If your microwave turns on but doesn’t heat your food, the culprit is often a failed capacitor within the high voltage circuit. This small but vital component helps convert electrical current to the high voltage needed to power the magnetron, …
Why Is My Microwave Running but Not Heating, and How Can I Test the Capacitor? Read More »
Microwave sparking, or arcing, typically occurs when electromagnetic waves contact conductive materials inside the oven, such as metal objects or chipped paint exposing metal. Common causes include left-behind metallic objects, residue or damage on the waveguide cover, and compromised interior …
To test a microwave magnetron, unplug the appliance, discharge the high-voltage capacitor, and check resistance between terminals using a multimeter set to the lowest ohm setting. A normal reading is 0-5 ohms with no continuity to ground. Anything outside these …
If your microwave runs but the food stays cold, the high-voltage heating circuit is not completing. In a working unit, the control board sends AC power through fuses, thermostats, and door switches to a transformer, then a capacitor and diode …
Why Isn’t My Microwave Heating and What Causes It To Stop? Read More »
A microwave diode converts the alternating current (AC) output of the transformer to direct current (DC), nearly doubling the voltage to power the magnetron, which is responsible for heating food. If the diode is burned out, the magnetron won’t receive …
