Parts for Broan RM325H: Venting Assembly Parts

This damper is the vent backdraft flap that opens to let exhaust out and closes to keep outside air and odors from coming back into the appliance. It restores proper airflow control for venting systems. What it does:

• Opens when the fan runs to allow exhaust to flow through the vent
• Closes when the fan is off to prevent cold air, smells, and pests from entering
• Stops rattling or restricted airflow caused by a stuck or damaged flap
• Works as the airflow control element inside the vent housing or duct

• One damper assembly

• Disconnect power to the appliance before starting any repair
• Access the vent or hood housing per the appliance service instructions; removal of grille or access panel may be required
• Remove the old damper and any mounting hardware; install the new damper in the same orientation
• Check that the damper moves freely after installation and that duct connections are secure

This foam seal cushions and seals small gaps in ventilation appliances to reduce vibration, block drafts and limit dust entry. It helps restore a snug fit where worn or compressed foam is causing noise or air leaks. What it does:

• Provides a soft seal to close gaps between panels or components
• Reduces rattling and vibration caused by loose or worn parts
• Helps limit dust and unwanted airflow through seams
• Commonly used where original foam has deteriorated or compressed

• One foam seal/strip as shown

• Clean and dry mating surfaces before applying for best adhesion
• Trim to fit with scissors or a utility knife; avoid stretching the foam
• Press firmly to seat adhesive; allow any adhesive to cure per manufacturer instructions
• Disconnect power to the appliance when working near electrical components and follow all safety precautions

This strain relief is a small wire connector that protects and secures incoming power or wiring where it passes through a housing, helping prevent pull, abrasion, and exposed conductors for safer operation. What it does:

• Secures and anchors incoming cable to prevent strain on terminals and internal wiring
• Protects wiring from chafing where wires pass through metal or plastic openings
• Helps maintain reliable electrical contact by reducing stress-related intermittent connections
• Commonly needed when the original bushing is cracked, missing, or hardened and no longer grips the cable

• Always disconnect power at the breaker before accessing wiring
• Replace with the same type and size strain relief to ensure proper fit and protection
• Inspect wiring insulation and terminal condition; repair any damaged conductors before reassembly

This replacement power cord restores electrical connection to compatible range hoods and ventilation units, letting the appliance receive safe, reliable power. Use this when the original cord is damaged or fails to deliver consistent power. What it does:

• Replaces a worn, frayed, or damaged power cord to stop intermittent power or loss of power
• Provides the appliance's primary AC connection from wall outlet to unit
• Helps eliminate visible damage, sparks, or exposed wiring that can present hazards
• Returns the unit to normal operation when cord failure is the root cause

• Disconnect power at the breaker and unplug the appliance before starting any work
• Basic tools may be required; handle wires and terminals carefully to avoid damage
• Follow the appliance manufacturer's wiring diagram and terminal markings when connecting

This is a replacement mounting nut that secures hardware and components on compatible Broan appliances, restoring proper fastener retention and preventing looseness. What it does

• Fastens and secures panels, brackets, or components in place
• Prevents vibration-related loosening that can cause rattling or misalignment
• Replaces missing or damaged thread hardware for safe, reliable attachment
• Used wherever the corresponding bolt/stud requires a matching nut to hold parts together

• Disconnect power to the appliance before servicing to avoid electrical hazard
• Use the correct wrench or socket size to avoid stripping the nut or mating threads
• Thread the nut on by hand first, then snug with a tool; avoid overtightening
• Inspect mating bolt/stud and threads for damage; replace if stripped or corroded
