Microwave High-Voltage Diode For: LG 6021W3B001U, 6851W1A001V, AP5632506, PS3655987

Microwave High-Voltage Diode For: LG 6021W3B001U, 6851W1A001V, AP5632506, PS3655987

ERP 6021W3B001U is a generic replacement high-voltage diode for compatible LG microwave applications. The diode supports the microwave high-voltage circuit, and a failed diode can contribute to no-heat or abnormal high-voltage operation. This is an ERP generic replacement, not a genuine LG-manufactured diode. Verify the complete microwave model, original part number, diode orientation, voltage rating, and physical fit before ordering.

Installation and Safety

Microwave high-voltage repairs are hazardous.
