Question about Danby DPAC12031 Air Conditioner

1 Answer

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

The compressor is extremely loud. How do I fix this? Also, sometimes it does not warm up like usual, what can be causing this?


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

Hair window air comditioner is making funny noises


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,

Whynter Portable Air Conditioner Model: ARC-14S. Problem: It sounded as if something fell inside the unit while it was operating (cooling) then it started to vibrate horribly. The vibration is only...


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..

I have new Samsung 1.5 Ton Window AC ( around one month old). Whenever AC is switched on in FAN or Cool mode the AC (probably FAn motor) make irritating Humming Noise. The noise slightly reduces after...


It is possible that your AC is not getting the right voltage or frequency and hence is trying to scavenge in gettting the current. It will be good if you can check on the mains voltage or on the wiring for a good 15 amp supply line. If there is any reduction or load onthe wire then the voltage can drop considerably. So in the first place kindly check this out. If this seems in order you will have to check for the fan or the compressor motor to be humming. If your cooling seems fine then you can check on the capacitor of the fan or the starter motor. I am sure since this is in warranty you must make a claim to get a free replacement. Hope you find my advice useful Good day

Does not cool


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.

3 year-old Goodman compressor/heat pump terribly loud @ start


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. :-)

Fan is making clunking sound like it is hitting something.


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.

I have a Coleman 5T 13 Seer Heat Pump. When the unit is running there is a lot of vibration (outside unit) and I hear a tinny sound (possibly like the fan hitting something). This seems to be worse...


First thing I would ask is did they locate the leak in the system before they recharged it? Your answer is YES to all three of your questions. If the unit is overcharged you can get what is called a liquid flood back to the compressor and this condition can cause compressor failure. Fans are balanced at the factory when manufactured. If a blade is bent or damaged it will throw it out of balance.
