Whirlpool Dryer Error Code L2

The L2 code means the Central Control Unit detected that the L2 power leg is supplying less than 50 volts. A dryer needs two 120V legs to total 240V for normal operation, particularly for heating. This error points to a power supply problem, not a failed dryer component, and the source is usually the breaker, power cord, outlet, or home wiring.

Start by checking your home's electrical panel for a tripped breaker on the dryer's double-pole circuit. Reset it if tripped, then check whether the error clears. If the breaker is fine, inspect the power cord for damaged wires and the terminal block on the back of the dryer for burnt connections. Whirlpool's recommended procedure follows the F4E4 fault code diagnostics, which walks through testing line voltage at multiple points. If the fault traces back to household wiring or the panel, a licensed electrician should handle the repair.

A breaker can appear set in the ON position but still be internally tripped or failing, delivering voltage on only one leg. Test the breaker by fully switching it OFF and then back ON. If the L2 error persists, use a multimeter to measure voltage at the dryer outlet. You should read approximately 240V across the two hot slots and approximately 120V from each hot slot to the neutral. A reading below that on the L2 slot confirms a wiring or breaker problem that needs electrical service.

No. Running the dryer with an L2 error is not advisable. With insufficient voltage on the L2 leg, the heating element will not operate correctly and the motor may be stressed running on reduced power. More critically, the underlying cause could involve arcing at a connection point, which is a fire hazard. Resolve the power supply issue before operating the dryer.

Cost varies depending on the cause. Resetting a tripped breaker costs nothing. Replacing a dryer power cord typically costs $20 to $50 in parts and is a DIY-friendly repair. A new dryer outlet or terminal block repair runs $50 to $150 with an electrician. If the branch circuit wiring needs repair, electrician labor and materials can range from $150 to $400 or more depending on the scope of the problem.
