Question about LG LS-L1210CL Mini Split Air Conditioner

1 Answer

My in-laws just had installed an LG mini-split MFL42262811 unit in a room over the garage. When we turned it on this time and tried to get heat out of the unit...no luck. Unit says its in heating mo

I tried doing a self test. The unit kicks in the AC fr 18 min then shuts off fine. I pulled the batteries out of the remote and used the on/off switch and the unit still fails to blow out any warm air. The unit is less than 6 months old.

Look for burnt wires or maybe the a/c runs with heat

I don't think you can turn of the beep. Not without tearing it apart and removing the internal speaker, is it really that important? The temp sensor is in the unit.

SOURCE: My LG LAN125 mini split heat pump occasionally

Wash out your outside coil and monitor the outside fan. sounds like a lockout due to dirty condenser or intermittent motor operation. Could mean condencer air problem.

SOURCE: LG Ductless Mini Split System LAN125hv: Heat pump doesn't run.

First check your circuit breaker or fuse that supplies power to the outside unit. It's probably separate from the inside unit. Then try to turn unit on. If the fan and compressor just make a humming sound then turn it off and check the capacitor if you have a multimeter. You can also look at it and see if the top looks expanded. That's a good sign its bad, but not all bad one's look expanded. Tomorrow I will have access to an LG service manual and can let you know what the code means. Sorry I can't get it sooner. Let me know what you find.

Why won't my lg ductless heat pump regulate the room temperature?


After I have been reading up on your unit it appears that the thermostat is not operating correctly. I found this real basic information on installation for your unit. This link I am giving is pretty basic instal schematics. But seems to be something about your thermostat needs to be dialed in or is not working properly.

From my experience mini splits are a very quiet unit. You may need to check local code though, and consult your neighbor first. Better to be proactive over making an enemy.

Hello.I think they are on to something with shortcycling on temp sensor.I think it should be sampling the return air instead of (inside coils ?).A 2*f dead band use to be built in (factory installed) to thermostats to prevent on/off, but not sure in this case.Try a new sensor location(return air) and see if anything changes.

Should the LG LS-K-1830CL outdoor unit ice over on the coils when operating in the heat pump mode? Would this cause the unit to not properly heat the room?


Running the heat pump in low outside ambient temps. will definitely cause the coil to ice up. An ouside temperature senor or a wind baffle should be installed in climates that get below freezing. This would definitely cause the heat pump to operate at lowered efficency and maybe not at all. It should go into defrost mode if the sensor is working correctly when the coil ices up.
