Examining the diode is just one of the steps you can take to diagnose why your microwave isn’t heating up correctly. However, if you don’t feel comfortable dealing with the device’s interior, the safer option is to have a professional troubleshoot and repair your microwave.

Examine the Capacitor

When a microwave is not heating up, one of the potential culprits could be a faulty capacitor. The capacitor plays an essential role in supplying the high voltage needed for the magnetron to produce microwaves. If the capacitor is not functioning as it should, then the microwave won’t be able to heat up food properly.

To examine the capacitor, first, unplug the microwave and discharge the capacitor before proceeding. The capacitor is usually located near the magnetron and has a cylindrical shape with wires attached to its terminals. Here are some steps to follow:

  • Check for visible signs of damage: Inspect the capacitor for any signs of burns, cracks, bulges, or leaking fluid. If you find any of these signs, then you need to replace it with a new one.
  • Test the capacitor with a multimeter: Set your multimeter to the capacitance setting, then discharge the capacitor and remove it from the appliance. With the multimeter leads, touch the capacitor terminals to test it. A good capacitor should read the capacitance value listed on the capacitor itself, which can also be found in the microwaveโ€™s manual. If your multimeter displays a zero reading or a significantly lower value, then it means that your capacitor is faulty and needs replacement.
  • Replace the capacitor: If the capacitor is found to be defective, you can easily replace it. Look at the manual or search for your microwave’s model number online to find the correct replacement part. When you have the new capacitor, plug it into the same connectors where the old one was attached. Make sure that you wear gloves and take all necessary safety precautions when installing the new capacitor.
