Denys Mitchell Key Takeaways
- A blown thermal fuse is the most frequent cause of no heat in both electric WED and gas WGD Whirlpool dryers.
- The thermal fuse is a one-time safety device — once blown it must be replaced, not reset.
- Always clear lint from the exhaust duct before replacing parts; restricted airflow causes repeat failures.
- Gas dryers add igniter and gas valve coil failures to the list of possible heat sources.
- A cycling thermostat that reads out-of-range will cause the dryer to run cold even if the heating element is fine.
The Bottom Line
A Whirlpool dryer with no heat is almost always a thermal fuse, heating element, or gas igniter — all inexpensive parts that a confident DIYer can replace in under an hour.
When your whirlpool dryer not heating becomes a problem, this guide walks you through the most likely causes and how to fix them.
When your Whirlpool dryer tumbles but produces no heat, clothes come out damp no matter how long the cycle runs. This guide walks through the most common causes on electric WED and gas WGD models, starting with the easiest checks and moving toward more involved component tests.
Start Here — Airflow and Power
Before touching any parts, check two things. First, confirm the exhaust duct isn't blocked or kinked. Restricted airflow is the leading cause of thermal fuse failures — the fuse blows to prevent a fire, and the dryer stops heating. Disconnect the duct from the back of the dryer and feel for airflow at the wall cap outside. A clogged duct can cause repeat part failures if not cleared. Second, on electric WED models, verify the dryer is on a proper 240V circuit. If one leg of the circuit breaker has tripped, the dryer will tumble (running on 120V) but produce no heat.
The Thermal Fuse — First Part to Test
The thermal fuse is a one-shot safety device mounted on the exhaust duct inside the dryer cabinet. On most WED and WGD models it's located on the back panel near the heater box. Test it with a multimeter set to continuity: a blown fuse shows no continuity and must be replaced. Replacement fuses cost from $10 and the swap takes about 20 minutes. Part numbers vary by model — consult your model's service manual or search by the number printed on the fuse itself.
Heating Element (Electric) and Igniter (Gas)
On electric WED dryers, the heating element is a coiled resistance wire inside a metal housing. A break anywhere in the coil means no heat. Test for continuity — a good element reads between 8 and 15 ohms. Replacement elements for WED models cost from $30. On gas WGD models, the igniter glows orange-hot to light the gas burner. If it's cracked or burned out, the burner never lights. You can visually confirm a broken igniter by accessing the burner assembly through the front or lower panel.
Diagnostic Quick-Reference Table
| Symptom | Likely Cause | DIY Fix? | Est. Cost |
|---|---|---|---|
| Tumbles, no heat at all | Blown thermal fuse | Yes | from $10 |
| Tumbles, weak heat only | Cycling thermostat or partial element failure | Yes | from $15 |
| Gas model — igniter glows but no flame | Gas valve solenoid coils | Yes | from $25 |
| Gas model — igniter doesn't glow | Igniter broken | Yes | from $20 |
| Tripped breaker (electric) | Single leg breaker trip | Yes — reset breaker | $0 |
| Heat works then cuts out | High-limit thermostat or airflow restriction | Moderate | from $15 |
| Burning smell, no heat | Element shorted to housing | No — technician | from $150 |
Gas Valve Solenoid Coils
On WGD gas dryers, the gas valve has two or three solenoid coils that open the valve when energized. If the igniter glows briefly then goes out without the burner lighting, the solenoid coils are the likely culprit — they fail in a way that lets the igniter heat up but prevents gas flow. A solenoid coil kit for WGD models costs from $25 and replaces all coils at once, which is the recommended approach since they age together.
Thermostats — Cycling and High-Limit
Whirlpool dryers use two thermostats in the heat circuit. The cycling thermostat regulates temperature by cycling the heater on and off — a failed one stuck open causes the dryer to run cold. The high-limit thermostat is a secondary safety device; if it trips, the heater shuts off. Both are testable with a multimeter and replaceable for from $15 each. Always test both before replacing the heating element, as a failed thermostat is often misdiagnosed as element failure.
When to Stop DIY and Call a Technician
If you've replaced the thermal fuse, confirmed element or igniter continuity, and the dryer still won't heat, the fault may lie with the control board or wiring harness. These require specialized diagnostic tools and aren't cost-effective to troubleshoot without experience. A certified technician servicing WED and WGD models can run a full component test in one visit.
