Compressor fan seems loose and makes noise To add more, the problem get worse when I change the balance of the conditioner. Sometimes it gets better too but not for long. It only does this when the conditionner is working so I assume it's a fan in the compressor. Thanks

with loud noises and underperformance a complaint , me id be looking more at the fan part of this machine , wall units get a lot more dirt and stuff inside them then other types ,especially if there low on the wall . so its entirely possible that items could be wedged down inside that has effected the balance of the fan blades , and this is cause for lots of noise complaints , plus if items are large enough then yes they will effect the speed of fan as well

Hi, have you tried moving it to somewhere else as it can be noisy depending on what type of surface its on, as this can cause it to vibrate

Year make and model ??
The belt could be glazed and slipping even if it is tight.
You could have a weak belt tensioner too.
The noise when the ac or heat is turned on can be the extra load from the ac compressor or the alternator. The compressor cycles on and off especially in defrost mode.
The load from the alternator is the first noise of the day. As the belt warms up it becomes better at handling the load of the accessories.
Even tho the belt looks fine, you may have to replace it to get rid of the noise.

Hello, the noises you are hearing can be a few differant things. It could be the condensate being pcked up and splased on the condenser which makes a swishing sound, this is normal. It could be the fan blade hittting the shroud and that happens when the fan gets loose on the shaft. It also could be the compressor itself if liquid refrigerant is entering the compressor,

Hi,Whynter Portable Air Conditioner has many moving parts, and they all make noise and cause vibrations. Some of these parts are more likely to causing shaking and loud noises, and sometimes this signals a larger problem, something to watch and scrutinize. If serious enough, it calls for a repair.

Loose Parts

Loose parts cause the majority of shaking and vibration noises in your air conditioner. A few of the most common loose parts include the air compressor, the piston rods and even the fan or blower unit itself. These noises are clunking, clanking sounds that occur along with a vibrating action. The only method of repair is a complete compressor replacement, which is a repair only a certified air conditioner technician is qualified to make. The compressor is a fully sealed component, so individual parts in the compressor cannot be repaired.

Fan Blades

Fan blades cause noise, shaking and vibrations even when properly secured. If fan blades contact the exterior structure of the air conditioner due to a bent fan blade or broken and misaligned grate, a constant, repetitive noise and vibration results, which sounds like a ticking or banging from the interior of the air conditioner. Vibration in this case is limited but still present.

Mounting Brackets

When an air conditioner shakes, there is a problem with the mounting brackets. These brackets hold the air conditioner compressor steady as it operates. Normal vibrations and shaking would otherwise occur without these brackets. A loose mounting bracket causes the air conditioner to rock back and forth and creates a clanking sound. As the compressor starts up, this rocking and clanking sound begins, resulting in a very loud and fast vibration and noise. It also occurs when the unit shuts down.

Other Sounds and Vibrations

Sometimes air conditioners squeal, hiss, hum or screech. Each noise is often accompanied by a vibration. Humming sounds along with a vibration may indicate a bad capacitor, the electrical part responsible for starting the machine. Hissing sounds tend to indicate a pressure problem while screeching and squealing sounds are fairly common in window air conditioners and in central air conditioners. This sound is also a result of the compressor motor. It usually starts when the unit turns on and continues through its normal operating cycle. Vibrations always occur in the air conditioner due to moving parts and the compressor motor's operation.


Hope it helped..

CHECK FREON LEVEL...IF GOOD CHECK FOR DISCONNECTED
THERMOSTAT OR COMPRESSOR OR CONTACTOR WIRE AT OUTDOOR UNIT WITH POWER OFF. CHECK FOR A BLOWN CAPACITOR OR UNIT GROUNDED OR BURNT WIRE. BAD BREAKER OR SEE IF OUTDOOR FAN COMES ON AND COMPRESSOR KICKS IN ( MAKES WHIRRING NOISE ) .

INSIDE CHECK BOARD FOR BLOWED FUSE, GROUNDED WIRE, MAKE SURE SYSTEM IS GETTING 24 VOLTS, IF NOT CHECK THERMOSTAT WIRES OR TRANSFORMER ON INDOOR UNIT.. IF YOU SET THERMOSTAT TO OFF AND ON AND THE INDOOR FAN COMES ON..YOUR GETTING 24 VOLTS.NOW YOU NARROWED TO THE BOARD OR LOOSE WIRE, FUSE OR THERMOSTAT. IF YOU TURN YOUR UNIT ON COOL AND AUTO AND THE INDOOR AND OUTDOOR FANS COME ON AND THE COMPRESSOR KICKS IN
BUT IS NOT COOLING...CHECK AND POSSIBLY ADD FREON...
ALSO CHECK AND MAKE SURE INDOOR BREAKER IS ON.

Without being there to see it and have only your description in front of me, it sounds like the fan blade could be out of balance.......but it sounds more like a loose fan blade hub. Most Goodman units offer a minimum 5 year parts warranty. The Labor warranty is questionable, but the installing contractor or the Goodman Distributor should be able to give you that information. Of course this would cover manufacturer problems and not physical damage. As far as a history of this problem with Goodman..........I've seen it with every brand. If there is a problem getting it under warranty, you might be able to purchase the blade yourself. Before replacing the fan blade, I recommend disconnecting the motor wires from the contactor, tape off the ends and remember exactly where they were attached.....then start the unit to see if the noise is still evident, if so, it's probably your compressor. I recommend a certified repairman....not the one that quoted you $800.00. If you hear only the compressor start up and not the loud noise you are discribing, then try replacing the blade first.

I hope you find this information to be very helpful to you. :-)

I believe the 6SBAR has an evaporator fan located behind the evaporator plate ( the cooling plate) inside the unit. They had some issues with the bearings in those fans failing and will sound like a small jet engine sometimes (high pitched whine). When you hear the noise, open the door and if the noise level changes (either gets louder or goes away) then it is the evaporator fan. If your noise is coming from the compressor area and does not change when you open the door, it is most likely the condenser fan blade is loose. The evaporator fan looks like a small computer cooling fan and is located near the bottom center of the evaporator plate (out of site). The factory sells a replacement kit with a much better fan and new power supply. You can reach them at 800-223-3900. Good-luck.

does the fan wobble at high speed? if so change the order of the blades to try & balance it.i.e. number the blades on a piece of tape on each--switch blade # 1 & #3-better or worse? 2&5;better or worse?etc. untill it runs smoothest.

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.
