You must look into the machine and find where the noise is coming from. Only then can a person recommend what to do about the noise.

SOURCE: clicking noise from air conditioner when car is

That is the compressor cycling on and off. If it clicks every one or two minutes, this is normal and is necessary to keep the compressor from freezing up. if it is a constant clicking every one or two seconds, it is low on freon and needs service.

SOURCE: Roof Top air conditioner makes too much noise

Hello; Those roof tops can be noisy. Are you able to determine what is causing it? The fan? The A/C pump? Over tume, the vibration isolators that are rubber cushions the pump is mounted on, get weathered and hard and they no longer absorb the vibrations of the running pump. Those are easily chked and changed. The next point of excessive noise is the unit as a whole is tranmitting the combination of all the vibrating parts including its own housing. Here too we have a remedy. The roof unit has a seal between it and the camper roof around the hole it is fitted in. The seal is foam rubber and reasonably thick enougth to serve a purpose more than to seal out water and air. After and over time this seal ends up crushed from the weight of the a/c unit. Then the A/c unit comes in contact and is actually resting on yhe roof with what is now a very flat hard gaske. The roof unit is now vibrating the roof. This is as destructive as it is annoying. Ok? Now let's get rid of 80-90% of the noise. Check and replace compressor vibration isolator mounts. There are 4 bolts holding down the A/C unit. Sccess them from the inside by removing the ceiling trim and cover.There should be one on each corner. Bolts removed, one person push up on the unit and another on top lifting the unit. There are wires going to the unit and those may need to be disconnected. Clean the roof and the a/c where yhe seal goes.You can get a new seal from camping world or rv supply. Have your measurements, Unit make and model when you go.Assembly is just backtracking. On assembly, thinhs to pay attention to are:
Put the new seal on the A/C unit, not on the roof. It takes two people to ligft and set the unit back into the hole and center it in the hole. Don't slide it on the seal. lift it if it hs to be moved or the seal may roll over..
The wiring disconnected earlier must be dealt with and put in place for reconnecting.
Now start the bolts that hold the unit down.
Make sure-- Unit is centered
Wires can be reconnected
The four hold down bolts have their washers.
Someone go topside and verify the seal is properly in place. Measureing the for corners fo even height is one way to ck and looking under the unit is another. Now tighten the four bolts evenly. corner to cross corner. measuring again will help confirn its pulled down evenly. Pull it down no more than 1/4 to 5/16 of the seal thickness. Wire it up and put the trim and plastics back on and light it off. (run it and ck for noise and vibration. NOTE!!! The A/C unit cannot touch any solid part of the roof. Reason it was centered. Always ck the unit before each trip as you would any other psrts on the exterior of the camper. Good Luck Angie.

I have a neo plasma lg 7kw will not heat LG Air conditioner


Make sure the setting on the remote is correct . Sun symbol for heating. Make sure the filters are clean. On heating, the indoor unit will 1/2 open the flap but the fan shouldn't start. The outdoor unit should start and if working properly, will be blowing cold air. The indoor unit will open the flap fully and the indoor fan will start once it gets hot then you should feel warm air. If the outdoor unit is blowing warmish air, I would say the reversing valve coil has failed or one of the indoor temp or pipe sensors are faulty. If a sensor fails, a "CH" error should appear on the display.

Hi, you need to take out the whole air con and clean it, heres how to clean it, first open the case then wrap with plastic the power supply and the motor so that it cannot wet, then washed the whole area of the air con and dry it with high pressure air sprayer. then return back the cover and test it. hope this could be helpful. thanks

Air conditioner blower flapper stuck on defrost and not blowing out vents


This flap is controlled by a vacuum operated actuator. Either the actuator is bad, or there is a leaky or missing vacuum hose for it. Or flap is just stuck
