OEM vs Aftermarket Washer Timer Knob for Whirlpool & Kenmore: Honest Comparison (3362624)

Your Kenmore 110.82891120 won't start because the timer knob spun freely this morning—the internal teeth finally gave out after years of turning. Now you're staring at two prices: $40.99 for an aftermarket replacement or $65–$85 for the OEM Whirlpool version. Which one actually makes sense for a plastic knob that gets twisted twice per load?

Quick Answer

For this timer knob, aftermarket wins on value. You're getting identical ABS plastic construction and the same internal teeth configuration for nearly half the price. The OEM markup comes from branding, not better materials—both knobs typically last 8–12 years with normal use.

Side-by-Side Comparison

When OEM Makes Sense

Honestly? There aren't many scenarios where paying double for the OEM knob is justified. The only time I'd recommend it is if you're repairing a washer under an existing extended warranty that specifically requires OEM parts—some protection plans will deny claims if they spot aftermarket components during a service call.

If you're selling the washer within the next few months and the buyer is weirdly particular about "all original parts," the OEM packaging might add $20 to your resale value. But that's a narrow case.

The other situation: you're already ordering multiple OEM parts from a Whirlpool service center and want everything on one invoice for a rental property expense report. The convenience might be worth the premium if you're buying in bulk.

When Aftermarket Wins

For this specific part, aftermarket is the smarter choice in nearly every scenario. You're looking at a simple knob—no electronics, no sensors, just molded plastic with internal teeth that engage the timer shaft. The failure mode is always the same: the teeth strip out or crack, preventing the knob from catching.

The aftermarket version uses the exact same tooth configuration (D-shaped shaft with 12 internal ridges) and identical chrome-plated ABS plastic. We've installed hundreds of these on Kenmore 110-series washers—models like the 110.828918100, 110.92093320, and 110.92570200—and the fit is perfect every time.

Here's the kicker: Heima's warranty is actually longer than OEM. You get a full year versus Whirlpool's standard 90-day parts warranty. If this knob fails within 12 months (which is rare), you're covered. The OEM knob offers no such protection after three months.

Installation takes about 45 seconds—you pull the old knob straight off (it's friction-fit, no screws) and push the new one onto the timer shaft until it clicks. If your washer "Will Not Start" because the knob spins freely without advancing the timer, this replacement solves it immediately. No tools, no disassembly panel removal, nothing.

Our Verdict

Go aftermarket. The 3362624 timer knob is a commodity part where brand markup adds zero functional value. You're saving $25–$45, getting better warranty coverage, and receiving identical performance. If this were a control board or a motor capacitor, we'd have a more nuanced discussion—but for a plastic knob? Keep your money and buy the aftermarket version with confidence.

The Real Cost Breakdown

Let's do the math over a typical washer lifespan. If you replace this knob once every 10 years (average usage pattern) across a washer's 20-year life, you'll need it twice. With OEM, that's $130–$170 total. With aftermarket, it's $82. You're saving $48–$88 over time with zero difference in reliability.

That savings pays for a full set of washer suspension springs or a new drain pump down the road when you actually need them.

Compatibility Note

This knob fits over 40 Kenmore 110-series models and Whirlpool direct-drive washers manufactured between 1998 and 2014. Double-check your model number (it's on the rim inside the washer lid), but if you have a 110.82891120, 110.816611, 110.828918110, or similar Kenmore model, this is your part. The D-shaft design is universal across that entire generation.

Frequently Asked Questions

Will the aftermarket knob match my washer's color exactly?

The chrome finish matches OEM spec, but white and almond washers have slight color variations even between OEM production runs. The knob will function perfectly regardless—nobody's inspecting your timer knob for perfect color match unless you're entering your laundry room in a home show.

Can I use this on a dryer timer?

No. Dryer timer shafts are typically smaller diameter and use different tooth patterns. This is specifically for washer timers on the models listed. If you force it onto a dryer, it won't stay secured and you'll strip the shaft.

What if the timer shaft itself is damaged?

If the metal timer shaft is rounded off or broken, a new knob won't help—you'll need to replace the entire timer assembly (part WP3952371 for most Kenmore 110 models). But that's rare. Usually the knob fails first because plastic fatigues faster than metal. Inspect the shaft before ordering; if you see clean D-shaped edges, you just need the knob.
