Understanding the Problem
If your Whirlpool DV306LEW/XAA dryer tumbles normally but fails to produce heat, the issue is usually with one of the dryer’s safety/heat components or the heating element itself. Electric dryers rely on a heating element, a thermal (safety) fuse, and thermostats/cutoffs to allow and regulate current to the heater. Any one of these failing will stop the heater while leaving the drum motor and timer/control functioning. When diagnosing, start with the simplest, most common failure: the thermal fuse. It’s a one-time safety device that opens if the dryer overheats (often due to restricted venting). Other common causes are an open heating element, a faulty cycling thermostat or high-limit thermostat, or a problem with the line voltage feeding the dryer. Proper testing with a multimeter and visual inspection of lint buildup/venting will quickly narrow down the culprit.
Common Symptoms
Drum tumbles and controls operate normally, but clothes stay cool or damp; dryer may take much longer to dry or produce only slightly warm air. No error codes in many cases.
Common Causes
- Blown thermal (safety) fuse caused by an overtemperature event or restricted venting
- Open or shorted heating element (broken coil or failed element assembly)
- Faulty thermostats (cycling thermostat or high-limit thermostat) or interrupted line voltage

Helpful Repair Tip
Before replacing parts, confirm the thermal fuse and heating element with a multimeter for continuity; also check that the dryer is receiving proper 240V (two hot legs) at the terminal block — lack of full voltage will prevent heating even if parts test good.
Frequently Asked Questions
How do I test the thermal fuse on my DV306LEW/XAA?
Unplug the dryer, access the fuse (usually on the blower housing or near the heating element), remove the wires, and test for continuity with a multimeter. A good fuse shows close to 0 ohms; an open (OL) reading means the fuse is blown and must be replaced. Also inspect the vent and lint screen — restricted airflow is a common cause of blown thermal fuses.
Can a dryer still tumble if the heating element is bad?
Yes. The motor that tumbles the drum is separate from the heating circuit. If the motor and controls are fine but the heater or safety devices are open, the dryer will tumble but not produce heat. Always test the heating element and thermal cutoffs when diagnosing no-heat conditions.
