This is not a split system a/c unit guys. Look at the picture. The blinking light means the air filter may need cleaning. Reset power to turn it off.

I have a split unit that was installed about 8 months ago. It worked fien until the hot summer came. Suddenly it began to drip on the wooden floor beneath it. I checked the drain outside and it seemed to...

If your unit is only 8 months old, then it should still be under warranty! Suggest you check the drain line to make sure that nothing has decided to make it home.

I would check the level of your unit to make sure that there is a slight grade to the rear of the unit, but I hesitate to tell you to shim it.

Have an S30 AHP ND-6 split system a/con. Runs fine until second stage kicks in then it drops out the breaker in the main fuse box. ANy ideas?

Sounds as if the rotor in the compressor is grounding out to case. I don't see this very often
but it does happen. It can be intermittent but gets progressively worse until the unit will not
function. It also will run the utility bill up significantly.

We have 2. LA125HV w/ 1 condensing 1. air handler

I could not find a "fault code" list for the LA125HV but for thier Multi Split Units LG lists code CH7 (C7) as "Indoor Unit is Set in Different Cool/Heat Operation Mode." So maybe your air-handler tihinks it's in Heat mode will the compressor is in Cool mode, or vice-versa....
