What CL means on a KeepRite

A run-hour timer has expired and the unit is reminding you to clean the filters. Nothing is wrong; the unit keeps running.

On this platform, CL is a status, not a fault: the unit is telling you what it is doing; nothing is wrong.

What to do

You can almost always clear this yourself with the steps below.

  1. Wash the mesh filters behind the front panel, let them dry, and reinstall.
  2. Clear the reminder using the remote: on most models press and hold the LED or Reset button (see your manual), or turn the unit off and back on with the remote.

When to call a technician

This is not a fault. No technician is needed unless it will not clear.

Which KeepRite units show CL

This page applies to KeepRite DLCSRA / DLCSRB / DLCLRA outdoor with DLFSHA / DLFSFA indoor (2015 and later) and DLC4 / DLF4 (2013 to 2015) units on the DLC/DLF series, 2015 and later (Midea-built). KeepRite's own documentation lists CL as "Filter cleaning reminder", the same definition used across the Midea platform (classic codes) it is built on. If your unit shows a code with a different shape (for example a four-character code, or a plain number), it is from a different table; use the lookup with your exact code.

Where KeepRite shows this code

DLC/DLF series, 2015 and later (Midea-built): The code appears on the indoor unit's LED display in place of the set temperature. Some models also blink the indicator lamps in a pattern that matches the code. E codes are faults in the indoor unit or its communication link, F codes are faults on the outdoor side, and P codes are protections: the outdoor unit has stopped itself to prevent damage. EC is the refrigerant leak check.
