CL: Clean filters

CL is a clean-filter reminder, not a breakdown. The sheet says it appears after a set number of hours of fan operation, 500 hours on most models. The unit is asking for a filter cleaning. Clean the filters. If your model has no filter-reset button, turn power off at the breaker for a couple of minutes to reset the reminder. It also clears on its own after about 72 hours. You do not need a technician for a CL reminder by itself. If a fault code such as an E code is on the display at the same time, follow that code's page, and call support if the fault stays after the breaker reset.

Filter cleaning is in the full maintenance checklist. The steps below are the reset. The full maintenance checklist covers the filter cleaning itself.
