This is a fan blade that attaches to the motor shaft inside the microwave to circulate air for cooling internal components. It helps prevent the magnetron and other electronics from overheating during operation. Replace this blade if it is cracked, broken, or warped, or if the microwave is running louder than normal or overheating during use.

This capacitor stores and releases electrical energy to help power your microwave's magnetron and other components. It works with the transformer to provide the high voltage needed for microwave operation. If your microwave won't heat food, makes unusual noises, or trips circuit breakers, a faulty capacitor is often the cause.

This is a high voltage diode wire assembly used in the microwave's power circuit. It works with the capacitor and magnetron to convert electrical current and generate microwave energy for cooking. Replace this part if the microwave runs but does not heat, or if the diode has visibly burned or shorted out.

Microwave not heating but still running? The magnetron controls heating function. DIY repair in under 2 hours with basic tools and multimeter testing.

Microwave won't turn on or has no power? A blown fuse is often the cause. This safety fuse protects circuits from shorts. Requires cover removal to replace.
