The inverter box assembly is the enclosure that houses and protects the appliance's inverter/control electronics, helping ensure reliable power conversion for variable-speed motor operation and secure mounting of wiring and components. What it does:

• Provides a protective housing and mounting for the inverter/control electronics.
• Routes and secures wiring and plug connections to the inverter board.
• Helps prevent moisture, dust, and vibration-related damage to control components.
• When damaged or cracked, may cause intermittent motor operation, error codes, or loss of variable-speed function.

• Disconnect power to the appliance before starting any repair.
• Handle electronic components carefully and avoid static discharge; use ESD precautions if available.
• Inspect connectors and wiring for damage before reinstalling; replace damaged connectors or harnesses as needed.
• Follow for proper removal, routing, and fastening of the assembly and for torque/spec details.

This compressor mounting grommet kit replaces worn or damaged rubber mounts that secure the compressor and reduce vibration. Restoring proper mounts helps cut down on compressor noise and prevents movement-related wear. What it does:

• Cushions and isolates the compressor to reduce vibration and rattling noise
• Keeps the compressor secured to its mounting bracket during operation
• Helps prevent stress and wear on mounting hardware and tubing
• Addresses symptoms like excessive vibration, banging, or unusual compressor noise

• Disconnect power to the appliance before beginning any repairs
• Support the compressor while removing and installing mounts to prevent strain or shifting
• Use appropriate hand tools and avoid over-tightening fasteners that can compress or damage grommets

This refrigerator compressor is the heart of the sealed cooling system. It compresses and circulates refrigerant so the fresh food and freezer sections reach and maintain set temperatures, restoring cooling performance when the original unit has failed.

• Compresses and moves refrigerant through the evaporator and condenser to remove heat from the cabinet
• Restores cooling when a failed or seized compressor is the cause of no-cool/weak-cool conditions
• Symptoms include a warm refrigerator or freezer, extended run time with little cooling
• Clicking or humming from the compressor area with no start, or overheating and cycling on overload

• Sealed-system service requires EPA Section 608 certification, recovery equipment, brazing, deep vacuum, and precise recharging
• Disconnect power and properly recover refrigerant before opening the system; replace the filter-drier, braze with nitrogen purge, leak-test, evacuate, then charge to the specification on the model's data plate
• Transfer any model-specific grommets, brackets, tubing, and external inverter/start components from the original unit or replace as directed in the service manual

This electronic control board is the refrigerator's central control module, coordinating cooling and defrost functions for stable temperatures. Replacing a failing board helps restore proper operation of the compressor, fans, and related circuits.

• Regulates cooling by switching the compressor and fans based on sensor input
• Controls and times the automatic defrost cycle to prevent frost buildup
• Supplies logic and power to temperature controls and indicators
• Can cause no-cool, intermittent cooling, constant running, or unresponsive controls when faulty

• Disconnect power to the refrigerator before servicing
• Handle the board by the edges and use ESD protection if available
• Photograph/label connectors and transfer wiring one at a time
• Some models require control setup or calibration—follow the appliance's service instructions

• Disconnect power at the breaker or unplug the appliance before servicing to avoid shock or injury.
• Access the terminal area; ensure terminals are cool and dry before handling.
• Align cover over the terminal block and secure according to the OEM design; replace any damaged fasteners with correct OEM parts.
• If you see burn marks, melted insulation, or loose terminals, replace or repair the affected wiring/terminal block before installing the cover.

This electronic control board is the main printed circuit board that manages the appliance's functions and user commands, restoring proper cycle selection and electronic control when the original board fails. What it does:

• Receives input from the user interface and directs motors, valves, and timers to run selected cycles.
• Replaces a faulty or unresponsive control that causes no display, unresponsive buttons, or cycles that won't start/advance.
• Helps resolve intermittent or erratic operation caused by damaged or corroded circuitry.
• Works with the appliance's sensors and actuators to maintain programmed cycle sequences.

• One electronic control board (main control PCB) as pictured.

• Disconnect power to the appliance before beginning any work to avoid electrical shock.
• Handle the board by the edges and avoid touching contacts to prevent electrostatic damage.
• Some models require removal of panels or control console; for access.

Size: 1/4 inch hex head, 10-12 x 1/2 inch.

This condenser coil removes heat from the refrigerant so your refrigerator can cool efficiently. Replacing a damaged or clogged condenser restores proper heat dissipation and can reduce excessive run time and poor cooling. What it does

• Releases heat from the sealed refrigeration system so the fridge can maintain set temperatures
• Helps the compressor run less frequently when operating normally
• A cracked, bent, or clogged condenser can cause poor cooling or warm interior temperatures
• Excessive dust or debris on the condenser may lead to higher energy use and longer run cycles

• Disconnect power to the appliance before starting any repair
• Access may require moving the refrigerator and removing the rear or lower access panel
• Coils and edges can be sharp—wear gloves and eye protection

Size: 8-32 x .312 inch.

The Condenser Fan Motor is an OEM part for Whirlpool brand bottom-mount refrigerators. This motor powers the condenser fan which dissipates heat from the refrigeration system coils, maintaining cool interior temperatures.

Causes of failure include normal bearing wear from continuous rotations, or buildup obstructing free blade movement. 

Symptoms of a faulty motor include:  

• Elevated interior temperatures and frost propagation issues   
• Extended run times and higher energy consumption
• Grinding or buzzing noises emanating from the refrigeration system area

This Whirlpool replacement restores efficient heat removal and preserves food freshness. Compatible with KitchenAid, Maytag, and some Kenmore models too, it prevents future repair bills.
 

This condenser fan blade mounts to the fan motor and pulls air across the condenser coil and compressor. Replacing a cracked or warped blade restores airflow so your refrigerator cools efficiently and the compressor runs at a safe temperature.

• Circulates air through the condenser coil and over the compressor to remove heat
• Helps maintain cooling performance and stable system pressures
• Common symptoms: weak or no airflow at the rear/base, rattling or scraping noises, wobble/vibration, visible cracks or missing fins, warmer-than-normal compartments or hot cabinet sides
• Works with the condenser fan motor and shroud; typically replaced when the hub is stripped or the blade is damaged

• Disconnect power and pull the refrigerator out; remove the rear access cover near the compressor
• Note blade orientation and depth on the motor shaft before removal
• Pull the old blade straight off; press the new blade onto the shaft until fully seated and ensure it spins freely with proper shroud clearance
• Reinstall the cover, restore power, and verify strong, quiet airflow

• Provides a dedicated service disconnect for safe maintenance and resets
• Common symptoms: no power, intermittent shutdowns, or the unit won't stay on unless the switch is held/positioned
• Visual clues: broken actuator or heat-discolored/loose terminals

• Power disconnect switch only

• Disconnect power at the breaker before servicing
• Access the switch location; on many built-in units it's behind the top grille or control panel
• Move wires one at a time to the new switch to maintain correct orientation
• Restore power and verify the switch cleanly turns the unit on and off

Screw: 8-16 x 3/8 inch.

This electronic power supply board converts incoming AC power to the low-voltage DC used by the refrigerator's controls and components. Replacing a failed board restores stable power to the UI, fans, lights, and cooling functions.

• Converts line voltage to regulated low-voltage DC for control electronics
