Re: [DML] A/C problem: compressor is not cycling

I agree that everything must work correctly including the compressor
and you have to have the right amount of refrigerent and you have to
get all of the air out. You also have to have clean coils and the
orifice tube can't be plugged up etc. Assuming you have all of that
and the pressures are OK I see no reason the pressure switch can't be
adjusted. I also agree that you should not adjust the presssure switch
to compensate for any deficences but from what I have heard so far the
only "problem" seems to be air in the system. Once he gets rid of the
air it should cycle but the switch may still need to be adjusted a
little. The most critical thing is to have the system complelty
evacuated and then accurately meter in the correct amount of R-12.
Besides, adjusting the switch is not so bad, not as bad as NOT
cycling. If you do not cycle you will overload the cooling fan circuit
and freeze the evap coil. I would rather see an incorrectly adjusted
but cycling system than a system that doesn't cycle.
