Outside unit will only run for a short amount of time with A/C before the fan stops turning and starts humming, squealing/screeching and the top of the outside unit gets hot.


The bearings are bad in the motor and after the fan runs enough it eventually gets hot, making the bearing screech and the fan locks up. Need to replace motor again. See if it has a warranty. The reason it gets hot is because the fan is what removes the heat from the coil and if the fan isn't running there is nothing to cool it off so to speak.

Ac compressor will not start


Hello, sounds like a faulty capacitor. Check the capacitor to see if it is puffed up at the terminals. It will be located inside the outside unit and looks like like a can that is oval or round.

Replace the capacitor inside the control panel on the outside unit. The top of the capacitor may be puffed up.
The fan motor may also be going bad. Change the capacitor first. It will have to be changed anyway if the motor is bad.

Outside fan does not spin and a loud screeching sound coming from


Hey there, sounds like the bearings seized in your fan motor. You need to replace the fan motor. If the compressor runs without the fan, th pressures build up and if they reach an extreme point, the compressor will bypass internally, creating a loud sound as the high pressure is released to the low pressure side. I would turn the thermostat on and stand by the outdoor unit as it start. Leave the disconnect on the wall readily available so you can quickly turn it off. If the compressor sounds ok when it starts up and runs for a couple seconds, turn it off right away and replace the fan motor and you should be good to go. If the compressor sounds bad or real noisy immediately at start up, the fan motor not working killed your compreesor. You would need a motor and compressor, might as well replace the unit at this point if you are paying to have it done. Let me know if you need anything else

Weather King Heat Pump


Hey kellyrepp -- Three things to check quickly, so many things can be wrong, but i will try to help with the info you gave me.

The first sounds like your electric aux heat is not wired in or not working correctly , this should kick in when the heat pump cannot keep up with desired set temperature. For sure thats a problem

The second thing i would check is that the compressor for that unit is running. It should sound exactly like the one for the upstairs, the fan noise should be like a whrrrr , and the compressor should be a semi loud hummm.

Third feel the pipes on the outside unit that are on the outside of the unit (the unit for the second floor) Let the unit run for 5 minuites. Now check that the first floor unit pipes are the same tempereture. They are about 110 degrees or so, depending on the outside temperatur , be carefull not to burn yourself. If the lower unit is colder , the two most prominent problems would be #1 the compressor is not running #2 Low on freon.

Hope that helps

FANS ARE WORKING BUT THE AIR IS NOT COLD


That was real deep diagnoses I'm betting the outside unit is the problem. check the outside for240-volts to the contactor if not backtrack for the lost voltages and remove the outside cover to check the little silver can (capacitor) for swollen at the top terminials, due to power surge.
