FAQ

This worm gear is used in certain stand mixers made by KitchenAid, Whirlpool, and Kenmore. Compatibility depends on the exact mixer model, so the safest match is to verify your model number and confirm it uses part W10112253 or one of its cross-reference numbers before ordering.
This part cross-references to W10112253, WPW10112253, 4161531, 4162897, 4169830, AP4295669, PS11748374, and WPW10112253VP.
A worn or stripped worm gear often causes the mixer motor to run while the planetary or beater stops turning, slips under load, makes grinding noises, or loses mixing power on thicker doughs and batters. In many stand mixers, this gear is designed to wear first to help protect the motor and transmission from more serious damage.
This is typically a moderate repair for someone comfortable opening a stand mixer gearbox. The job usually takes about 45 to 90 minutes depending on the mixer model and condition. Common tools include screwdrivers, a punch or drift pin, snap-ring pliers if applicable, pliers, a small hammer, and food-grade grease for reassembly.
Before installation, unplug the mixer and inspect the transmission housing for metal or nylon gear debris. Check the mating gears, bearings, gearcase gasket or seals, retaining pins, and grease condition. If the old grease is contaminated with gear fragments, it is a good idea to clean out the gearbox and apply fresh food-grade grease during reassembly.
Worm gears commonly fail from repeated heavy loads, stiff bread dough, mixer jams, lack of lubrication, or age-related wear. In many stand mixers, the worm gear is intentionally a sacrificial gear, meaning it may strip during overload to reduce the chance of damage to more expensive internal drive components.
