Microwave Oven Repair: What to Know When Your Microwave Stops Working

Microwaves have become an essential part of most households, making it easy to heat food, defrost ingredients, or even cook full meals in minutes.


But when your microwave suddenly stops working, sparks inside, or refuses to heat anything, it’s more than just an inconvenience—it’s a disruption to your routine.


That’s where microwave oven repair comes in. At Twin City Appliance, we help homeowners get their microwaves back in working order quickly and affordably. Whether your microwave won’t turn on, has a faulty keypad, or just isn’t heating properly, we’re here to help.

Common Microwave Problems We Fix


Microwaves may seem simple on the surface, but they contain a combination of electronic, mechanical, and high-voltage components. Here are some of the most common issues that call for professional microwave oven repair:


1. Microwave Not Heating


One of the most frustrating issues is when your microwave turns on but doesn’t heat your food. If you’ve ever searched for how to repair microwave oven not heating, you’re not alone. This is usually caused by a faulty magnetron, capacitor, or diode—components that should only be handled by a trained technician.


2. Turntable Not Spinning


If your microwave’s turntable has stopped turning, it can lead to uneven cooking or heating. The issue could be as simple as a broken turntable motor or a worn-out roller guide.


3. Microwave Won’t Start


Pressing the start button and getting no response? This could point to problems with the door switch, fuse, or control board. These are sensitive parts, and attempting a DIY repair can be risky without proper tools and knowledge.


4. Strange Noises


Loud humming, buzzing, or clicking noises could indicate a malfunctioning motor or magnetron. Ignoring these noises could lead to bigger problems—or a complete breakdown.


5. Sparks or Burning Smell


Seeing sparks inside your microwave is never a good sign. This could be caused by a damaged waveguide cover or metal objects left inside. If you detect a burning odor, unplug your microwave immediately and call in a technician.


When to Call a Professional vs. When to DIY


There are a few minor microwave issues you might be able to troubleshoot on your own, such as:


  • Replacing the interior light bulb

  • Cleaning the turntable or microwave cavity

  • Resetting the unit if it has a digital control panel

But for more complex issues—especially those involving microwave oven repair of electrical components—it’s always best to leave it to professionals like us at Twin City Appliance. Microwaves can store high voltage even when unplugged, making DIY repairs dangerous without the right experience.


If you’re searching online for microwave repair near me, it’s likely time to call in trusted local experts.

Why Your Microwave Might Not Be Heating—and What to Do About It


Microwaves rely on a part called the magnetron to produce the electromagnetic waves that heat your food. If the microwave runs but doesn’t warm anything, it’s usually the magnetron or one of its supporting components that’s failed.


Other possible causes include:


  • A burned-out high-voltage diode


  • A faulty door switch preventing proper activation


  • Issues with the thermal fuse or high-voltage capacitor


If your search history includes how to repair microwave oven not heating, chances are these are the types of repairs you're looking at—repairs that should be handled by an experienced technician. Attempting to open or troubleshoot high-voltage parts can be extremely dangerous without the proper training.

Tips to Extend the Life of Your Microwave


While professional microwave oven repair can restore your appliance, taking good care of it can help avoid future issues. Here are a few quick tips:


  • Keep it clean: Wipe down the inside regularly to prevent food buildup that can damage components.
  • Avoid metal: Never place metal or foil inside, even by accident.
  • Use microwave-safe containers: Some plastics can melt or warp, releasing fumes.
  • Don’t slam the door: Repeated slamming can damage the door switch.
  • Don’t run it empty: Running a microwave without anything inside can damage the magnetron.
