Whirlpool Dryer Not Heating

If your Whirlpool dryer runs but clothes come out cold and damp, the heat circuit has failed — most often a blown thermal fuse, a burned-out heating element, or a clogged vent tripping the safety cutout. Check the vent first; it's free and the most common cause.

PF

Means: Power failure — the dryer lost power mid-cycle; not itself a heat fault but can interrupt heating.

Fix: Press Start to resume. If it recurs, check the outlet and breaker (electric dryers need both 120V legs).

E1 / E2

Means: Thermistor (temperature sensor) fault — the control can't read drum temperature, so it may cut heat.

Fix: Test the thermistor for continuity; replace if open. See the full dryer code list for readings.

Why a Whirlpool dryer won't heat

  • Clogged vent / lint (check first): restricted airflow overheats the drum and trips the thermal cutoff, killing heat while the motor still runs.
  • Blown thermal fuse: a one-time safety fuse that cuts heat permanently once tripped — must be replaced, and the cause (vent) fixed.
  • Failed heating element (electric) or igniter (gas): the element burns out; gas igniters weaken and stop lighting.
  • No 240V (electric): if one leg of the circuit is dead, the drum turns on 120V but the element gets no power.

Diagnose it step by step

  1. Clean the lint filter and the full vent duct from machine to outside wall.
  2. Unplug the dryer and check the thermal fuse for continuity; replace if blown.
  3. Test the heating element (electric) or igniter/flame sensor (gas) for continuity.
  4. For electric dryers, verify both 240V legs at the outlet with a meter.
  5. Reassemble and run a timed dry to confirm heat returns.

FAQ

Why is my Whirlpool dryer running but not heating?

The heat circuit failed while the motor still works — usually a blown thermal fuse, dead heating element, or a clogged vent tripping the safety cutout. Clean the vent first.

What's the most common cause of no heat in a Whirlpool dryer?

A blown thermal fuse, almost always caused by a clogged vent restricting airflow. Fix the vent or the new fuse will blow again.

Can I run a dryer that won't heat?

It will tumble but won't dry clothes. Diagnose the heat circuit before using it — a clogged vent that killed the heat is also a fire risk.
