Kenmore Dryer Error Code L2

The L2 error code on a Kenmore dryer indicates that the control board has detected low or absent voltage on the L2 leg of the 240-volt supply circuit. Electric dryers require two 120-volt legs (L1 and L2) that combine to deliver 240 volts for the heating element, while the drum motor and controls run on 120 volts from a single leg. When the control detects less than 50 volts on the L2 leg, it triggers this fault to alert the user that the dryer cannot operate safely or effectively. The machine may still power on partially since the L1 leg may be intact, but heating will be absent or severely reduced.

The most common cause of this condition is a blown household fuse or a tripped circuit breaker on one leg of the dedicated 240-volt dryer circuit. Unlike standard household circuits, a 240-volt breaker is a double-pole unit, and it is possible for only one pole to trip or one fuse to blow, cutting power to L2 while leaving L1 energized. This is why the dryer may appear to have partial power but produces no heat. A faulty or improperly installed power cord is another frequent culprit, particularly if the terminal block connections are loose or the cord wiring was routed incorrectly during installation.

Diagnosing this code requires checking the breaker panel first, then verifying voltage at the outlet with a multimeter. A properly functioning 240-volt dryer outlet should measure approximately 240 volts between the two hot terminals and approximately 120 volts from each hot terminal to neutral. If outlet voltage is confirmed correct, the power cord, terminal block connections, and internal wiring to the control board should be inspected for damage or loose connections.
