GE Washer & Dryer Control Knob Parts — Models & Compatibility

Your GE washer won't start, but the power's on. You turn the timer knob and nothing happens — or worse, it just spins freely without engaging. The control knob on GE, Hotpoint, and RCA washers and dryers is the interface between you and the timer mechanism, and when it fails or strips, your machine becomes useless. This hub covers the WE01X20378 control knob and clip replacement, compatible with dozens of GE laundry models across multiple series.

Is This the Right Part for Your Model?

The WE01X20378 fits a wide range of GE top-load washers and dryers, including GTDP, GTDX, GTWP, DWSR, DJXR, WVSR, WLSR, and WBSR series. Your model number is usually located on a label inside the door opening or on the back panel near the power cord. It'll look something like GTDP180ED0WW or WVSR1060G7WW. Cross-reference your full model number with the compatibility list below — the first few letters indicate the series, but you need the exact match to ensure the knob shaft and clip design are correct.

About This Replacement Part

The WE01X20378 isn't just a knob — it includes the retaining clip that secures it to the timer shaft. When users report "Won't Start" or "Timer Not Working" symptoms, it's often because the knob has stripped internally or the clip has broken, preventing proper engagement with the timer mechanism. The knob shaft has a D-shaped profile that must mate precisely with the timer post. This replacement supersedes older part numbers WH01X10460, WE01X20432, and WH01X10307, meaning GE consolidated multiple knob designs into this universal version. If your existing knob spins without resistance or feels loose even when pushed on, you need this part. It's a simple friction-fit installation — no tools required, just pull off the old knob and press the new one firmly onto the timer shaft until the clip seats.

Common Issues Solved

This part directly addresses three specific failure scenarios. First: the machine won't start when you turn the dial because the knob isn't engaging the timer shaft. Second: the timer advances erratically or doesn't advance at all because the knob slips during the cycle. Third: the knob falls off completely, leaving you with a bare metal shaft you can't grip. All three stem from worn knob teeth or a broken retaining clip. Replacing both components together — which this part does — restores full timer control. You'll know you've installed it correctly when you feel positive detents as you rotate through cycle positions and hear the timer click into each setting.

Compatible Model Series

This control knob fits across GE's residential laundry lineup from roughly 2005-2015, including both washer and dryer models. The GTDP and GTDX series are gas and electric dryers, the GTWP series are top-load washers, and the DWSR, DJXR, WVSR, and WLSR prefixes cover various washer configurations. The compatibility spans hundreds of individual model numbers, but they all share the same timer shaft design. If you've got a GE or Hotpoint washer or dryer from this era with a broken or loose control knob, this is your part.
