What should I do if the 'L2' diagnostic code appears on the display?

The dryer will continue to run when this indicator is lit. Try the following: clean the lint screen, check if the vent run is crushed or kinked, confirm the vent run is free of lint and debris, confirm the exterior vent exhaust hood is free of lint, verify your vent system falls within recommended run length and number of elbows, select a Timed Dry heated cycle and restart, or have your entire home venting run cleaned if the indicator remains lit.
