Common Symptoms & Causes

If your Whirlpool WRX735SDHZ ice dispenser motor has failed, you’ll likely notice one or more of the following signs:

Pressing the dispenser paddle produces no ice, even though the ice maker is full
The dispenser auger makes a humming or buzzing noise but fails to rotate
Ice occasionally dispenses, then stops mid-cycle without completing the delivery
The dispenser lever activates the light and water but produces zero ice movement

These issues are most commonly caused by a burned-out dispenser auger motor, worn motor brushes, or a failed motor winding resulting from years of regular use and ice load stress.

Safety First

Unplug the refrigerator from the power outlet before starting any repair — never work on a live appliance.
Shut off the water supply valve before disconnecting any water lines or hoses.
Wear work gloves when handling metal brackets, sheet metal edges, or sharp components.
Take photos with your phone before disconnecting any wiring harnesses or connectors.
Work in a well-lit area with enough floor space to lay removed panels flat.

Step-by-Step Repair Instructions

Step 1

Unplug the refrigerator before touching any components — live voltage in the dispenser circuit can cause serious injury. Open the freezer door and pull the ice bin straight forward to remove it; it slides on a track with no screws, so forcing it at an angle can crack the housing.

Step 2

Remove the 3–4 Phillips screws securing the rear bin-cavity cover to expose the auger motor and its housing. This panel is the only thing standing between you and the motor assembly, so keep screws in a magnetic dish — they’re easy to lose inside the freezer cavity.

Step 3

Unplug the motor wiring harness, then set your multimeter to Rx1 and probe the motor windings; a healthy motor reads 50–200Ω. An open reading (OL or infinite resistance) confirms winding failure and means the motor must be replaced — a marginal reading in range but with visible burn marks is also grounds for replacement.

Step 4

Order replacement part W10631812, which is the correct auger motor for this model — using a generic substitute risks mismatched torque and premature failure. When installing, slide the shaft fully through the auger coupling until you feel it positively engage, then tighten the housing cover screws in an X-pattern to distribute clamping force evenly and prevent warping the plastic housing.

Step 5

Reconnect the wiring harness until it clicks into place — a loose connector is a common cause of repeat motor failure that looks identical to a bad motor. Slide the ice bin back onto its track and confirm it seats flush before closing the freezer door.

Step 6

Plug the refrigerator back in and press the ice dispense paddle to test immediately; the motor should respond without hesitation and produce a steady, low hum. Grinding indicates the auger coupling isn’t fully engaged, while rapid clicking suggests the motor is stalling under load — either symptom means you should unplug and re-examine the shaft engagement before running the dispenser again.

When to Call a Professional

If the issue persists after completing all steps above, the problem may involve the sealed refrigerant system, a failed main control board, or wiring that requires specialized diagnostic equipment. Contact a licensed appliance technician — attempting sealed-system repairs without EPA 608 certification is illegal and unsafe.
