Code L2
medium severity
LG models: The lint filter is at the top of the door opening on most LG DLE/DLGX models. LG's FlowSense sensor measures exhaust restriction and contributes to vent alerts. LG TurboSteam models have a water inlet valve; if a water-adjacent fault appears on a vented dryer, check whether the steam line is intact.
Common causes
- One pole of the double-pole circuit breaker tripped without the other
- Loose wire at the terminal block or breaker
Step-by-step fix
- Reset both poles of the double-pole breaker.
- If heat still fails, have an electrician check the terminal block wiring.
Tools you may need
None (breaker reset); multimeter (if testing voltage)
Prevention
- Have dryer wiring inspected if you experience repeated L2 codes without a clear power event.
When to stop DIY
Call an electrician for all 240V wiring work beyond a breaker reset.
