SOURCE: Lous Noise

It could be the blower fan is loose and needs to be tightened. If so, and you're handy, shouldn't be too difficult. Depends on the specific design.

SOURCE: Unit constantly makes a clicking noise.

Electronic filters use static dicharges to filter the air. Unfortunately the make that clicking noise when they discharge. LG calls it a plasma filter. Clean both the regular and the plasma filter to see if that helps.

SOURCE: My Air Conditioner makes a loud buzzing noise now. It didn't do that before, now it makes so much noise I can't hear anything over it

Buzzing noise - contactor. maybe a bug got in the contacts or maybe the coil is bad but in any case if you replace the contactor the buzz will go away.

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.

My sharp comfort touch air conditioner make loud noise from fan. It is very loud. I have 2 and both are very loud. I took the unit out of the wall to inspect, and could find nothing obstructing the fan.


Hi, you may want to check the bearings on the fan motor it self. They will wear or get dry and make very loud noises. Check the motor body at each end to see if this motor has oil caps at each end to add a few drops of oil. Some motors do and other motors have sealed bearings and when they go, there is not much you can do when they fail. If it does have a place to oil them, get the oiler at a hardware store. They come in a small plastic bottles that telescope to reach the bearings. This may take the noise away if the bearings are not already gone. Let me no what you find and we can go from there. I wish you the best,

Air conditioner fan is making a loud noise


1. Could be a caught foreign object between A/C (air conditioning) fan and cooling radiator, producing this loud noise.
2. Could be a damaged fan blade, mowing the cooling radiator.
3. Could be a loud noise comming from the fan's electrical motor.
4. Could be a broken off fin (small wing) of the cooling radiator, striking the A/C fan, producing this loud noise.

Compressor of the Ruud A/C outside unit is making unusal loud continuous noise. I open the case, its not the fan or fan motor, loud noise is coming from the compressor, and it is also heating up a lot....


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.

HEATER MAKING LOUD NOISES


Check the draft inducer motor for any partial blockages or dibri.

I've seen sticks, birds nest particles and pieces of deteriorating fan blades (squirrel cage type fans) cause this.

You might also find that the inducer motors bearing are going.

If its a loud vibrating grinding type noise, I'd suspect bearings or missing pieces of the blades. (unbalanced)
If it's a clanking type noise I'd suspect loose items hitting the fan.

The inducer motor will only operate right before and during burner operation, while the blower motor can operate at any time depending on your setting.

Fan making loud noise like it needs oiled


Most of the fan motors can be oiled. You will have the slide the ac forward and remove it from the case to access it. You will find yellow pull pins on each end of the motor, a lite drop or two is all that is needed.
