How to Replace WE1M964 Dryer Timer Knob on GE Hotpoint Dryer — Step-by-Step

You twist the timer knob to start your dryer, but nothing happens. Or maybe the knob just spins freely without engaging the timer mechanism underneath. Before you call a repair tech for what's essentially a $14.99 fix, let's walk through replacing this knob yourself.

The WE1M964 timer knob is one of the simplest parts to replace on your GE or Hotpoint dryer. This knob fits models like the GTDL310EM0WS, GTDP300EM1WS, GTDP350EM2WS, and dozens of other GE dryer models. When the internal teeth strip out or the plastic cracks, the knob won't grip the timer shaft anymore.

What You Need Before Starting

Tools required: None. This is a hand-only repair.

Time needed: 2-3 minutes

Difficulty: EASY — Perfect first repair if you've never fixed an appliance before

Safety First

Technically you don't need to unplug the dryer for this repair since you're only touching the external knob. However, if you want to be extra cautious, go ahead and unplug it. The repair takes less time than walking to your breaker box.

Step 1: Remove the Old Timer Knob

Grab the broken knob firmly and pull straight out. Don't twist — just pull. The knob should slide off the D-shaped metal shaft that sticks out from the timer. If it's stuck, wiggle it gently side to side while pulling. Some knobs have been on there for 10+ years and might need a bit of persuasion.

Step 2: Inspect the Timer Shaft

Look at the metal shaft you just exposed. It should be a flat D-shape — one side flat, three sides rounded. Wipe off any dust or lint with your finger. If the shaft itself is damaged or broken, you'll need the actual timer assembly (different part, different repair). But if the shaft looks fine, you're good to continue.

Step 3: Align the New WE1M964 Knob

Take your new WE1M964 knob and look inside the back. You'll see a D-shaped hole that matches the shaft. Line up the flat side of the hole with the flat side of the shaft. This is the only way it'll fit — the D-shape prevents you from putting it on wrong.

Step 4: Press the Knob Into Place

Push the knob straight onto the shaft until it seats completely. You'll feel it click or bottom out when it's fully on. Give it a gentle tug to make sure it's secure. The friction fit should hold it firmly in place.

Step 5: Test the Timer Function

Turn the knob through its complete cycle. It should rotate smoothly with slight resistance from the timer mechanism. Each click you hear is the timer advancing through its positions. Set it to a timed dry cycle and make sure the dryer starts when you expect it to.

Testing After Installation

Run a short 10-minute timed dry cycle with nothing in the drum. The timer should advance during the cycle, and the dryer should shut off automatically when the cycle completes. If the knob feels loose or spins without engaging the timer, remove it and reinstall — you probably didn't push it on completely the first time.

Frequently Asked Questions

Why does my timer knob keep breaking?

If you've replaced this knob multiple times, you're probably turning it too hard. The timer knob should rotate with light finger pressure. If you're gripping and forcing it, you're stripping the internal teeth. Also, pulling the knob outward while turning it (like opening a safe) puts stress on the plastic and causes premature failure.

Will this WE1M964 knob fit my specific GE dryer model?

This knob fits over 50 GE and Hotpoint dryer models including the GTDL310, GTDP300, GTDP301, and GTDP350 series. Check the compatible models list on the product page. If your model number starts with GTD, there's a 95% chance this is your knob. It replaces the older part numbers AP4980845, PS3487132, and 1811122.

Can I just glue the old knob back on instead of buying a new one?

Don't. Seriously, don't. The knob needs to grip the D-shaped shaft precisely to transfer your turning motion to the timer mechanism. Glue adds thickness that prevents proper engagement, and it'll fail again — probably mid-cycle when you need your dryer most. At $14.99, just replace it properly and be done with it.
