XPARTCO 8572717 Washer Motor Start Capacitor
The XPARTCO 8572717 is an aftermarket replacement motor start capacitor for Whirlpool-built top-load washers and washer/dryer combination units. Unlike a run capacitor that stays in the circuit continuously, this start capacitor's job is brief and intense: at the instant the motor is commanded to start, it delivers a strong momentary boost of voltage to help the motor overcome its own inertia and get up to speed quickly. Once the motor reaches running speed, a relay switches it out of the circuit, handing off to the run capacitor for continuous operation. That short, high-stress duty cycle is exactly why start capacitors are a common failure point — they work hard for a fraction of a second on every single cycle start.
Rated 189–227 MFD at 125VAC, 60Hz. The capacitor is a black cylindrical component mounted to the rear panel of the washer, held in place by a small plastic retaining clip and wrapped in a foam shield that protects it from moisture. Common failure modes include the internal dielectric breaking down from repeated startup stress, and in some cases the capacitor overheating badly enough to produce visible smoke if it fails while still energized. A failing start capacitor produces a clear symptom: the washer motor hums but won't start, or the motor fails to spin up while other functions of the washer still respond normally. It directly replaces 357021, 3949169, 661606, W10161696, W10244889, AP6013434, AH11746660, EA11746660, EAP11746660, PS11746660, AWP49120, and PD00003006.
Quick Answer
The XPARTCO 8572717 Washer Motor Start Capacitor fixes Whirlpool-built top-load washers and washer/dryer combos where the motor hums but won't start, the washer won't agitate or spin, or there's a burning smell from the motor area. Includes foam shield. 189–227 MFD, 125VAC, 60Hz. Replaces 357021, 3949169, 661606, W10161696, W10244889, AP6013434, AH11746660, EA11746660, EAP11746660, PS11746660, AWP49120, PD00003006.

Installation Notes
⚠️ Danger — Capacitors Store A Dangerous Electrical Charge Unplug the washer or shut off the house circuit breaker before beginning. A capacitor stores an electrical charge even after power has been disconnected, and that charge can deliver a serious or fatal shock. Before touching either terminal, discharge the capacitor by shorting its two terminals together using an insulated-handle screwdriver, or by using a proper capacitor discharge tool with a resistor. Never short the terminals with a bare metal tool held with your bare hand. If you are not fully comfortable performing a capacitor discharge safely, have a qualified appliance technician replace this part instead.
⚠️ Transfer The Foam Shield To The New Capacitor Wear work gloves. Remove the washer's console and then the spring clips that secure the top/body assembly to the washer frame, using a putty knife to gently release them. With the body lifted or set aside, locate the capacitor — a black cylindrical component mounted to the rear panel, held in place by a small plastic retaining clip. Using a flat-blade screwdriver, gently pop the plastic clip away from the capacitor to release it. After confirming the capacitor is fully discharged, unplug it from the appliance wiring. Remove the foam shield from the old capacitor and transfer it onto the new one before installing — this shield protects the capacitor from moisture, and skipping it leaves the new part more exposed to washer humidity. Connect the new 8572717 capacitor to the wiring, snap it back into the plastic retaining clip in the same position, and reassemble the body, spring clips, and console in reverse order. Restore power and run a test cycle to confirm the motor starts promptly on both agitate and spin. Tools needed: putty knife, flat-blade screwdriver, Phillips screwdriver, insulated-handle screwdriver or capacitor discharge tool, work gloves.
Frequently Asked Questions
My washer motor hums but won't start. Is this the right part?
Yes, this is the classic symptom of a failed start capacitor. Since this capacitor's entire job is delivering the momentary voltage boost needed to get the motor spinning from a standstill, a failure here often leaves the motor energized and humming but unable to actually overcome its own inertia and start turning.
What's the difference between a start capacitor and a run capacitor?
A start capacitor works only for a brief moment — it delivers a strong voltage boost the instant the motor is told to start, then a relay switches it out of the circuit once the motor reaches running speed. A run capacitor, by contrast, stays in the circuit continuously while the motor operates, correcting current phase for efficiency. Because the start capacitor works so hard in such a short burst on every single start, it's a more common failure point than a run capacitor on this type of motor.
Do I need to reuse the foam shield from my old capacitor?
Yes, it's worth transferring. The foam shield wraps around the capacitor to protect it from moisture inside the washer cabinet, and reusing it on the new capacitor helps the replacement hold up the same way the original was designed to. If the foam has degraded significantly, you can skip it, but it's a simple step that adds meaningful protection.
My old capacitor got hot and smoked. Is that dangerous?
Yes — a capacitor that overheats to the point of smoking has failed in a way that can pose a fire or electrical hazard, and the washer should not be used again until it's replaced. This kind of failure typically happens when a capacitor stays energized longer than it should, generating heat it isn't designed to dissipate. Replace the capacitor and, if the washer's start relay or timer seems to be holding the capacitor in the circuit too long, have that checked as well.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine Whirlpool OEM part, but is manufactured to match the electrical specifications (189–227 MFD, 125VAC, 60Hz), cylindrical form factor, and mounting configuration of the original WP8572717 start capacitor used in compatible Whirlpool, Kenmore, Maytag, KitchenAid, and related top-load washers and washer/dryer combos.
