This electronic control board is the appliance's central controller. It interprets user inputs and sensor feedback, then switches power to the correct components at the right time so everyday functions operate predictably and safely.

• Coordinates appliance operations by managing timing, logic, and sequencing
• Interprets signals from the user interface and sensors to execute commands
• Switches power to loads via onboard relays
• Monitors for faults and stores or displays error codes when issues are detected
• Common failure signs: unresponsive controls/display, won't start or run, intermittent shutdowns, functions not activating, or recurring error codes after other causes are ruled out

• Disconnect power at the breaker before servicing; verify no voltage is present
• Use ESD protection; handle the board by the edges and avoid flexing it
• Photograph connectors and move wires one at a time to the matching terminals
• Transfer any model-specific jumpers, brackets, or covers from the original as directed; run the unit's diagnostic/calibration routine if required by the tech sheet

This wire harness routes power and signals between an appliance's control and internal components to restore reliable electrical connections. Replacing a damaged harness helps stop intermittent operation and power loss for safer, more consistent performance. What it does:

• Routes power and control signals between the control board and internal components.
• Replaces frayed, cut, or burned wiring that can cause intermittent operation or component failures.
• Helps address symptoms such as loss of power to controls, unresponsive cycles, or devices that won't start.
• Prevents loose or corroded connections that can create intermittent faults.

• Always disconnect the appliance from power (unplug or switch off circuit breaker) before servicing.
• Match each connector to its mating plug and follow the OEM wiring diagram for routing and color codes.
• Secure the harness away from heat sources and moving parts; use existing clips and fasteners.

Replace aging or leaking washer supply lines with this fill hose kit. It provides two 5-foot hoses to connect your home's hot and cold water valves to the washer, helping maintain a secure connection and consistent filling.

Note: This is a kit of 4 shipping bolts.

This air trap assembly replaces the factory air trap that helps control air in the refrigerator water line, restoring steady water flow to the dispenser and ice system for more reliable fills and reduced sputtering. What it does:

• Creates a controlled air pocket in the water line to prevent sputtering or intermittent flow at the dispenser and ice maker.
• Helps maintain consistent water delivery so the ice maker can fill reliably.
• Reduces the chance of air-related filling issues and noisy gurgling from the water line.
• Fits into the appliance's water plumbing as a dedicated inline assembly.

• Always unplug the appliance and shut off the water supply before beginning service.
• Inspect tubing and fittings for damage; replace any brittle or cracked lines to ensure a leak-free connection.
• Use hand tools; avoid overtightening fittings which can damage the part or tubing.
• After installation, restore water and power, run several dispense/fill cycles, and check all connections for leaks.

This replacement hose restores a sealed, reliable path for water or air inside your appliance. Swapping a worn or cracked hose helps stop leaks and corrects performance issues so cycles fill, wash, and drain the way they should.

• Routes water or air between internal components to maintain proper operation
• Maintains a sealed connection to help prevent leaks
• Kinks, cracks, or clogs can cause water under the unit, slow/no fill, or drain problems
• Replacing a damaged hose helps restore normal cycle performance

• Disconnect power and shut off the water supply before servicing
• Place towels or a shallow pan to catch residual water
• Note original routing and clamp locations; transfer clamps if reusable
• Fully seat the hose on each fitting, secure per OEM guidance, and test for leaks after installation

The Control Panel is an OEM part for Whirlpool washing machines. Located at the top of the washer, it contains an interface that enables the selection of cycles, temperatures, spin speeds, and additional settings. 

Causes of failure can include cracks developing from repeated impact or splash exposure over time. Moisture into electronic circuits is also common.

Symptoms of a bad control panel include:

• Non-responsive buttons or touchpoints
• Illegible or distorted screen display  
• Inability to select desired cycles/options
• Control panel stopping cycles prematurely

Replacing with the OEM Whirlpool part restores full operational capability. The precise fit and engineering ensure cycle programs execute as intended.

This replacement control panel is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore washing machine models.

This outer trim panel cover replaces a cracked, broken or missing exterior cover to protect internal components and restore the appliance's finished appearance. It fits where the factory cover shields wiring and mounting points. What it does:

• Protects wiring, switches and internal parts from debris and accidental contact
• Restores the appliance's exterior finish and prevents drafts or gaps
• Stops rattling or vibration caused by damaged or loose trim
• Helps keep moisture and dust out of sensitive areas

• Disconnect power to the appliance before starting any repair.
• Remove any adjacent panels or fasteners to access the cover; retain screws and clips for reassembly.
• Align cover tabs and secure with original screws or clips; do not force or overtighten to avoid cracking.
• Replace those parts before finishing the repair.

This pulley is part of your appliance's belt-drive system. It provides a smooth, low-friction surface for the drive belt and helps keep it tracking correctly so the motor can transfer power reliably to the drum or tub.

• Guides the drive belt and rotates freely to reduce friction and wear
• Helps maintain proper belt alignment for consistent operation
• Worn pulley symptoms can include squealing/squeaking, grinding or wobble, belt fraying or coming off, and little or no drum/tub movement
• If noise or belt damage persists, inspect the belt, tensioner/idler components, and rollers/bearings

• Disconnect power and, if applicable, shut off gas before servicing
• Access the drive path and note belt routing before removal
• Relieve belt tension, remove the old pulley, and transfer any spacers/retainers as needed
• After installation, spin the pulley by hand to ensure smooth, quiet rotation; replace a worn belt at the same time

The Hose is an OEM part for Whirlpool washing machines. It is a gasket or seal located inside the machine that protects internal components from leaks or damages. The hose washer plays an important role in sealing hoses and pipes to prevent water from escaping during rotation, agitation, and drain cycles. 

Causes of a bad hose include cracks, tears, or warpage over multiple usage cycles which allows water to bypass intended drainage paths. When this occurs, it can lead to excess moisture inside the washer cabinet. 

Symptoms of a bad hose include:

• Water leaks underneath or around the washer
• Puddles or standing water inside the washer cabinet 
• Slow or ineffective draining during washing cycles

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

The Drain Hose is an OEM part for Whirlpool washers. It is responsible for carrying the wastewater out of the washer during the draining process.

A bad drain hose can be caused by wear and tear, blockages, or damage. If you notice water leaks, slow or incomplete drainage, or unusual noises during the draining cycle, it may indicate a problem with the drain hose.

Symptoms of a bad drain hose include:

• Water leaks around the hose connection points
• Slow or incomplete draining of water from the washer
• Gurgling or unusual noises during the draining process
• Visible damage or signs of wear on the hose

Replace your faulty drain hose with this genuine OEM Whirlpool part to restore your washer. 

This Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.
