Safety note

Before troubleshooting your microwave issues, it’s important to be aware of some dangers involved in microwave repair. While most appliances are safe when disconnected from their power source, microwaves are not. 

They contain a part called a high-voltage capacitor, which retains its charge even when unplugged. Touching the capacitor while performing repairs can cause serious electric shocks and even death. 

It’s also important to be aware of the risks regarding radiation. Microwaves are built with a shield that prevents the electromagnetic radiation from escaping. If you accidentally damage that shield during your repairs, it can cause radiation to leak out while the microwave is running. Over time, this radiation can be harmful to your health. Incorrectly performed repairs can also increase the chance of a fire starting inside your microwave. 

Due to these risks, we recommend only performing repairs on parts of the microwave that are not near the high-voltage capacitor. It’s also essential to seek professional help if there is anything you’re not sure of. 

Microwave not heating

A microwave that isn’t heating properly is one of the more common microwave issues you might encounter. If your GE microwave isn’t heating your food properly, check the following:

  • Make sure your microwave is properly plugged in and that the outlet works. You can test the outlet with a different appliance to make sure it’s functional. 
  • Ensure that the settings are correct—for example, if your microwave is on the defrost setting, it may be heating your food very slowly compared to if it’s on the cook setting. 
  • Check the door is closed: all models of GE microwaves will not operate if the door is open, so ensure the door is firmly closed. 
  • Look up any error codes: If your GE microwave is displaying an error code, search your user to find out what it means. 

Display not turning on

Another common issue you might experience with your GE microwave is a display that won’t light up or turn on. If this is your issue, make sure you check the following:

  • Ensure that the microwave is firmly plugged into the outlet. 
  • Ensure that the outlet is working properly. Plug another appliance that you know is working into the outlet and test it. 
  • If the outlet appears to not be working, check the circuit breaker to ensure it is on. If any of the breakers have tripped, reset them then try again. 
  • If you’re certain that the power is functioning, a display that isn’t turning on could indicate a problem with the display panel itself. If you are qualified, you can source replacement parts online and then replace them yourself. 

Turntable not rotating

If your microwave appears to be heating and cooking your food, but the turntable is not turning, don’t panic! This is a pretty common issue that is usually pretty simple to fix. A malfunctioning turntable can lead to uneven cooking and burned spots in your food—here’s how to fix it:

  • Make sure the glass platform is properly positioned on the turntable mechanism. Even a slight misalignment can prevent it from rotating. 
  • Ensure the roller ring, the plastic ring underneath the glass tray, is properly positioned. 
  • Ensure no food debris obstructs the roller ring or the turntable mechanism. If unsure, try thoroughly cleaning your microwave’s interior and testing it to see if the tray can rotate properly. 
  • If you feel comfortable doing so, use a multimeter to test whether the drive motor is functional, and if necessary, replace the motor with a new part. 

Door latch issues

All models of GE microwaves are designed to prevent the microwave from running when the door is open. This prevents harmful microwave radiation from escaping into your home and potentially causing health problems. However, if something is obstructing the latch mechanism, it can make the door register as being open, even if it looks to be fully closed. Here’s how to troubleshoot this issue:

  • Inspect and thoroughly clean the door latch with a microfiber cloth and a mild detergent, then test to see if the microwave is working. 
  • Check to see if the latch itself appears broken or damaged—if it is, it will need to be replaced. 
  • Make sure the door is properly aligned, as even a slight misalignment can mean it registers as being open. If it is misaligned, adjust the hinges until it closes properly. 

When to seek professional help

As discussed above, DIY microwave repair can be dangerous due to the risk of electrocution. If your microwave is experiencing one of the following issues, make sure you call a professional:

  • Your microwave is experiencing heating issues, and you’ve ruled out a problem with the power outlet or the circuit board. 
  • Your microwave is heating unevenly or overheating. 
  • Your microwave is sparking for no obvious reasons, or you notice smoke or unusual smells. 
  • There are visible cracks in the microwave’s exterior—this could allow dangerous microwave radiation to escape. 
  • Your microwave is making unusual noises, and you’ve ruled out a problem with the turntable.
