Question about Fedders U Chassis A7U12W2A Air Conditioner

1 Answer

Fan is making clunking sound like it is hitting something.

After AC is on for awhile the fan makes a clunking sound which is worse at medium and high speeds. If I turn it off for 1 hour or so and restart it works OK for awhile and the noise starts again. Could this be ice forming? Other than this noise the AC seems to work OK.

Yes, it certainly can be, especially in high humidity. Run AC just about 1/4 way from max and crack the windows. The ac will work better and ice up less.

When I turn on my ac on high and medium a very loud rough grinding comes from under passenger side dash


You could have something caught in the interior air fan, it could be loose or broken, or it could have a bad bearing. Without knowing make, model and year, can't tell you much else to look at.

Maybe the blades are hitting somewhere when it is rotating, otherwise, it could be bad bearings. Is it a store brand (Hampton Bay,Harbor Breeze or hunter fan sold in box stores)?

Hi,
Those squirrel cage fans have a habit of coming apart, or getting dirt in them and going out of balance...then they wobble and hit the sides of the fan housing...
Make sure the fan is clean and also move it around a bit to make sure it is not coming apart....
Often the only way to fix them is too replace the sqirrel cage part...

Noise problem CXL52WB


mcdevito75 here, From the little I know about these ceiling fans, they are a sealed bearing type motor, you may be hearing a dry bearing on medium speed for which you"d have to replace the fan to fix. Or, you may be hearing vibration of the fan itself when it"s on medium, vibration could be the fan itself or something slightly loose. Have a handy man take a look at the fan and it"s hook up, make sure everything is tight. Hope this helps.

Water doens't drain properly and sitting there,


that's fairly common for window units, it's ok to drill a small hole in the underside of the case to drain the water, just be sure you don't puncture the condenser in the process.

Hampton bay fan makes squeeking noise


If the fan is fairly new, remove it and return it to Home Depot. It is almost certainly something that has fallen down into the motor and is rubbing loudly enough to make a squeak as the fan runs faster.

The fan itself has sealed lubrication and you don't have to lubricate it.

Lasko 5365 heater making growling sound.


sounds to me like you have a fan blade hitting something inside the unit, or the motor is going bad, thats the only moving parts to the unit unless it has a sweeping mode, moves from side to side, if it doesnt have that, then its your fan motor or blade, you probably need to replace the motor or the whole unit, as they are fairly inexspecive, but its your call, look inside the unit to see if anything is in there that might be making the noise as well, best of luck, hope that helped
