Understanding the Problem
If your Whirlpool electric dryer tumbles but clothes stay damp or it produces no heat at all, the cause is usually a failed heating circuit component or a loss of full 240V supply. Common components that fail include the thermal fuse (which blows if the dryer overheats), the heating element assembly (which can break or short), cycling and high-limit thermostats, and sometimes the timer or control board. A clogged vent or lint screen can also cause overheating that trips safety devices and reduces heat transfer to the clothes. Before replacing parts, always verify power and airflow first. Electric dryers require two 120V legs (about 240V across the two outer terminals) to create heat; if one leg is missing the dryer may run but won't heat. After confirming proper power, check the thermal fuse and heating element for continuity and inspect the venting for blockages—these checks will point you to the right replacement part and prevent unnecessary purchases.
Common Symptoms
Dryer tumbles but clothes remain damp or take extremely long to dry; no heat at all; dryer runs but trips thermal safety; breaker trips or a single heating element coil visibly broken; poor airflow or excessive lint in the vent.
Common Causes
- Blown thermal fuse (safety device that cuts heat when overheating occurs)
- Open heating element or broken heating coil
- Loss of one hot leg/240V power to the dryer (trips or bad cord/outlet)
- Faulty cycling thermostat or high-limit thermostat/thermal cutoff
- Severely restricted venting or clogged lint screen causing overheating and fuse failure

Helpful Repair Tip
First check for ~240V at the dryer terminal block (with the dryer plugged in) and then test the thermal fuse and heating element for continuity with a multimeter. If one hot leg is missing you don’t need new parts—the outlet or house breaker is the problem.
Frequently Asked Questions
My Whirlpool dryer runs but doesn't heat — what's the first thing I should check?
First verify the dryer is getting full 240V: unplug the dryer, then plug back in and measure voltage at the terminal block (or measure between the two outer terminals with the dryer plugged in) — you should see about 240V. If you only have ~120V between each outer terminal and neutral, one hot leg is missing (bad outlet, cord, or house breaker). If power is OK, check the thermal fuse for continuity and inspect the heating element for visible breaks or an open circuit with a multimeter.
How do I test the thermal fuse and heating element safely?
Unplug the dryer and move it away from the wall. Access the thermal fuse (usually on the blower housing) and the heating element (rear panel or inside cabinet depending on model). Use a multimeter set to continuity or ohms: a good thermal fuse and heating element will show continuity (low resistance). An open (infinite) reading means the part is blown/failed and should be replaced. Also check for obvious signs of damage to the element and make sure lint and vents are clear before reassembly. If you’re not comfortable with live-voltage tests or disassembly, hire a qualified technician.
