Washer Motor Run Capacitor (Whirlpool OEM)

Whirlpool Top-Load Washer Motor Run/Start Capacitor (Part # W11395618)

Restore rapid torque generation, strong agitation cycles, and full-speed spin extraction to your laundry system with this Genuine OEM Whirlpool Washer Capacitor. This factory-certified electrical energy storage cell (Part # W11395618, which officially updates and replaces older variant stock codes like W10804665, 4959033, AP6886159, and PS12722741) acts as an essential electrical booster for your washing machine’s main drive motor.

Modern high-efficiency split-phase electric motors require a massive electrical push to break static inertia and begin rotating when the wash basket is loaded down with heavy, water-saturated laundry. This capacitor functions like a temporary high-power battery. It draws standard current from your home wall line, stores it up, and then releases a timed electrical phase shift burst directly into the motor’s starting windings. This manual electrical offset creates the necessary magnetic rotation loop required for the motor to spin forward or backward.

If the capacitor loses its capacitance rating, dries out internally, or suffers a short circuit due to house power surges, it can no longer dump enough current to start the drivetrain. This triggers critical failure symptoms, including a washing machine that fills with water and drains perfectly, but simply hums or makes a rhythmic clicking sound without agitating or spinning; a drum that struggles to rotate and stops easily; or cycles that trip your home’s main electrical breaker box the moment the wash phase attempts to fire up.

Quick Info:

• Compatibility: Precision engineered for modern vertical-modular (VMW) top-loading Whirlpool, Maytag, Amana, Kenmore, Roper, Estate, and Crosley washing machines.

• Component Design: Cylindrical aluminum casing canister pre-fitted with a dual-terminal molded plastic snap-lock wire plug receptor and an integrated metal grounding mounting bracket wing.

• Fixes Common Issues: Resolves a drive motor that hums or buzzes without rotating; failure to advance into high-speed spinning; clothes coming out soaking wet; and motor starting circuit timeouts (which can drop an active “F7 E1” or motor stalling error code).

• Difficulty: Novice to Intermediate. Accessible entirely from beneath the lower chassis frame by tilting the cabinet frame back.

⚠️ Critical Safety Warning: Severe Electrical Shock Hazard!

Capacitors are designed to store high-voltage electrical energy inside internal chemical film layers. Because of this design, a capacitor can hold a dangerous, skin-burning electrical charge long after the washing machine has been completely unplugged from the wall outlet. > Never touch the bare metal terminal leads with your bare hands immediately after opening the compartment. Before unclipping the wire harness or handling the old canister, you must manually discharge the stored energy. Take a screwdriver with a fully insulated plastic handle, and hold the bare metal blade of the screwdriver across the two terminal connection tracks simultaneously for 3 to 4 seconds. You may hear a loud, sharp “pop” sound and see a tiny blue spark—this is completely normal and means the stored current has been safely neutralized.

Step-by-Step Replacement Guidelines:

1. Absolute Power Isolation: You must completely unplug the washing machine’s electrical power cord from the wall outlet to eliminate all primary voltage lines before beginning any under-chassis disassembly.

2. Access the Under-Chassis Compartment: Turn off your water utility wall faucets and disconnect the fill hoses. Wrap a strip of heavy tape tightly around the loading door lid to keep it from swinging open. Carefully tilt the empty washing machine backward at a 45-degree angle against a stable wall or lay it completely flat onto its rear panel on top of a soft moving blanket to fully expose the open floor pan area underneath.

3. Locate the Capacitor Canister: Look right next to the central drive motor assembly and plastic drive pulley shielding guard underneath the main plastic tub base. The capacitor is the silver metallic cylinder bolted straight to the metal motor support plate frame.

4. Discharge and Disconnect: Referring to the safety warning above, safely bridge the terminals with an insulated screwdriver blade to discharge the stored power. Depress the tiny locking squeeze-tab on the plastic wiring harness connector plug block and slide it straight away from the capacitor terminal socket.

5. Unbolt and Swap the Module: Use a 5/16″ nut driver or socket wrench to unthread the single hex head sheet-metal mounting screw securing the capacitor’s integrated silver bracket directly to the chassis frame plate. Slide the failed capacitor away. Position your fresh new genuine factory W11395618 capacitor in its place, tighten down the mounting bolt, snap the plastic wire harness plug firmly back into the keyed socket until it clicks, and return the washer to its upright position.
