Outside unit will not operate

A few days ago I noticed a loud squeeling sound coming from the unit when the AC was running. I turned it off because I was pretty sure something was wrong. Now, when I turn the AC on I can hear the unit make a humming noise when I stand next to it. I've reset the circuit breakers and they didn't fix the problem. If I run the fan inside the house the humming is not present. Any suggestions or ideas would be greatly appreciated.

    Well I rent the house I'm currently in so I was curious about maybe an easy quick solution to solve the problem without having to call up the landlord. I guess I'll go ahead and give them a call.
    Thanks for the information.

    After doing some more research I believe the capacitor is bad. The condensor will run but when it's time for the fan to run that's when I hear the loud noise and the fan doesn't move. Can you tell me where I could purchase this hard start kit and how much they are ?

    I also noticed a loud squeeling sound coming from the AC unit when the AC was running yesterday. Not sure when it started but had turned it on about 1 hour before i heard the noise. Never heard that noise before. I also turned the AC off because it sound like something was wrong. Now, when I turn the AC on I can hear what sounds like the compressor running but fan is not spinning and then the squeeling sound starts. While off, i can spin the fan. If it's a capacitor problem where is it located and is it and easy inexpensive fix. I also reset the circuit breakers and they didn't fix the problem. Any other help would be appreciated. Thanks

Sounds like a bad fan motor. Inside fan runs, compressor runs. Outside fan. Are your contactors pulled in when thermostat set on cool? If not might be a contactor. If contactor not pulled in touch the top of it with the end of a screwdriver. If fan spins turn unit off a buy a contactor...

Tip: Always make sure power at disconnect is off

Sounds like your compressor has frozen up or is not getting the required voltage to run. One option might be to install what is called a hard start kit which is a capacitor. If this does not fix your problem most likley your condenser will need replaced. Another thing might be an overcharged system which could happen as the temperature has increased outside. Unfortunatly this will probably already have caused damage to the compressor. Please comment if you need further assistance.

    you may purchase these kits from a Johnstone supply or grainger supply or even maybe a local HVAC warehouse in your area.

Unit not working correctly. The unit worked for the winter, few days ago I turn on the AC and noticed that it wasn't cooling like it should.


It's could be the board or a heat relay. See if you have 24 volts on "x2" im assuming, emergency heat when in cool mode if so it's the board. Or unhook black or x2 or your emergency heat from board and run unit in cool. If heat stays on its a relay

Condenser fan replaced one year ago, fan not turning but can hear motor


the answer to your problem is most likely the motor start capacitor. A AC motor can run in both directions. The start capacitor is used to cause the current to lag behined the voltage which determines the direction the motor will turn. Its posible the start and run capacitors are in one can. so changing one will change the other. However look for a wiring diagram. Do not asume that both capacitors are wired in properly. They may be fighting one another causeing premature failure.

AC BLOWS WARM AIR


Cooling comes from what is done outside, if air handler is blowing and you are hearing a sound , may be in the duct work. If you feel warm air in cooling mode then the outside unit is the prob, need more info

Ruud heat pump question


Does the air handler take a minute or two to start, this would be normal so that it doesn't blow cool air into the house before the unit is warmed up. If not could be the fan relay is weak and needs replacing. As far as the outside unit it sounds like you need to check the refrigerant. In cooling they are 70/150 psi. This should be checked in cooling mode, once you turn it to heating mode the pressures switch bring heat inside the house instead of out. I hope this helps.

Squeeling noise coming from AC, compressor is on, fan not turning


The squealing noise is coming from the compressor. This noise is common when the unit reaches extreamly high pressures. The pressure is most likely high because the fan is not running. Since you can spin the motor it could be that the motor has damaged windings. Leave the unit off until the repairs are made to ensure no further damage to the compressor. You will need a multi meter and some experience reading wiring diagrams to properly diagnose the system. You can perform an amp draw on the motor to see if it is in spec. You can measure the volts to the motor and see if they are in spec. Finally the contactor can be measured with the proper meter to see if it is working properly.

My suggestion is to have the Motor and capacitor both replaced. Also inspect the wiring in the condenser electrical compartment for any signs of damage or burning.
