Understanding the Problem
If your Whirlpool WED5620HW1 drum tumbles but the dryer does not produce heat, the cause is usually a failed heating circuit component or an airflow/venting issue that trips safety devices. Electric dryers rely on a heating element plus thermostats and a thermal fuse. When one of these parts fails or the vent is restricted, the dryer may run without generating warm air. Start by confirming that the dryer is getting full power (240V for electric dryers) and that the drum spins normally. Next, check the exhaust vent for blockages and the lint screen for lint build-up. After ruling out airflow and power issues, focus on the heating circuit: thermal fuse, heating element assembly, cycling thermostat, and high-limit thermostat are the most common failure points on this model.
Common Symptoms
Dryer runs and tumbles but produces little or no heat; clothes remain damp after a full cycle; dryer may take much longer than normal to dry; sometimes trips a circuit breaker if there's a short.
Common Causes
- Blown thermal fuse caused by overheating or restricted venting
- Open or burned heating element
- Faulty cycling thermostat or high-limit thermostat
- Restricted exhaust vent or clogged lint screen reducing airflow
- Failed dryer control or wiring issue (less common)

Helpful Repair Tip
Begin with a simple continuity check: disconnect power, remove the back panel or lower access panel, and test the thermal fuse for continuity first — it’s a single-use safety part that often fails when venting is restricted.
Frequently Asked Questions
How do I test the thermal fuse on my WED5620HW1?
Unplug the dryer and access the thermal fuse (usually on the blower housing or rear bulkhead). Remove the wires and test with a multimeter set to continuity or ohms. A good fuse shows near-zero ohms/continuity; a blown fuse shows infinite resistance (open). Replace the fuse if it’s open — don’t bypass it.
Can I replace the heating element or thermostat myself?
Yes — many owners can replace the heating element, thermal fuse, and thermostats with basic tools. Always unplug the dryer first and take photos of wiring before disconnecting. If you’re uncomfortable working with electrical components or the problem may be the control board, hire a qualified appliance technician.
