Question about Whirlpool ACQ158XP Wall/Window Air Conditioner

1 Answer

Thru the wall ac unit

The unit is making a whining, clattering sound, like something is loose. Could it be the fan? Could it be froze up? It almost sounds like the fan`s off- balance, sometimes it starts after a bit of whining and it sounds ok, then other times it sounds horrible, maybe like it`s stuck. Help, anyone? Thanks! Also, the mfg date is 2004, so it`s not that old.

Sounds like the fan shroud on the hot side has come loose, or something is rattling around inside. Looking through the exterior vents may reveal the trouble, but the unit will have to come out & have the cover removed for repair. You can try lifting the outside corners one at a time while the unit is running & see if the noise stops. If so, a shim wedged under that corner will hold you for the season.

Why does my ceiling fan sounds like a clacking sound.Could a cluch be loose or something else.

Yes, that's very likely a dropped screw or something. I suggest you [get someone to] disassemble it and figure out what is causing the clatter before it does something really tacky.

If your a/c have a housing, set the upper front side 1/2" away from the wall and the lower front side 1 1/2" away from the wall. Some units with plastic base pan should be inclined more defending on the height of the drain line fitted in each model.

Has it always made that noise? If so then I would think that after 4 years and no problems that it is nothing to worry about. If it is something new then turn it off and call a service tech to look at it. I am leaning toward the service tech.

Loud rattleing sound

If this AC is a thru walled, since it is new it is better to inquire to the people where you buy this unit, for this type of problem. They must have some authorized repair man/shop or, use its product warranty.

The problem could be also uneven placement of its base. This could maybe hitting the fan guard, some loose connection or some foreign object left that's hitting something inside.

Ac wont turn on

It sounds like a bad contactor. The t-stat is sending voltage out to it, but it isn't allowing voltage thru it. You should have the same volts in and out after it "clicks".

Hss25gfpdww The unit makes a horriable high pitch whining noise a

I am not posotive, but it sounds like you may have a piece of debris stuck in the fan underneath. You can check if you pull it out from the wall, make sure you unplug it as to not have the fan come on while you are toying. But thats what it sounds like. If that is not it, I am sure you could locate the noise with it pulled out from the wall, and go from there, Possibly your compressor, but sounds like the fan the way you're explaining it. Good luck

Haier ESA 3185 AC won't cool; makes escalating loud vibrating noise near front panel/ filter

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.
