FAQ

This worm gear fits a wide range of KitchenAid, Whirlpool, and Kenmore stand mixers. It is designed for both tilt-head and bowl-lift style models; please verify your specific model number and existing part number to ensure compatibility before ordering.
This part replaces W10112253 and WPW10112253. It also cross-references with part numbers 4161531, 4162897, 4169830, AP4295669, PS11748374, and WPW10112253VP.
A failed worm gear often causes the motor to run while the beater stops or turns weakly under load. Other common symptoms include grinding noises, intermittent mixing action, or a mixer that works when empty but stalls when processing thick dough or batter.
The worm gear acts as a sacrificial component designed to protect the motor and drivetrain from damage during an overload. Repeated heavy dough mixing, sudden jams, or long-term wear can strip the gear teeth. Additionally, old or contaminated grease inside the gear case can accelerate wear.
This is a moderate repair that requires opening the mixer housing and gear case. You will need basic hand tools, including screwdrivers, a punch or drift for pins, snap-ring pliers for certain models, and cleaning supplies for the old grease. For those familiar with appliance repairs, the process typically takes 30 to 90 minutes, depending on the specific mixer model and the amount of cleaning required.
Before installation, unplug the mixer and inspect the transmission area for broken gear teeth, worn follower gears, damaged bearings, and contaminated or dried grease. It is also important to determine if the previous failure was caused by an overload or jam, as replacing the gear alone may not resolve the issue if other drivetrain components are binding.
Yes, this package contains 4 worm gears, which is ideal for servicing multiple mixers or maintaining a supply of spare parts.
