Parts for Frigidaire EI30BM5CHSA: 03 - Oven / Cabinet Parts

This rectifier is the microwave's high-voltage diode. It converts AC to DC in the high-voltage circuit so the magnetron can heat. Replacing a failed rectifier can restore reliable heating performance.

• Converts alternating current to direct current in the microwave's high-voltage circuit
• Works with the transformer and capacitor to power the magnetron
• A failed rectifier can cause no heat while the unit runs, intermittent heating, or unusual humming
• Blocks reverse voltage to help protect high-voltage components

• Disconnect power before servicing; microwaves contain high-voltage circuits
• The high-voltage capacitor can retain a dangerous charge even when unplugged—discharge per service procedures
• Observe polarity and match the original orientation during installation
• Route and secure leads as originally installed to avoid arcing or damage

This damper assembly controls airflow for the exhaust vent, opening with the blower and closing when off to block backdrafts. Replace a cracked, missing, or sticking damper to restore proper venting and reduce noise and drafts.

• Opens during fan operation to let cooking air exit through the duct; closes when off to prevent outside air from entering
• Helps maintain correct airflow to capture steam, smoke, and odors
• Common symptoms: poor venting, rattling/clacking noises, cold air drafts through the unit, visible broken or missing flap
• A stuck or binding damper can cause louder fan noise and weak airflow

• Disconnect power before servicing; remove the vent cover/adapter to access the damper
• Note airflow arrow and hinge orientation; install so the flap swings freely in the exhaust direction
• Reuse existing screws and seals; replace any damaged foil tape or gaskets to prevent leaks
• After installation, run the fan to ensure the damper opens/closes smoothly without rattling
