Dryer not heating properly
A dryer not heating properly tumbles but leaves clothes damp. On electric models, one tripped leg of the 240V breaker runs the motor with no heat. Clean the lint screen and the outside vent before replacing an element. Samsung HC, Samsung HE, and Whirlpool L2 are the heat codes.
First things to check
- Electric dryers: flip both legs of the 240V breaker off and on — one tripped leg causes heat failure with a running motor.
- Clean the lint screen and run without heat first to confirm the drum turns.
- Gas dryers: confirm the gas shutoff behind the unit is fully open.
- Match your symptom to the error codes and compatible parts listed below.
- Replace the faulty part or call a technician if the fix requires sealed systems or live voltage work.

FAQ
Why is my dryer not heating properly?
The drum can turn on 120V while the heater needs both legs of 240V. Reset the double breaker, then clean the vent. A blocked exhaust overheats and shuts the heat off.
Why is my dryer not heating but it still runs?
The motor can run on one leg of a 240V breaker while the heater gets no power. Flip both breaker legs off and on, then clean the vent.
Why is my dryer not heating if the element is good?
A good element still will not heat if one breaker leg is tripped or the vent is blocked and the high-limit switch opened. Reset the breaker and clear the vent before replacing the element.
Why is my dryer not heating enough?
A partly blocked vent or a half-tripped breaker leaves the dryer warm but not hot enough to dry a load. Clean the full vent run and reset both breaker legs.
Why isn't my dryer heating at all?
No heat with a turning drum is a power or heat-circuit fault. Reset the double breaker, confirm the gas valve is open on gas models, and match HC, HE, or L2.
