Product Description

The Frigidaire 5304478954 Microwave Capacitor Rectifier Kit regulates and converts electrical current to supply the high-voltage components needed for cooking. It performs by converting alternating current to direct current while storing a charge to power the magnetron. It is located inside the microwave's high-voltage circuit and is securely wired to the transformer and diode, allowing current to be converted into DC and to run without fault to the electrical system inside the appliance's high-voltage system.
