Blower is making strange noise almost deisel engine like sound

I bought this unit last year and only used it about a dozen times- I turned it on this year and the blower is making a strange noise - almost like a deisel engine- its herd louder than the compressor in parts of the house - does any one know why this may be happenig? I know the unit itself is fairly loud ( any thing but the whisper quiet operation they claim) but this noise is really loud now and its directly coming from the blower/or motor wether or not the compressor is on or off.
Please help!!

SOURCE: Compressor noise

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. Hack

SOURCE: 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.

SOURCE: strange straining sound

Either compressor is going bad or the fan is rubbing. There is a condensor fan that comes on only when the compressor starts. So check the fan out first to make sure that it is not rubbing or moving around. If that is not then check the compressor by letting it run for about 5 minutes then touch the top of the compressor. BE careful as it can be extremly hot that will show you one of two things either bad compressor or condensor is dirty and a garden hose with a jet blast of water will solve the problem. If that doesnt work either compressor is bad and will either need to be replaced for about 250 dollars or unit will need to be replaced

SOURCE: A.C . makes a buzzing noise...

If you can make repairs yourself a motor is only about $40 and a capacitor about $10. Either could be the problem. If you have to pay someone to do it buy a new one.

2008 vw jetta makes noise from blower


I would say your heater core has a leak and needs replacing. Moisture is getting into your blower motor and it will seize up if you run it that way.

I have a 2004 Impala. when I turned off the ignition myheater blower stayed on what can i do tofix it cheap?


More than likely the resistor for the heater motor is causing the problem
it is located behind the heater motor under the dash on the passengers side. If the heater motor is making noises it may be drawing to much and caused the resistor problem.

Whenever I turn on my air conditioner, my car makes a roaring or rubbing noise. What is it?


Sounds like the clutch in the compressor which would usually be in the front lower portion of the engine on a pulley on the front of engine (passenger side on front wheel drive cars - and tubes are connected to it.  When engine is off spray with some lube but not on belt - allow to drip of for couple minutes.
Try that couple times and start car in between times using the air conditioning.  Not sure if you can replace the clutch unit or have to replace the compressor as a unit which would lose the Freon or R2 or whatever the new stuff is called now...
Hope that helps.

Weird sound coming out of the rotary unit inside gas heater


It may be your inducer motor making the noise. If there are any hoses hooked to the housing, make sure they are clear of blockage and moisture. Look for any way to drip a few drops of oil onto the motor shaft, it may help. If the unit is more than 10 years old, you might as well change the inducer motor as a precaution. It will fail at a most inconvenient time anyway.

Possible Contactor Issue


Sounds like a bad fan switch in your unit. That unit has a fan board in it that is time delay on and off. Turn the fan to the on position and let it run all the time. If it keeps temp and does not shut off it is the fan realy board. The board also controls the compressor. Check that first and then the tsat. Russ
