Haier ESA 3185 AC won't cool; makes escalating loud vibrating noise near front panel/ filter
Haier ESA 3185 AC won't cool; makes escalating/progressive loud vibrating noise near front panel/ filter for about 3 minutes then stops as fan continues. Fan is keeps running. No cool air any time and air seems slightly "cooler" when vibrating noise is happening.This is an Energy Star a/c that shuts off compressor after optimal temp is reached, and this problem sounds like the compressor is shutting off, but the vibrating rattling is MUCH louder, sounds internal. Help?

Have someone check the run capacitor of this unit. If the run capacitor is bad over shorted it can cause the unit to run and short cycle on a current overdraw. This makes for an electrical imbalance in the compressor motor. Next step is the compressor is faulty.

Make sure you let the unit run for a bit before you judge too harshly but if the filters are clean and the machine is new there is a good possibility that the one of the components has failed like the compressor. If you just bought the unit I would return it to the store to have them replace it.
You are required to get the AC serviced which you can do it yourself except the checking of cooling gas.
Unplug the power cord. Remove the AC from the frame. Take it near to a water point where it can be washed.
Remove the front filter and clean it with a mild soap solution.
Next take a water pipe and spray water jet in the air vents/fins.
Let it dry.
For cracking noise connect the power cord and run the AC locate the noise.
If it is any loose part fix it or provide necessary packing to avoid vibration noise.
When you are running the AC check if there is moisture condensation on the cooling pipes. If it is there then the gas is OK otherwise you have to top up the cooling gas.
If the sound is coming from the compressor then you have to change the compressor.
Re assemble if you are satisfied that the gas and compressor defects are not there.
Had same problem with Ge AC. Unplug take out of window and remove all cover screws. Pull up on cover and pull cover off ac, Remove front cover as well there are a couple screws in the front. When looking at front of ac, hit the Styrofoam housing towards your left (towards control panel). Spin fan blade to make sure that it is clear. Plug in to double check. I put a couple quarters between the styrofoam and the metal housing, so it would not slide back. Also tape the styrofoam between the seams this helps with better cooling. Use some good tape nothing cheap. I used black duck tape. It took about 20 mins. The hardest part is re installing the AC.
Is it installed in a window? Check to make sure it is installed correctly. usually there is a felt or foam strip that is used to dampen vibration when you place it in the window. It also acts as seal to keep outside air and bugs out. If you place your hand at various locations on the unit does the sound go away? If it does then you know it is a vibration problem. Just add new foam or re-adjust the foam or gasketing it already has.
If that doesn't work then try to locate the source of the noise. Use a mechanics stethoscope or even a cardboard tube from paper towels will work. Once you have located the source then you can tell the store what the problem is when you take it back and get a new one.
Cheap air conditioners are noisy. Some more than others, it's why they are cheap. But your problem does sound like it could be a product issue.
Anything bought from a retailer you have 90 days (unless otherwise posted) to exchange according to the Uniform Commercial Code of the United States. There are other state laws that vary from state to state.
The air conditioner may fall under electronics, which usually have a 30 day return.
After that period you have to warranty thru the mfg. If you have a receipt exchange it, if not your out of luck.
Haier is garbage BTW. At least by the chinese made unit rebranded to look American.
First you need to make sure the filter is clean to allow good air flow through the evaporator. If the filter is clean make sure the evaporator is not plugged up with dust and lint. If all that is ok your problem is the a/c BTU's is to big for the size room you have the a/c in and it is getting the room too cold. If that happens the evaporator will ice up and will not cool the room.
