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 control regulates the flow of cold air from the freezer into the fresh food compartment, helping maintain steady temperatures. Replacing this assembly restores proper airflow and consistent cooling.

• Opens and closes the air door to meter cold air from the freezer into the refrigerator
• Helps maintain the set temperature and even cooling across shelves
• Common failure signs: fresh food section too warm or too cold, weak/no airflow, clicking or grinding from the damper area
• Visible damage or a door stuck in one position can indicate replacement is needed

• Disconnect power before servicing
• Access the damper in the refrigerator control/air duct area; remove covers and retain screws per your model
• Transfer any mounting hardware or seals from the old assembly if needed
• After installation, ensure the door moves freely and allow up to 24 hours for temperatures to stabilize

The Damper Cover Assembly is an OEM part for GE refrigerators. It covers and protects the damper, which controls the airflow between the freezer and refrigerator compartments. By regulating this airflow, the damper ensures that both sections maintain their proper temperatures, contributing to optimal food preservation.

Issues such as wear and tear, accidental impact, or warping can compromise its functionality, leading to problems with temperature regulation within the refrigerator.

Symptoms of a bad damper cover assembly include:

• Inconsistent temperatures in the refrigerator or freezer
• Frost buildup in the refrigerator compartment
• Unusual noises from the damper area
• Refrigerator running continuously or not cooling effectively

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

When the damper control assembly fails, you'll know it. It will be stuck in one of two positions - closed or open. If it's stuck closed, your refrigerator compartment won't cool down at all and things will start to warm up. But if it's stuck open, too much cold air will rush in and your food will start freezing over. The damper control cannot be fixed and will need to be replaced.

The air damper monogram kit is used in refrigerators that include freezers. The main purpose of this component is to balance the way air flows when it leaves the evaporator fan housing. The device will often control how much cold air is moved into the fresh air compartment. It can also be used to move cold air from the refrigerator into the freezer. If this part is damaged, cold air may not go where it should and some parts of the refrigerator may become too warm.If this part is damaged or not working, it should be replaced. Disconnect the refrigerator from power and open the door to find the air damper monogram. It is located where the cold air enters the fresh food area. Access the housing and inspect it for damage. It can be removed to get to the damper components. Check the sensing bulb for issues before removal. Install all parts of the kit or only the ones that are damaged before reassembling the appliance.This is a genuine OEM air damper monogram kit for use with General Electric refrigerators. It is priced individually and sourced straight from the manufacturer.

• Some models require calibration or programming after installation—follow the tech sheet/service manual

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.

The air diffuser is the damper assembly that meters cold air from the freezer into the fresh food compartment. Replacing a sticking or broken diffuser restores proper airflow and helps keep refrigerator temperatures balanced and consistent.

• Regulates and directs airflow from the freezer to the refrigerator compartment
• Opens and closes to balance temperatures between sections
• Helps prevent warm spots or freezing near vents in the fresh food area
• Typical symptoms: refrigerator too warm, items freezing near vents, continuous or no airflow through the diffuser, or frost buildup around the diffuser opening

• Disconnect power before servicing
• Access from the fresh food section; remove shelves and the diffuser cover/grille to reach the assembly
• Transfer any reusable mounting hardware or seals from the original part
• Restore power and allow up to 24 hours for temperatures to stabilize; verify airflow through the diffuser

This diffuser—often called the refrigerator air damper—controls how much cold air flows from the freezer into the fresh food compartment. Replacing a worn diffuser helps restore even cooling and more stable temperatures throughout the refrigerator. What it does:

• Opens and closes to regulate airflow from the freezer to the refrigerator
• Helps maintain set temperatures and reduce warm spots or over-cooling
• Common symptoms: fresh food too warm while freezer is OK, food freezing on shelves, weak airflow from upper vents, or clicking/buzzing from the diffuser area
• Helps address frost or condensation near the diffuser outlet

• 1 diffuser

• Disconnect power before servicing
• Access from the refrigerator section; remove shelves/air duct covers as needed
• Note wiring and orientation; remove mounting screws/clips and transfer any seals/insulation if present
• After installation, restore power and allow up to 24 hours for temperatures to stabilize
