I'm not sure exactly what unit you have and what controls you have installed on the unit. But....there usually is a flash code schematic on the unit. Usually on the inside of the blower compartment cover. This should tell you what is wrong with the unit. It could have a low voltage short somewhere and is loosing the call for cool. So the answer can be a possible yes to your question but without knowing the flash code, it's hard to tell from my point of view. You might end up calling a service professional out to check it.

pls try to lubricate it if it got oiling port as soon as possible. if no port you may change bearing before the damaging motor . also if this type of motor does not have bearings better to change it

SOURCE: Compressor of the Ruud A/C outside unit is making unusal loud continuous noise

OK, you will need to replace this compressor. the internal seals have ruptured, causing the loud noises. the heat is from the metal to metal friction. the compressor can be rebuilt but, it will be more costly than just replacing it with a new compressor.

SOURCE: Noisy indoor air conditioning units

Ok. So first things first. LG have a reputation with all their products. THEY ARE ALL BAD! If you remember GoldStar, they are now LG. GoldStar had horrible products. Now this is what LG has. The fact that the filters are cleaned and the units are serviced is an abosulte plus and will provide the units with extra longevity. Now are these drains are they used for water drainage. If so the upstairs units shouldn't need them unless there is some sort of rise in the drain pipe.

Now to the noise. It seems like there is something which is causing the fan to make a noise. It could be loose bearing or a piece of the fan which has broken away causing it to hit the inside of the unit. Since it is on both units, it would be a generic problem with this series and unfortunately is what you are stuck with now.

To combat this problem, I would: ring LG and the company who installed them and demand that they be repaired and have a warranty on the repairs. Just a heads up, LG are really bad to contact should you have a complaint, so keep persisting that they be repaired free of charge since that they are still under warranty.

If you are not happy with LG or your installers response, I would remove the units and have another brand put in. I recommend Mitsubishi Heavy Industries and Panasonic. Both units are whisper quiet. In fact they are quieter that the LG.

Oh and that only reason why LG boast about their "whisper quiet-ness" is because that is probably the only good going for them - and thats' not even right!

I hope that I have helped you in some way. Good Luck!

I have a LG minisplit (indoor unit LSN122HE /outdoor unit is LSU122HE) it cools great dehumidifies also and has for 3 months of summer. However its cold now and it will not heat. It runs for a min out


That's an inverter series motors... the outdoor fan motor is on an ambient controller to maintain pressures when cold outside in air conditioning mode, but not in heat...only defrost when needed. Check the settings on the outdoor board for defrost timing

Check your air filter and indoor coil fins if clean. If it is dirty it need to be clean. But if it is clean you need a qualified technician for this problem.
