How to Extend Your Whirlpool Dryer Push-to-Start Switch Life — W10117655 Maintenance Guide
Always unplug the dryer before accessing the push-to-start switch. Work behind the control panel involves exposed electrical connections that can cause shock if power is connected.

Here's a reality check: the average push-to-start switch on a Whirlpool dryer lasts about 7–10 years with normal use. That's roughly 3,600 cycles if you're doing laundry every day. But I've seen these switches fail in under 3 years when people slam the button, and I've also seen them last 15+ years when treated properly. The W10117655 switch in models like the WED5000DW2 and WGD4915EW2 fails the same way every time — wear from repeated use causes internal contact degradation.
How Long Should It Last?
Under normal conditions, you're looking at 7–10 years. That's about one push per day, gentle pressure, no kids repeatedly jabbing it for fun. The switch mechanism inside is basically a spring-loaded contact assembly — every push compresses the spring, and every release lets it snap back. Metal fatigue is inevitable, but how fast it happens depends entirely on how you use it.
What kills these switches early:
- Heavy-handed pushing. Slamming the button wears the internal spring faster.
- Holding it down too long. The switch is designed for a quick push, not a 3-second hold.
- Moisture exposure. If your laundry room is humid or you've got a vent leak, moisture can corrode the contacts inside.
- Multiple restarts. Stopping and restarting the dryer repeatedly in one session puts extra cycles on the switch.
Signs It's Wearing Out
The W10117655 doesn't fail suddenly — it gives you warnings. Here's what to watch for:
Dryer Won't Start When You Push the Button
This is the classic first symptom. You push, nothing happens. Push again, it starts. The internal contacts are oxidizing or the spring tension is weakening. One user told me: "Some times dryer stayed on after pushing switch but had almost impossible to start recently." That intermittent behavior is your cue that the switch is on its way out.
Dryer Stops Running When the Button Is Released
If your dryer won't stay running after you let go of the start button, the switch isn't latching properly. The mechanism inside should hold the circuit closed once you release it — if it's not doing that, the plastic retainer or spring has worn down. I've diagnosed this dozens of times on models like the WGD4985EW0 and WED4995EW1.
You Have to Push Harder Each Time
When you notice you're applying more force to get the dryer to respond, that's spring fatigue. The switch should require consistent, light pressure throughout its life. If it's getting stiffer or mushier, replacement is coming soon.
When to Replace vs Maintain
Let's be honest — this isn't a part you can really "maintain" in the traditional sense. There's no lubrication point, no adjustment screw. It's a sealed switch assembly. But you can extend its life significantly:
Maintain it by:
- Teaching everyone in the house to push gently — one firm press, not multiple jabs
- Keeping the laundry room humidity below 60% to prevent corrosion
- Not using the dryer as a timer — run full cycles instead of stopping and restarting
- Checking that the knob isn't loose (tighten if it's wobbling, which stresses the switch)
Replace it when:
- You need multiple attempts to start the dryer more than once a week
- The dryer stops when you release the button (it's already failed at that point)
- The button feels crunchy or sticky instead of smooth
The good news? Replacement takes 15–30 minutes and costs $52.99 for the W10117655. One customer saved his wife "$500 for a new dryer" by swapping it himself in 5 minutes. You just need a screwdriver and basic confidence.
Frequently Asked Questions
Can I test the switch before replacing it?
Yes. Unplug the dryer, remove the access panel behind the control panel (6 screws), and use a multimeter to test continuity across the switch terminals when you press the button. If there's no continuity when pressed, the switch is dead. If continuity is intermittent, it's failing. One repair tech noted: "Checked voltages on switch and all seemed to be correct. Ordered switch and installed. Operated as expected after installation." Sometimes voltage tests fine but the mechanical action is compromised.
Will a failing switch damage other dryer components?
No. A bad push-to-start switch is electrically isolated — it won't send voltage spikes or damage the control board. The worst that happens is you can't start the dryer. It's a simple open/close contact switch, not a complex electronic component.
Do I need to replace the knob too?
Usually not. The knob (the plastic part you actually push) is separate from the switch assembly. Pull it off before removing the switch — if it's cracked or damaged, replace it, but most of the time the knob is fine and the internal switch mechanism is what's worn out. The W10117655 is just the switch assembly, and your existing knob will fit on it.
