My GE window air conditioner, Model AER10AT periodically makes popping noises

SOURCE: My air conditioner is making noises

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.

Yes it could be the pop off pressure relief on the compressor.
I assume it is the outdoor fan your referring to not running.

If this is a heat pump and it is in defrost (only in the heating mode should your outdoor fan be off and then for only a max of 12 to 15 minutes).
If it is just AC ir is Heat pump in cool mode, the out door fan should run while the compressor and indoor fan are on. Until the thermostat is satisfied on room temp.

This high pitched squealing is indicative of a bad fan motor or capacitor for the out door fan motor. Kill power and test blades to see if turns free. Check the run capacitor inside control panel. It is usually silver or aluminum colored (some are painted gray). The top should be flat with rolled edges and the sides should either be round or oval shaped with no swelling or oil leaking from inside it. If this all looks normal take it to where your going to get a motor any way and ask them to check it or sell you a replacement at the same time. These can go out usually from high voltage (lighting...) or from over heating (bad fan motor, dirty out door coil...).

Hope this helps you if not post back I'll respond as soon as I can. And please rate me as high as you can. Thank you for using Fix ya and good luck.

This might be the noise problem in your blower.The blower is out of balance with this added weight.

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.

Hi,
On many of the newer air conditioners they intentionally keep some water in there so that it splashes onto the condenser coil and helps to cool it....while this may work well it also creates more noise....so I often recommend to drill a drain hole in the back corner...jus drill down from the top...drilling up from the bottom is a great way to drill right through the coil....
