Kenmore Dryer L2 Error: Low or No L2 Voltage on Heater Circuit (Electric Dryers)
The kenmore dryer l2 error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Dryer Error Code L2 Mean? L2 on a Kenmore Elite electric dryer built on the Whirlpool 110.xx platform means the control board has detected that […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. L2 indicates an electrical supply problem. Do not attempt to bypass or work around the L2 fault — running a dryer on a degraded 240 V supply can cause terminal block overheating, insulation damage, and risk of electrical fire. Resolve the power supply issue before using the dryer.
Can I reset the code?
Yes. If the cause was a tripped breaker leg, resetting the breaker restores L2 and clears the code. If the cause is a failed breaker, loose terminal, or faulty outlet connection, L2 returns on the next cycle and an electrician or technician must make the repair.
When to stop immediately?
Stop if you notice: Circuit breaker trips again within seconds of being reset, Terminal block wires show heat discoloration, melted insulation, or loose connections that cannot be tightened securely.
Symptoms You May Notice
Dryer tumbles normally but produces no heat on any cycle setting
Because the motor and control board run on L1 alone, the dryer starts, the drum tumbles, and the timer advances — but without L2, the 240 V heating element never reaches operating temperature and the exhaust air stays at room temperature.
L2 code displayed on the control panel
The control board detects the voltage imbalance on the 240 V supply and displays L2 to alert the user that the electrical supply — not the dryer itself — is the source of the no-heat condition.
Clothes are barely warm at the end of a full timed dry cycle
A full load run through a 60-minute timed dry cycle comes out with clothes at near-ambient temperature — tumbled but not heated — confirming that the heater did not operate at any point during the cycle.
Other 240 V appliances on the same panel also misbehave
Because L2 loss often stems from the house panel rather than the dryer, other 240 V loads like the range or water heater may also run weakly or partially — a clue the fault is upstream of the dryer.
Possible Causes
Tripped or failed L2 leg of the double-pole circuit breaker
One leg of the double-pole 240 V circuit breaker has tripped or internally failed while the other remains energized — allowing the dryer motor to run normally on L1 while the L2 leg that powers the heater is dead.
DIY PossibleLoose or burned wire at the dryer terminal block
The L2 wire at the dryer terminal block has worked loose or the terminal has overheated and failed, breaking the L2 supply to the heater while L1 remains intact at the terminal block.
DIY PossibleLoose or corroded L2 connection at the outlet or wall junction box
The L2 wire at the 240 V outlet receptacle or the wire junction in the wall is loose or corroded, dropping L2 voltage below the control board's detection threshold.
Requires ProfessionalSafe Checks You Can Do

1
Reset the circuit breaker at the panel
Locate the double-pole 240 V breaker for the dryer in your electrical panel. Turn it fully to the Off position (both poles together), wait 30 seconds, then turn it firmly to On. A breaker with one leg partially tripped may look like it is in the On position — always cycle it fully Off and back On to confirm a full reset. Return to the dryer, run a short cycle, and check for heat.
A double-pole breaker with one failed internal leg will reset to On but immediately drop L2 voltage again — L2 will return as soon as the dryer tries to run the heater. A breaker that trips again immediately after reset must be replaced by a licensed electrician.

Inspect the dryer terminal block for loose or burned wires
Unplug the dryer and remove the terminal block access cover at the rear lower section of the cabinet (typically two screws). Inspect all three or four terminal block connections for wires that are loose, discolored from heat, or showing melted insulation. Tighten any loose screws to the torque specified on the terminal block label (usually 15–20 in-lb). If any terminal shows heat damage, replace the terminal block before restoring power.
A loose neutral or L2 wire at the terminal block is the most common source of L2 faults that do not involve the circuit breaker. Even a wire that looks seated may have only a few strands making contact — tighten all terminals at each inspection regardless of appearance.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Breaker resets but L2 returns within one cycle — indicating a failed internal breaker pole requiring electrician replacement
- Terminal block shows heat damage and must be replaced along with the affected wire section
- Outlet voltage measured between L1 and L2 terminals is below 200 V — indicating a panel or service entry problem
