Whilepool model gs6shamb00, Why a few second after the compressor shut off, the compressor knock loudly? The evap coil also shakes for 30 seconds to 1 minute. charlie T


I had accidentally overcharged a unit with freon one time (r410a freon), and when the unit stopped, the compressors rotor would spin backwards and make a loud "knocking" noise. This was on a scroll compressor, not a reciprocating compressor. Also, most compressors have a check valve, allowing freon to circulate in 1 direction only. And if it fails, when the compressor stops, the freon will rush opposite its normal direction of flow, and will sound off as a knocking noise(again, I've seen that on a scroll comp). That may make your indoor coil shake. I've seen/heard that make the copper lines shake but never the coil. Hope this helps! And FYI... Most ac service techs can check "superheat and subcool" as well as freon pressures. Without checking these 2 temperature measurements, we are just guessing as to how much freon is in the system. Make sure to ask politely beforehand for your service tech to do so PROPERLY when he checks the freon levels per factory specs, which should be on the units technical data located on the outdoor unit.

Why is Mr Slim MS-SGF24VC outdoor unit working when indoor unit off


Possibly a bad control board in the outdoor unit. Pull the disconnect outside to stop machine, wait 10 seconds and out back in. White mist was likely frost built up on indoor coil due to condenser running without the fan.

Hi. I recently installed 1.5 T, 3 * Split AC, LG. Whole day the AC works fine and no problem in cooling too. But once in 2 day outdoor unit start making thudding noise continously and does not stop for 4...


Hello

Sounds like the compressor is shuting down on high heat.There could be a couple reasons for this.
1 Check that proper voltage is being supplied to compressor.
2 Freon level may be low.This would be a service call.
3 Bad or intermitent connection at thermostat.
4 Main contacts to compressor sticking,usually burnt or pitted.

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!

Power issue.


James,
I have been researching this TV and found that many had motherboard issues with this exact problem. The fix was to replace it. I would contact LG support ASAP and get it to a service rep before the 1 year warranty runs out. Good luck!
