This fan wheel spins inside the appliance to move air through the system, restoring proper airflow for heating and cooling. It replaces a cracked, worn, or unbalanced wheel to reduce noise and improve performance. What it does:

• Circulates air through the appliance to support heating, cooling, or ventilation
• Helps maintain consistent temperatures and prevents motor overload from restricted airflow
• Reduces rattling or grinding noise caused by a warped or broken wheel
• Restores proper airflow when the original wheel is damaged or missing

• One fan wheel

• Disconnect power to the appliance before starting any repair
• Access may require removing an access panel or cabinet components; follow the manufacturer's service instructions
• Inspect the blower housing and mounting for damage; replace any damaged clips or fasteners
• Ensure the wheel spins freely and is seated correctly on the motor shaft before reassembly

This control transformer provides the low-voltage power needed for the appliance's control board and user interface, restoring reliable operation of displays, timers, and electronic controls. What it does

• Steps appliance line voltage down to the control circuit voltage so electronic controls and displays can operate.
• Commonly replaced when controls, displays, or touchpads lose power or behave intermittently.
• Helps resolve symptoms like dim or blank control displays, non-responsive touch controls, or intermittent electronic operation.
• Designed to match mounting and wiring of the original part for straightforward replacement.

• One transformer assembly as shown.

• Turn off and unplug the appliance (or shut off circuit breaker) before servicing to avoid electrical shock.
• Verify wiring locations and take a photo before disconnecting; reconnect matching each terminal.
• Inspect associated fuses and connectors; replace any damaged wiring or connectors during installation.

The Electronic Control is an OEM part for Whirlpool countertop microwaves. Housed discreetly within the control panel, it powers intuitive touch buttons and LED displays enabling customized cooking functions and settings.

Causes of control failure frequently stem from water damaging short-circuiting delicate pathways or dislodging internal connections over repeated use. Physical impact accidents may also fracture circuit boards.  

Symptoms of a faulty electronic control include:

• Nonresponsive buttons that do not initiate cooking presets
• Blank or ghosted LED displays that do not update  
• Abnormal buzzing or clicking noises emitting from controls
• Inability to toggle between power levels and time settings

Compatible models also include those by Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and Kenmore. 

This air deflector redirects airflow inside the appliance to help maintain proper circulation and protect components from direct airflow. Replacing a damaged deflector restores intended air paths and can reduce uneven temperature or noise. What it does

• Guides air where the manufacturer intended to ensure even circulation.
• Protects nearby components from direct airflow and wear.
• Helps reduce symptoms like uneven cooling/heating or unusual airflow noise.
• Works as a passive airflow-management part — no electrical connection.

• Disconnect power to the appliance before starting any repair.
• Handle the deflector carefully to avoid cracking plastic tabs during removal or installation.
• Installation typically requires basic hand tools; for exact steps.

This electronic control board is the main console module that manages your appliance's cycles, settings and display so controls respond correctly and programs run as selected. Replacing a faulty board restores normal control operation. What it does:

• Controls cycle selection, timing, and start/stop functions for the appliance
• Manages the user interface and display so buttons and indicators respond
• Communicates with other modules to run selected programs and safety checks
• Common symptom link: appliance won't start, display is blank or shows errors
• Common symptom link: buttons or touch controls don't respond or cycles won't advance

• One electronic control board (console module)

• Disconnect power before starting any service work to avoid shock
• Handle the board by edges and avoid touching components or contacts
• Verify all wiring harnesses and connectors seat fully before reassembly

The Support Bracket (WHT) is an OEM part for Whirlpool over-the-range microwaves. It serves as a mounting bracket to securely install the microwave in its space above the cooktop. 

Causes of a bad Support Bracket (WHT) can include cracks or breaks over many years holding the weight of the microwave. Vibrations from cooking below may also weaken or damage its structural integrity.

Symptoms of a bad bracket support include: 

• An unstable or insecure microwave installation
• Inability to properly level or adjust height 
• Possible injury concerns if the microwave dislodges

This genuine Whirlpool replacement is compatible with additional brands such as Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore as well.

This wire harness routes power and signals between key components for consistent performance. Replacing a damaged harness restores reliable connections and correct operation of affected controls, motors, or sensors.

• Distributes electrical power and control signals between boards, switches, sensors, and motors
• Replaces cut, brittle, burned, or corroded wires and terminals that cause connection faults
• Common symptoms include intermittent operation, a component that won't run, or error codes related to poor connections
• Restores proper wire routing when installed in the factory path and secured with clips/ties

• Disconnect power before servicing; turn off water or gas supply if applicable
• Photograph and label existing connections; move plugs one at a time to the new harness
• Route along the original path; secure in clips/ties and keep clear of sharp, hot, or moving parts
• Seat each connector fully by the plug body (do not pull on wires); inspect mating terminals for heat damage

This motor cover shields the motor assembly and nearby components from debris and accidental contact. Replacing a cracked or missing cover restores proper protection and can reduce noise caused by objects rubbing against moving parts.

• Covers the motor area to block dust, grease, and foreign objects
• Helps secure the motor housing and maintain proper clearances
• Can quiet rattling or scraping caused by a loose or broken cover
• Common signs: cracked, warped, or missing cover; scraping/rattling from the motor area; visible motor exposure

• Disconnect power at the breaker or unplug the appliance before servicing
• Access the motor compartment per your model's service/installation information
• Retain and reuse the original screws/fasteners unless damaged
• Do not overtighten fasteners to avoid cracking the new cover; verify clearances before testing

This support is a replacement mounting bracket that helps secure internal components and keeps assemblies aligned for proper operation. Installing a new support can reduce movement, rattling, or misalignment of the attached parts. What it does:

• Holds and stabilizes a component or assembly inside the appliance
• Prevents excess movement that can cause vibration or noise
• Keeps parts aligned to ensure smooth mechanical operation
• Helps maintain proper spacing between connected parts to avoid wear

• Disconnect power (and water, if applicable) before beginning any repair
• Use appropriate hand tools; avoid overtightening mounting screws
• Wear safety gloves and eye protection; handle sharp sheet-metal edges with care

This evaporator fan motor circulates cold air through the freezer and refrigerator compartments to maintain even temperatures and consistent cooling. Replaces a failed or noisy motor to help restore airflow and temperature stability. What it does:

• Spins the evaporator fan blade to move cold air across the evaporator and into the cabinet.
• Helps prevent warm spots and uneven cooling when operating correctly.
• Commonly replaced for noisy operation, failure to run, or intermittent airflow.
• Compatible with refrigerators that use this OEM-style fan motor design.

• Disconnect power to the appliance before starting any repair.
• Access typically requires removing interior panels or the evaporator cover; keep screws and fasteners organized.
• Inspect the fan blade and housing for ice buildup or obstructions before installing the new motor.
