Question about LG Heat cool Window Air Conditioner

AC Compressor My A/C Compressor is not starting. My Mechanic says he has to flush nitrogen into it, remove the gas inside and then try starting it.He did this and then topped up the gas, Now he is charging me heavily for the topped up Gas. Is it right what he did to start the compressor? My compressor was fully loaded with gas prior to the service.

Re: AC Compressor

Does not sound right to me.My guess after doing what every he was doing he probably installed a start capacitor or repaired a burnt wrie, got the compressor running and charged for a lot of guess work. Just guessing.

have the ac check for gas leakage and proper amount of gas. Is the compressor clutch working and driving the compressor.. What you have is the fan is just circulating cabin air at ambient temperature. Best take it to an ac mechanic for full problem check.

Helo I am muhammad iqbal i fill gas in unit after few mints its chowked i fix the new gas filter in out door unit and clean all gas systam out door unit also have problam

Dear Iqbal! Remove filter drier again. And flush out with Nitrogen. Now, Braze filter drier and then vacuum minimum 1 hour. Close valves and break the vacuum by charging little freon, say 80psi in ideal.
Run the unit and start gas charging till return good and back pressure 60 psi @ 98 degree ambient.
Now, the unit will survive for longer period further, provided servicing the unit periodically. Helpful?

Hello Sometimes there is a SCREEN in the liquid line just b4 the piston in the tube.You had a SEVERE burnout the filter driers are shot from doing there job even with the short run time.Also you could try pulling the piston out and blow out the cap tubes in the evap.Close the suction service valve and pressurize the pipe and let it blow out the piston holder ot help clear those tiny tubes.Use a OVERSIZE liquid drier this time,Get a 10 ton drier or better.

Frigidaire FAS296N2A starting capacitor

If it has a start capacitor the papper hole in the top of the start capacitor
will be broken if the capacitor was shorted I would have the run capacitor frist But if there is not a burnt wire then the compressor may be bad. You can try a hard start kit that pulgs on the two terminals of the run cap to see if the compressor will start but you will need a amp meter to tell if the compressor will continue to run

AC is just blowing air. The compressor doesn't kick on.

no freon.. pressure test w/ nitrogen. 8000 btus is now junk. Spend the money on new unit otherwise find the leak. It leaked out thats why the compressor will never go on. Once you add freon she'll turn on...same as car.

Dont buy that name brand again. best of luck to you

When your compressor on heatpump burns out how do you clean the system before installing new compressor

Flush the system with Nitrogen. Then R-11. Then install low side and high side filter driers. Then replace the low side filter drier after 2 weeks running time.

2 ton sanyo suction pressure erratic

Your suction pressure is erratic, your max. pressure is to much high. You did not measure your unit current reading liquid line press. to complete the data. But the problem of your unit is not the compressor its the system. Try to reprocess the system flush the unit with nitrogen, isolate the capillary tube and flush it with nitrogen to insure that no restriction.
