i recently had to have the condensing unit changed out, in my home.
the unit is a 3 ton 13 seer amana condenser. i don't know what the
evaporator brand is, but it's about a 10 seer with the same tonnage.
The amana unit is only about 2 months old, but when it runs, sometimes
it squeals, sometimes the fan does not come on, and sometimes it acts
like it's straining to compress the refrigerant. it acted fine, for
about a month, then, one day, i walked outside, the compressor was
running, but the cooling fan was off, and the compressor was
squealing. ever since then, it exhibits the signs above. i had an a/c
tech come out and look at the unit. he advised that the condenser is
too inefficient for the evaporator, and the refrigerant is reaching
the compressor in a liquid state.

now, i know the basics of how refrigeration works, but i'm no expert,
although, i'm a quick study.i do build computers, so i know how to
read a wiring schematic. i noticed that the condenser has a 2 speed
fan, so i had him buy pass the low speed, to make sure that it wasn't
the speed switch. so far, i have not noticed the compressor running
with the fan off, but it has only been a day.

does the guy's theory about liquid refrigerant reaching the compressor
hold "liquid refrigerant" he didn't take any pressure readings from
the lines.


You have problems!
