What To Do When Your Microwave Is Not Heating

What’s not to love about microwaves? They defrost frozen food quickly, preserve nutritional value, use less energy than conventional ovens, and make preparing meals so much easier. When your microwave suddenly stops heating, it can be pretty inconvenient. While many people think a non-heating microwave means it’s time for a replacement, that’s not always the case. Here’s why.

How Do Microwaves Work?

Microwaves are one of the most convenient kitchen appliances ever invented. To heat food, they use an electron tube to turn electricity into electromagnetic waves that reflect off the microwave’s metal interior. Food and drinks absorb the waves and heat up, but that doesn’t mean they cook food from the “inside out.”

Instead, microwaves “stimulate” a food’s molecules, causing them to spin, vibrate, clash, and heat up. As the food’s outer layers heat and cook, inside layers cook primarily by the heat conduction from the hot outer layers. One of the biggest misconceptions about microwave ovens is that they make food radioactive. The truth is they’re more energy-efficient and often safer than conventional cooking methods because your food cooks faster, and the energy heats only the food.

Can You Repair a Microwave That Isn’t Heating?

Anything from a faulty door switch to a defective main control board can cause your microwave to stop working correctly. While a microwave that doesn’t heat is pretty much useless, the good news is that it’s often a fixable problem.

The two most common reasons a microwave stops heating are:

  • An issue with the appliance’s high voltage diode that provides power to the magnetron.
  • A faulty magnetron, which produces the heat a microwave needs to cook and heat dishes.

Faults with either of these parts can prevent your microwave from producing heat, even when it’s receiving power. Both parts can be replaced, but because they’re not easy to access, it’s often helpful to call in a qualified microwave repair service to handle the issue safely and properly.
