GE & Hotpoint Dryer Timer Knob Parts — Models & Compatibility

If you're staring at a missing or cracked timer knob on your GE or Hotpoint dryer, you're not alone. The WE01X10160 timer knob fits dozens of models across the WSM2700 and WSM2780 series, plus several MEX731 commercial units. This is a direct replacement for AP3207448, PS755794, and WE01X10069 — same part, different supplier codes.

Is This the Right Part for Your Model?

The fastest way to confirm compatibility is checking your dryer's model number plate. On most GE dryers, you'll find it inside the door frame or on the back panel near the power cord. Match your full model number (including any letters after the dash) against the list below. The WE01X10160 knob works across multiple series because GE used the same timer shaft design from the early 2000s through mid-2010s production runs.

About This Replacement Part

The timer knob is what you physically turn to select drying cycles — it's the interface between you and the mechanical timer mechanism behind the control panel. While it seems simple, a broken knob means you can't operate your dryer at all. Most failures happen from years of twisting force combined with heat exposure, which makes the plastic brittle. You'll know you need this part when the knob spins freely without engaging the timer shaft, has visible cracks radiating from the center, or has broken off completely. This replacement includes the knob body and the D-shaped insert that grips the timer shaft — no separate components to track down.

Compatible GE & Hotpoint Models

This timer knob fits 20+ models in the WSM2700 and WSM2780 families, plus select commercial MEX731 units. If your model starts with WSM27 or MEX731, there's a strong chance this is your part.

Installation Overview

Replacing a timer knob is one of the simplest dryer repairs you can do. Pull the old knob straight off the timer shaft (if it's still attached), then push the new WE01X10160 knob onto the D-shaped shaft until it seats flush against the control panel. The D-shape prevents it from spinning freely — make sure it's oriented correctly before pressing it on. No tools required, takes about 30 seconds. The knob should turn smoothly through all cycle positions with a satisfying click at each stop.

Why This Part Fails

Timer knobs fail from mechanical stress, not electrical issues. Every time you turn the knob, you're applying torque to a plastic part that's also exposed to years of dryer heat cycling. The plastic becomes less flexible over time, and eventually cracks form around the center hub where the shaft connects. Heavy-handed turning accelerates this — especially if someone forces the knob past its natural stopping points. Once cracks start, they spread quickly. Commercial models like the MEX731 series tend to wear out faster simply because they see more daily use cycles.

Part Number Cross-Reference

The WE01X10160 replaces several older part numbers from GE's supply chain updates. If you're cross-referencing from an old repair receipt or parts diagram, these numbers all lead to the same current part: AP3207448, PS755794, WE01X10069, and WE1X10160 (the version without the zero). Appliance parts vendors sometimes list these separately, but they're identical knobs. GE consolidated the part numbers around 2015, so anything you order today will ship as WE01X10160.
