Question about LG Heating & Cooling

Well when I try to turn it on, nothing happens but only red and green light start to blink. The outdoor and indoor unit do not run. Its a three phase electrical connection and they are ok but the split does not run only the light keeps on blinking.

How many blinks look at the diagnostics troubleshooter usually on the panel of the unit, then determine the problem.

Luxpro psd111 thermostat shows snowflake (sometimes blinks), outdoor fan works, but no cool air comes out inside- no air flow at all. Is it the thermostat or an a/c unit malfunction?


If the outdoor unit is running the indoor fan should definitely be running. Turn power off to indoor unit. Put red green and yellow wires together behind the tstat with a wire nut. That is power (red), indoor fan (green), and compressor (yellow.) Turn power back on. This is bypassing the tstat and you should have indoor fan and outside running as well. If yes the problem is in the tstat, if no indoor fan the problem is in the unit. Good Luck!! Let me know!!

Why does my sanyo model KHS2472 has a red light blinking in heat mode and a green in cooling mode, does not work in either mode makes a gurgling sound when it tries to run?


Hi,
The red light indicates it's either heating or in defrost mode
Check the outdoor unit if the compressor is running - the large pipe on the outdoor unit should be hot on heating or cool to touch on cooling
When in heating mode - the indoor fan will not start until the indoor coil is warm enough
If the reversing valve that changes from heating to cooling is faulty then you may encounter the same symptoms too
Probably need a Refrig Tech to have a look at it?
Good luck

Don't understand outdoor self diagnosis code


This sounds like a fault with the inverter or the compressor motor itself,

System will not start up.


This is a signal fault between the indoor and outdoor first make sure the dip switches are set start with the unit closest to the condensor set as unit 1 then next unit as 2 and so on the dip switches are inside the indoor unit on the pc board if you check the manual it will tell you which swithes to set, if this wasnt done when the units where installed they would have never worked i would also check the signal wiring between the wallmount and the splitter box / bc box and make sure there isnt a loose connection when you have ruled this out id say more than likely it is a faulty indoor board on the wallmounted unt
