General Electric Microwave Damper & Related

This damper is the exhaust vent flap for a microwave. It opens to let air flow out while venting and closes when the fan is off to help prevent drafts, moisture, and debris from entering the unit.

• Directs airflow from the microwave to the outside or recirculation duct
• Helps prevent backflow of air and odors when the fan is off
• A common cause of rattling noises, poor venting, or backdrafts during operation
• Replaces a warped, stuck, or missing vent flap to restore proper ventilation

• Disconnect power before servicing
• Access is typically from the top or rear once the unit is removed or tilted forward
• Note airflow direction and hinge orientation before removal
• Ensure the flap moves freely after installation and proper airflow

The Hood Damper Assembly is an OEM part for GE microwave ovens. This part controls the flow of exhaust air to minimize odors and smoke from cooking. This damper opens to allow air to vent outside during microwave operation and closes to prevent outside air from entering when the microwave is not in use.

Causes of a bad hood damper assembly can include mechanical failure such as a stuck or broken damper, deterioration of the linkage or springs that operate the damper, and blockage caused by grease or debris accumulation, which can impair its functionality.

Symptoms of a bad Hood Damper Assembly include:

• Ineffective venting of smoke or cooking odors
• External air leakage into the microwave system
• Unusual noises during operation indicating a damper misalignment or obstruction

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Damper is an OEM part for GE microwaves. This part controls the airflow within the microwave, allowing steam and hot air to be vented properly during cooking. The damper opens and closes to regulate the release of excess moisture and heat, ensuring optimal cooking performance and preventing overheating.

Causes of a bad damper can include wear and tear from regular use, buildup of grease or food particles, or mechanical failure.

Symptoms of a bad damper include:

• Excessive steam or heat buildup inside the microwave
• Unusual noises during operation
• The microwave overheating or shutting down unexpectedly
• Inconsistent cooking results

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

This is an authentic OEM replacement waveguide sourced directly from the manufacturer. Waveguides are used in microwave ovens to help transmit the radiation throughout the microwave's inner cavity. The waveguide also protects the microwave's inner parts from damage due to steam or spattering food during operation. If the waveguide breaks or cracks, as can happen to plastic parts over time, it should be replaced to protect the mechanical workings of the microwave. Although the microwave can be used without the waveguide, it is not recommended.The waveguide is located inside the cooking area of the microwave over the control panel. It is a thin piece of material that may resemble cardboard. To start, disconnect the microwave from the wall outlet and use a screwdriver to remove the two screws holding the waveguide in place. Discard the broken waveguide and use the screws from the original waveguide to install the new one. Plug the microwave back into the outlet. This waveguide is made of durable plastic and is sold individually. This waveguide does not come with screws. It is designed for use in microwave ovens manufactured by General Electric.

This molded resin cover is a protective plastic shield used inside the microwave. It helps protect internal components and ducting from splatter and debris and restores a secure, finished fit when the original cover is cracked or missing. What it does:

• Shields internal components from grease, steam, and food splatter inside the unit
• Helps maintain proper airflow paths and a snug, rattle-free fit
• Common replacement when the original cover is cracked, warped, loose, or missing
• Visual cue: exposed internal parts or a cover that won't stay secured

• One resin (plastic) cover

• Disconnect power (unplug or switch off the breaker) and allow the unit to cool
• Access the cover location; remove retaining screws/clips and keep hardware for reuse
• Align the new cover and secure it without overtightening
• Ensure the cover is fully seated and not contacting nearby moving parts before restoring power

This upper duct directs exhaust and airflow inside the appliance to help proper ventilation and heat management. It replaces a damaged or warped upper duct to restore correct internal airflow paths. What it does:

• Channels exhaust and internal airflow between the cooktop/vent area and the vent housing
• Restores proper airflow if the original duct is cracked, bent, or blocking ventilation
• Helps reduce unusual smells or cooking smoke reaching cabinetry by maintaining the exhaust path
• Works as a structural guide for adjacent panels and components in the vent area

• Follow the appliance service manual for disassembly steps and correct reinstallation order
• Disconnect power (and gas if applicable) before servicing to avoid shock or injury
• Use appropriate hand tools; avoid overtightening fasteners that can crack the duct or mounting tabs

This rear duct assembly channels exhaust and airflow at the back of the appliance to help maintain proper ventilation and consistent cooking performance. It replaces a damaged or rusted rear duct to restore correct air routing and safety. What it does:

• Directs exhaust and ventilation from the oven cavity to the appliance rear outlet
• Prevents hot air from escaping into adjacent components, reducing heat-related wear
• Helps maintain even temperature distribution and consistent cooking results
• Addresses symptoms like visible duct damage, rattling at the rear, or disrupted exhaust flow

• Intended for rear-panel installation; follow your appliance service manual for exact procedure
• Disconnect power and gas before beginning any repair
• Use correct fasteners and gaskets from the OEM parts list when reinstalling

This molded air tunnel directs heated air from the blower through the dryer drum for consistent airflow and efficient drying. Replaces a cracked or damaged duct to restore proper air circulation and help improve drying performance. What it does:

• Channels blower air into the drum and toward the lint screen and exhaust
• Prevents airflow loss from gaps or cracks that can reduce drying efficiency
• Helps maintain proper ventilation to reduce overheating and extended dry cycles
• Fits into the dryer's internal plenum to keep airflow focused and consistent

• One air tunnel/drying airflow duct

• Disconnect electrical power (and gas supply for gas dryers) before beginning service
• Access typically requires removing the dryer front panel or cabinet
• Align the tunnel with the blower housing and drum opening, then secure with the original fasteners or clips
• Check for a good seal around mating surfaces and reassemble panels before testing
