How to Replace W10006355 Washer Shift Actuator on Whirlpool Top-Load Washers — Step-by-Step

Your Whirlpool washer won't agitate. The drum spins during the spin cycle, but when it's time to wash, nothing happens. You hear the motor running, maybe even a clicking sound, but the agitator just sits there. If you're dealing with a WTW4800BQ0, NTW4600YQ0, or similar Whirlpool top-loader, you're probably looking at a failed shift actuator — the W10006355.

This actuator controls the mechanical shift between agitate and spin modes. When it fails, your washer gets stuck in one mode or won't start at all. The good news? It's accessible from underneath the washer, and you don't need to tear apart the entire machine.

What You Need Before Starting

This repair requires getting under your washer, so you'll need a clear workspace and the right tools:

• 1/4-inch nut driver or socket set
• Flathead screwdriver
• Towels (for any residual water)
• Work gloves
• Flashlight or work light

Estimated Repair Time: 45-60 minutes

Difficulty Level: Moderate — You'll need to tip the washer, but the actual part swap is straightforward.

Safety First

Warning: Unplug the washer completely before starting. Top-load washers are heavy — get someone to help you tip it. Never work on a washer that's still connected to power. If you're not comfortable tipping the machine or working underneath it, call a pro. Water may still be present in hoses and the pump area, so keep towels handy.

Step 1: Access the Bottom of the Washer

Unplug the washer and turn off the water supply. Pull the machine away from the wall — you need about three feet of clearance. With a helper, carefully tip the washer forward so it rests on its front panel. Most Whirlpool top-loaders are designed for this service position. You'll now see the entire underside of the machine. The shift actuator is the white cylindrical component mounted near the transmission, usually on the right side.

Step 2: Disconnect the Wiring Harness

Locate the wire connector attached to the actuator. Press the locking tab and pull the connector straight out — don't yank on the wires themselves. If the connector feels stuck, wiggle it gently while pressing the release tab. Take a photo with your phone before disconnecting anything; it'll help during reassembly.

Step 3: Remove the Failed Actuator

The W10006355 is held in place by two or three 1/4-inch hex-head bolts. Use your nut driver to remove these mounting bolts completely. Once the bolts are out, the actuator should pull straight out from the transmission housing. You might need to wiggle it slightly — it's seated with an O-ring that can stick. If you see any grime or metal shavings around the mounting area, wipe them clean with a rag before installing the new part.

Step 4: Install the New W10006355 Actuator

Line up the new actuator with the mounting holes. The shaft on the actuator needs to engage with the shift mechanism inside the transmission — push it in firmly until it seats completely. Don't force it; if it won't go in smoothly, you might have the orientation wrong. Once seated, thread in the mounting bolts by hand first, then tighten them snugly with your nut driver. Don't overtighten — you're threading into plastic or soft metal.

Step 5: Reconnect and Test

Plug the wire harness back onto the new actuator until you hear it click. Give it a gentle tug to confirm it's locked in place. With your helper, carefully lower the washer back to its upright position. Reconnect the power and water supply. Run a small test load on a normal cycle. Listen during the first few minutes — you should hear the actuator clicking as it shifts between agitate and spin. If the washer agitates properly and advances through all cycles, you're done.

Testing After Installation

Start with an empty washer and run it through a complete cycle. Watch for these signs that everything's working: the agitator moves back and forth during the wash phase, the drum spins freely during spin cycle, water drains completely, and the cycle advances automatically. If you're still seeing issues like slow spinning or cycles not advancing, double-check that the wire connector is fully seated and the actuator is pushed in completely.

Frequently Asked Questions

Will this actuator work on my Maytag or Kenmore washer?

Yes, if your model number is listed in the compatibility data. The W10006355 replaces WPW10006355, AP6014711, and PS11747977. It fits Whirlpool, Maytag, Kenmore, and Amana top-loaders that use this style transmission. Check your model number against models like 7MWTW1500AQ0, ATW4675YQ0, or 1CWTW4740YQ0 to confirm.

How do I know if the actuator is bad or if it's something else?

A failed shift actuator usually shows up as a washer that won't agitate, won't spin, or won't drain properly because it can't shift modes. You might hear clicking or buzzing but no mechanical action. If your washer won't start at all and makes no sound, check the lid switch first. If it spins but never agitates, the actuator is the likely culprit.

Can I replace this without tipping the washer forward?

Not really. The shift actuator mounts to the bottom of the transmission, which is only accessible from underneath. Some techs use appliance dollies or ramps, but tipping forward is the standard method. Make sure you have help — these machines weigh 150+ pounds and are top-heavy when tipped.
