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!

My heat pump started making a squealing noise at all fan speeds. I think it may be the fan or motor bearings. It was running continuously last night. It is 32 degrees outside.


Assuming you mean the indoor unit, you're no doubt correct. Modern fan motor bearings can't be lubricated. It's a new fan motor to fix this. It will run with the noise for a few days, then lock up totally.

You should also report the continuous run to your HVAC repairman. At 32 degrees outside, I would think there should still be enough output from the heat pump to cycle. Perhaps low on refrigerant or a compressor that's losing. He could check both before you decide on the fan motor replacement.

15-20 years is about the max life on that unit. You may be better advised to replace it than throw a few hundred dollars here and there into repairs.

Ticking Noise in my Fujitsu Mini Split Indoor Unit


does the ac continue to make the noise even in fan only mode or is only in cooling mode. If only in cooling then it could be a gas related problem or blocked coil.

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

Minisplit flashing code - water dropping


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.

vulcan bonaire comfort control External natural gas electronic ignition 2004. ISSUE: Fan blowing only cool air continuously. Forced to kill power to stop it. model is one of the following. MB514E,20E or 30E. Going by mech drawing parts list. i can confirm what type of sensors i have cleaned with very fine sandpaper. flame sensor PN 5441603SP and IGNITER ELECTRODE PN 5441602SP The fault code i see is described as the following. There are x4 LED's. Sequence Left to Right. LEGEND: 1 Flame Sensor 2 Pressure switch 3 OverTemp 4 Diag. R Red G Green S Solid Colour B Blinking LED Behaviour. In order 2RS & 4GS Until i hear ignition. 2RS & 3RB Duration: split second 2RB,3RS & 4GB Duration: split second 3RS & 4GB Duration: Until it has completed blinking x4 times. 3RS Duration 4 seconds Repeat last two mentioned behaviour. in my own opinion, as a safety feature, the unit thinks that it has overheated or is about to. so kills the gas and force feeding cool air to heating components to save it from frying. Does this mean i have fault 04 if so does this mean i may have a faulty igniter or flame sensor or maybe a faulty as described in the mech drawing SWITCH OVER TEMPERATURE 120 degrees celsius. Am i correct here? Is this the over temperature cut out switch? if no one can really pinpoint which part requires replacement, can you at least, in sequence advise which parts to purchase? so then ill just try my luck. i wonder how to properly test if flame sensor, igniter, over temp etc is faulty with a multimeter. do i just perform a continuity test. I wonder what other parts can i test related to this fault im getting.
