Which Arctic King units show LL

This page applies to Arctic King Arctic King single-zone and Arctic King multi-zone units on the indoor unit display (four-character codes). Arctic King's own documentation lists LL as "Remote or wired controller locked", the same definition used across the Midea platform (four-character 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 Arctic King shows this code

indoor unit display (four-character codes): The display shows a two-letter prefix and a two-character suffix, either together (EH60) or alternating (EH, then 60). Write both parts down; the suffix is what identifies the fault. EH and EL are indoor-side faults, EC is an outdoor-side fault, and PC is an outdoor protection: the unit stopped itself to prevent damage.
