Cross Reference Information

Part Number ACV73430101 replaces AP6028045.

Description

This damper assembly mounts at the microwave's exhaust outlet to direct airflow outside and block backdraft when the fan is off. Replacing a cracked or warped damper restores venting performance and helps reduce drafts and rattling noise.

• Opens with blower airflow and closes when off to help prevent outside air from entering through the duct
• Directs steam, smoke, and cooking odors to the exhaust path
• Helps reduce drafts/backdraft when the fan is not running
• Common failure signs: weak venting, flap stuck open/closed, or rattling/flapping noises

What's included: 1 damper assembly Install notes:

• Disconnect power at the breaker; if over-the-range, support the unit per manufacturer instructions
• Remove the vent grille/top cover to access the outlet and take out the old damper; reuse existing hardware as needed
• Match the new damper's orientation to the original so the flap opens with airflow and moves freely
• Beware sharp sheet-metal edges; wear cut-resistant gloves and test the fan after reassembly to confirm proper operation
