The compressor has to be replaced if the bearings are bad in the compressor. Replace the condenser fan motor if the fan motor bearings are bad.

Hi,
No you can not use a R-410 air handler with a R-22 condenser unit...the exspansion devices are different as the properties of the refrigerants are enough different that they are not interchangable...
Really your only choice is to replace the whole unit as it sounds like the exspansion valve or the orfice is partially clogged and it makes you constantly freeze up....
There are some things you could do to make it work at reduced capacity but it is way beyond what I could tell you through a computer...

Could be the run capacitor is bad. Usually they bulge at the top where the connections are, but sometimes they are bad but appear to be fine physically. You would need a multimeter that reads microfarads to see if yours if good.Below is a link to the part in question. Yours should be rated at 50/5 mfd, 370 or 440 volts.50/5 MFD 440 Volt Round Dual Run Capacitor

AirConditioner Trouble - Review the Possibilities

Hello
There are a few things here that could be wrong.
1 Fan motor start capacitor is bad.Silver battery looking device on side of fan.Remove and replace with a new one.

2 Contactor for fan motor is pitted or burnt .If this is the case you will need a new contactor.

3 Fan motor is bad.Check top two before assuming this.
Check all fuses and circut breakers also.

Generally, the 40 amp circuit breaker can be found in your home's circuit breaker panel. In addition, there is a fuse-able cut off switch in a metal weather proof box, outside the house, adjacent to the compressor.

Hope this helps you find it. Thanks for choosing FixYa.

1/4 HP? Expect somewhere between $100 to $150. Read off other specs for the motor and call a vendor.

what doesn't work? the condenser the fan the compressor ? need more details

He should be charging like 1250 for that compressor job 1600 is a little much. Replace the filter drier and install the compressor and charge with freon. the compressor is like 500 to 600 dollars he is charging a lot of labor.

Goodman units are known to have problems with both the contactor - relay and the dual capacitors so that is a probable.

What we use is compressed air, either nitrogen and fittings or we use a small CO2 gun that you can pick up at local supply houses and some home improvement stores. You may have to cut into the condensate drain at the coil to blow through. It should be 3/4 in. PVC, and hopefully not copper since that would have to be soldered back. Some systems have a blow out somewhere on the drain line which helps. The only other problem would be the drain pan under the coil is also clogged, then you would have to open the coil case and try to unclog it from inside. Any kind of compressed air with some kind of fitting that seals the line when you blow through will work great. Hope this helps and good luck!

Hi,
You can try to get some light motor oil around the shaft and see if it will work into the bearing... usually the top bearing is the one to go bad...
Sometimes there will be an oil cup , but not on most motors anymore...

if the oil does not work then the motor will have to be replaced..

That depends upon the operating environment of the a/c system.The high side is directly related to the outside temperature and the low side depends upon the indoor temp, air flow across the evaporator coil, the relative indoor humidity and the static pressures of the duct system. There really is no rule of thumb to go by here but if all is operating properly then you should see something like this:

At 80° F the high should read from 277 psi to 295 psi with a clean condenser coil and the low will be about 116 psi to 130 psi or so if the blower and inside coil are functioning properly and the house temp is not too high or low.

*CAUTION*
If you are working with the high pressure of R410A refrigerant, also known by the trade name of Puron, then please take precautions to avoid accidental exposure of the face, eyes and exposed skin of the refrigerant and the POE oil it contains. Severe frostbite, lung damage and loss of eyesight may occur if exposure to raw refrigerant is experienced. Please consider calling a professional in your area to work on any refrigerant system.
