GE Dryer Timer Knob Parts — Models & Compatibility

Your GE dryer's timer knob is that white plastic dial you twist every single day — and when it cracks, strips out, or falls off completely, you're stuck guessing where you are in the cycle or just letting it run until you remember to check it. This hub covers the WE01X20374 timer knob replacement that works across GE's GTDP electric dryer series, including both 180, 200, 250, and 280 models.

Is This the Right Part for Your Model?

Check your model number on the label inside the dryer door opening — it'll start with GTDP followed by three digits and a letter-number combination (like GTDP180ED3WW or GTDP250GM2WW). This white timer knob fits the entire GTDP electric dryer family manufactured from the mid-2000s through early 2010s. The knob press-fits onto a D-shaped shaft on the timer assembly — you don't need the timer itself, just this outer control knob.

About This Replacement Part

The WE01X20374 is a direct factory replacement for the original timer knob used on GE and Hotpoint electric dryers. It's molded from durable white ABS plastic with internal ridges that grip the timer shaft securely. This part supersedes older numbers like WE1M856, WE1M589, and AP5805160 — they're all the same current production knob. The most common failure happens when the internal D-shaped socket cracks from years of twisting or someone forcing it past the stop position, which causes the knob to spin freely without actually turning the timer mechanism underneath.

Installation Overview

Replacing this knob takes about 30 seconds. Pull the old knob straight off the timer shaft — it might be stuck if the plastic's degraded, so wiggle it side to side while pulling. Clean any plastic debris or residue off the D-shaped metal shaft with a paper towel. Line up the new knob's internal D-socket with the shaft shape and press firmly until it seats flush against the control panel. Give it a test rotation through the cycle settings to verify it's engaging properly.

Why This Part Fails

Timer knobs crack for three main reasons: UV exposure if your dryer's near a window causes the plastic to become brittle, repeated overtightening when someone cranks it past the cycle stop point stresses the internal socket, and simple age — after 10-15 years of daily twisting, even good plastic eventually fatigues. You'll know it's failed when the knob spins without moving the timer dial underneath, when visible cracks appear around the center hole, or when the knob pulls off easier than it should because the internal grip teeth have worn smooth.
