I just checked the manual for mine. Press the temp up/temp down buttons together to reset the light. It will come on again after 250 hrs of operation to remind you to clean your filter.

The audio system shut down due to a short circuit. This could be internal short or related to a damaged cable. Check that none of the cables are frayed or have damaged shielding. Make sure that the cables aren't contacting each other or the back of the audio system. If the short is internal, I would advise checking if the unit is still under warranty. Cindy Wells

Mine did the exact same thing. We unplugged it, waited for 10 seconds and plugged it back in. Everything is working fine now. If that still doesn't work for you, the customer service number they gave me for the split unit is 888-346-1923.

ice maker leaking?

Find a new AC engineer approved by LG. All AC Units leak a small amount at the compressor bearings and seals. It sounds like yours needs some sealant. and gas, or a new sensor. Diagnosis by an LG trained engineer is needed. https://www.google.com/search?q=3+zone+LG+mini+service+engineer ..

Has to be a stuck relay or contactor. I'm sure it's a relay on a circuit board so likely the whole board will need replaced. Never opened one up and don't see a wire diagram. But, if you need heating, unhook the compressor. Obviously wrap any bare wires, obviously cooling works but will have to turn off breaker to shut down. Temporary fixes obviously but will get you by.

It can’t be wired correctly. It should be a 4 wire connection, I would run a temp wire from outdoor to just one indoor unit and see what happens. The outdoor board may also not be programmed properly to pick up 5 heads. New unit should be under warranty.
