Whirlpool, Kenmore & Maytag Dryer Thermal Cut-Off Kit Parts — Models & Compatibility

Your Kenmore dryer ran perfectly for 22 years, then suddenly stopped producing heat. Or maybe your Whirlpool dryer gets too hot and won't shut off. The 279816 thermal cut-off kit is one of the most common failure points in Whirlpool-manufactured dryers — whether they're branded Whirlpool, Kenmore, or Maytag. This hub covers which models use this kit, how to verify compatibility, and what makes this part fail so frequently.

Is This the Right Part for Your Model?

The 279816 thermal cut-off kit fits dozens of Whirlpool, Kenmore, and Maytag dryer models. Your model number is typically on a metal tag inside the dryer door opening or on the back panel. Models like WED4750XQ0, WED4800BQ1, NED4600YQ0, and NED4655EW0 all use this exact kit. The kit includes both the high-limit thermostat and the thermal fuse — two separate safety components that work together to prevent overheating.

About This Replacement Part

The thermal cut-off kit typically fails due to overheating, often caused by a clogged lint vent or a faulty heating element. When airflow gets restricted, the dryer heats up beyond safe limits, and the thermal fuse blows to prevent a fire. Once blown, it creates an open circuit that completely stops the dryer from heating. You'll know you need this part if your dryer runs but produces no heat, won't advance through the timer cycle, or — less commonly — gets dangerously hot and won't shut off. One single mom who'd never touched a continuity tester before successfully replaced this kit in 15-30 minutes using our videos.

Common Symptoms This Part Fixes

• No heat or not enough heat: The most common symptom — clothes tumble but stay wet
• Timer won't advance: Dryer runs continuously without progressing through cycles
• Too hot: Clothes come out scorching or with heat damage
• Doesn't shut off: Dryer continues running past the cycle end

Installation Tips from Real Repairs

Before you start, unplug the dryer — this isn't optional when working with heating elements. Label your wires before disconnecting anything; it'll save you headaches during reassembly. The kit can be rotated 180 degrees, so either side works for installation. When you first fire up the dryer after replacement, don't panic if you smell something odd for the first 5 minutes — that's just manufacturing oil burning off the new components. Test for continuity with a multimeter before installation to confirm the new parts are good.

Why This Part Fails

Thermal cut-offs don't just fail randomly. They're designed to blow when something else goes wrong. A clogged vent restricts airflow, forcing the heating element to work overtime. A failing heating element can overheat. Even something as simple as overloading the dryer drum reduces air circulation enough to trip the thermal fuse. If you replace this kit without fixing the underlying cause — especially a blocked vent — you'll be replacing it again in six months.

What You'll Need

This is one of the easier dryer repairs. You'll need basic screwdrivers, pliers, a socket set or nut drivers, and a multimeter or continuity tester to verify the old part is actually blown. Most repairs take 15-30 minutes once you've got the dryer cabinet open. The hardest part is usually accessing the heating element housing, which varies slightly between Whirlpool and Maytag models.

Compatible Model Series

This thermal cut-off kit works across multiple series of Whirlpool-manufactured dryers. The WED4700, WED4750, WED4800, and WED6200 series all use this part. On the Maytag side, you'll find it in NED4600 and NED4655 models. Kenmore dryers built by Whirlpool (typically model numbers starting with 110) also use the 279816 kit.
