What "Outdoor Unit" Message means

The words Outdoor Unit on the wired remote of an LG air conditioner that shows CH codes show the operating status of the outdoor unit. This is not an error. It tells the owner that the outdoor unit is running or is in a particular operating state, and the message sits among the other status icons on the remote. Owners sometimes see the text and worry that the outdoor unit has a problem, when it is only reporting that it is working.

Common causes of "Outdoor Unit" Message

Normal outdoor unit status display on a wired remote

✓ One safe check you can try

1. Check whether the unit is cooling or heating as expected. 2. Leave the message alone, since it needs no action. 3. Note any real change, such as warm air in cooling mode. 4. If the room does not cool, switch off and arrange service.

! Why to stop there

If the message appears with no cooling at all, we test the outdoor unit operation, not the message.
We check the remote display if the text looks wrong.
You get a written price first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
