why your microwave is getting hot on the outside and provide solutions to help you fix the problem.

Causes of a Hot Microwave Exterior

1. Overheating: When a microwave is used for extended periods or at high power levels, it can overheat, causing the exterior to become hot.
2. Ventilation Issues: Microwaves require proper ventilation to dissipate heat. If the ventilation holes are blocked or obstructed, heat can build up and cause the exterior to overheat.
3. Faulty Door Seal: A damaged or worn door seal can allow heat to escape, causing the microwave to overheat and the exterior to become hot.
4. Malfunctioning Magnetron: The magnetron is the component that generates microwaves. If the magnetron malfunctions, it can cause the microwave to overheat and the exterior to become hot.
5. Overcrowding: Placing too many items in the microwave can block ventilation and cause it to overheat.
6. Defective Thermal Fuse: The thermal fuse is a safety device that prevents the microwave from overheating. If the thermal fuse is defective, it may not trip when the microwave overheats, leading to the exterior becoming hot.
7. Power Surges: Power surges can damage microwave components, including the magnetron and thermal fuse, causing the microwave to overheat and the exterior to become hot.

Solutions

1. Allow Cooling Time: After using the microwave, allow it to cool down for a few minutes before using it again.
2. Ensure Proper Ventilation: Make sure the microwave is placed in a well-ventilated area with at least 2 inches of clearance on all sides.
3. Check the Door Seal: Inspect the door seal for any damage or wear. If the seal is damaged, replace it immediately.
4. Contact a Qualified Technician: If the microwave is still getting hot on the outside after trying the above solutions, it’s best to contact a qualified technician to diagnose and repair the problem.
5. Use the Microwave Wisely: Avoid using the microwave for extended periods or at high power levels. Only heat small amounts of food at a time.
6. Avoid Overcrowding: Place only a few items in the microwave at a time to ensure proper ventilation.
7. Surge Protector: Use a surge protector to protect the microwave from power surges.
