Understanding the Problem
If your Whirlpool WED5620HWO tumbles but does not produce heat, the issue is almost always with one of the heating system components rather than the motor or drum. Electric dryers require both a working heating element and proper safety/temperature controls (thermal fuse, thermostats, and wiring) plus full 240V supply at the terminal block. Any failure in that chain will result in no heat or very low heat. Common failure points include a burned-out heating element, an open thermal fuse (a one-time safety device), a failed high-limit or cycling thermostat, or a faulty electrical connection at the terminal block or control board. Other causes such as a clogged vent or partial loss of 240V (tripped breaker or bad terminal block) can also produce long dry times or no heat, so it’s important to follow a systematic diagnosis before ordering parts.
Common Symptoms
Drum tumbles but clothes remain damp after a full cycle; drying takes much longer than normal; sometimes a faint burning smell; dryer may run but won't produce heat at all.
Common Causes
- Open or burned heating element (no continuity)
- Blown thermal fuse or failed high-limit thermostat (safety cutouts open)
- Loss of 240V or bad terminal block/connection preventing power to the element

Helpful Repair Tip
Before replacing parts, disconnect power and use a multimeter: check for 240V at the dryer terminal block, and test continuity across the thermal fuse and the heating element. An open thermal fuse or element (no continuity) pins the likely faulty part.
Frequently Asked Questions
How do I test the heating element and thermal fuse?
Unplug the dryer. Access the heating element and thermal fuse (usually on the rear or inside the rear bulkhead). Use a multimeter set to continuity or ohms: the heating element should show continuity (low ohms). The thermal fuse is a one-time safety device and should show continuity; an open reading means it’s blown and must be replaced. Also verify there is 240V at the dryer terminal block with the dryer plugged in and a second person operating the controls (take extreme caution or hire a pro).
Can I replace these parts myself, and will replacing the thermal fuse fix it?
Yes — if you are comfortable with basic appliance repairs and safety (unplugging the appliance, handling small electrical parts, and reassembling panels), you can replace the heating element or thermal fuse yourself. Note that the thermal fuse is non-resettable: if it’s blown it indicates either the element failed or the dryer was overheating (possible vent blockage). Replace the fuse and correct any airflow or element issues. If you are unsure about working with 240V or diagnosing electrical supply problems, hire a qualified technician.
