Whirlpool dryer not heating: check the most common cause first (see step 1 below). Whirlpool uses brand-specific components that differ from other manufacturers.
The thermal fuse is the number one culprit on Whirlpool dryers, and here's the kicker: if it blew, a clogged vent is almost certainly why. Fix the vent first or you'll be replacing that fuse again in six months. Gas Whirlpools have a different failure path, so check the igniter and valve coils. Electric Duet models need real disassembly to reach the heating element.

Whirlpool Dryer Not Heating: Causes and Fixes
OK so here's the deal with Whirlpool dryers not heating. These machines are actually pretty well-designed, but they've got one Achilles heel and that's the thermal fuse. It's a $6 part, takes maybe 20 minutes to replace, but the real question is what caused it to blow in the first place. I've diagnosed probably 50 of these in the last year alone. Most of the time it's the vent. Sometimes it's the element. Occasionally it's a tripped circuit breaker that looks fine at the panel but isn't. Worth diagnosing before you call someone.

Symptoms You May Notice
Clothes come out damp or completely soaking wet after a full normal cycle. The drum tumbled the whole time but there was zero heat.
The dryer runs, sounds totally normal, but stick your hand near the exhaust vent outside and there's no warm air at all.
Drying times have been creeping up for a few weeks before it finally quit heating completely. That's usually a vent blockage building up slowly.
Faint burnt smell, kind of electrical, when you run a cycle.
On gas models: you hear the igniter trying to cycle but the burner never lights. Sometimes there's a faint soft whomp sound like gas tried to ignite and failed.
Can you reset a Whirlpool dryer to clear the NOT-HEATING code?
Unplug the dryer completely from the wall outlet and leave it unplugged for a full 60 seconds. Some people do 30 seconds and wonder why it didn't work, so give it the full minute. Then plug back in. Important: the thermal fuse can't be reset this way. If it blew, you replace it, period. For control board glitches, the 60-second unplug clears stored codes. After reset, run a timed dry on high heat for 10 minutes and stick your hand near the exhaust to confirm heat before you call it done.

Frequently Asked Questions
How do I know if it's the thermal fuse or the heating element that's bad?
Test both with a multimeter. The thermal fuse should read near zero ohms, basically continuity. If you get nothing, it's blown. The heating element should read 8 to 12 ohms. Open circuit means it's burned out. Honestly, start with the thermal fuse because it's a $6 part and takes 15 minutes. I've diagnosed this issue probably three times this week and it was the fuse every single time. If the fuse is fine, then pull the element and test it. They fail in a pretty predictable order on Whirlpool machines.
How much does it cost to fix a Whirlpool dryer not heating?
Thermal fuse kit (part #279973) runs about $10-15 online. Heating element for an electric model is $20-50 depending on which model you have. Gas igniter is $15-30. Gas valve coil kit is $20-40. If you're paying a tech, add $100-150 in labor on top of parts, so total professional repair usually lands between $150 and $250 for the common causes. New entry-level Whirlpool dryers are $500-700 these days, so repair almost always makes financial sense if the machine is under 10 years old.
My gas Whirlpool dryer runs but won't heat. Is it the igniter?
Probably, yeah. On gas Whirlpools, the igniter is the most common heat failure after the thermal fuse. Start a cycle and watch the burner area if you can access it. The igniter should glow orange within 30-60 seconds. If it glows but no flame follows, that's your gas valve coils letting the igniter cycle but not opening the valve. If it doesn't glow at all, the igniter itself is bad. Part #279311 fits a lot of Whirlpool gas dryer models. The igniter is fragile ceramic so be careful when handling it.
Can I keep using my dryer if it stopped heating?
You can run it, it won't catch fire just because the heat is gone. But you're just tumbling wet clothes in a cold drum, which accomplishes nothing. More importantly, if the no-heat symptom came from a blocked vent that blew the thermal fuse, continuing to run it with that blocked vent still there is a genuine fire risk. So clean the vent before you fix anything else. Seriously.
Why does my Whirlpool dryer heat sometimes but not every cycle?
That's classic cycling thermostat starting to fail, or an intermittent connection at the thermal fuse wiring harness. The cycling thermostat is supposed to cycle heat on and off to regulate temperature. When it starts going bad it can cut out completely for entire cycles randomly. Check the wire connectors at the thermostat first because they corrode and loosen over time. If the connectors look fine, replace the thermostat. It's included in the thermal fuse kit (part #279973) anyway, so you basically get it for free when you replace the fuse.
How long should a Whirlpool dryer heating element last?
Usually 8-12 years with a clean vent. The vent is everything, honestly. I've seen elements fail at 3 years on machines where the vent was never cleaned, and I've seen 15-year-old elements still running fine on well-maintained machines. High heat settings every single load also accelerates wear. If you're replacing one, the OEM Whirlpool element is worth a few extra dollars over the cheap generics. The coil wire gauge is heavier and it just lasts longer.
