"But apply some coil cleaner, and the amps came down."
You stupid mormun mother-fucker.
If you PISSED on the condenser the amps would come down.
You have to be a troll. No one can actually BE so fucking dumb.
Add another 10 lbs of refrigerant. I dont think you quite have enough
liquid in the system yet .Once you get liquid spewing back out of the
suction service port, you are getting close. After you straighten that
out, then you can go electrical hunting to iron out the rest of the
Thanks again for everyone's input. Tonite I just got home and tried to
fire it up again. It came on and worked for about 10 minutes. After
that, sounds of sputtering and banging started coming from the external
unit. It sounds like a car sputtering (with a loud backfire thrown in
every once in a while), as if the compressor was cutting in and out
The sputtering occurs in short bursts, like a quick flutter. Every once
in a while, it make a loud bank (as I've described in other posts, like
someone kicking the side of the unit).
Eventually, the compressor and the fan just stop.
At that point, I shut off the A/C at the thermostat and try it again.
Almost immediately started making the same sputtering as before.
I'm in the San Fran Bay Area. We generally only use the A/C a few times
a year on really hot (95+ days). But the past week has been 100+ with
Sat. reaching 112 and Sunday reaching 116, so the A/C techs are

Well, that alone could account for the high amps, as the unit is rated

If that didn't change the results, I think I would take a very close
look at any limit switches in the furnace- most of them will interupt
the LV which would cause all your symptoms- the furnace is designed to
kick the high speed blower on when the limit opens- I have seen many
limits fail to the point of a light tap causing them to open?close
with no temp fluctuation.When the LV drops out, the condensor no
longer has power to the contactor coil, thus it shuts down, the fan
kicks into high speed and stays there til the limit once again closes.
The loud banging and chattering sound like the connection is opening
and closing at a high rate of speed. A short in the LV wiring could
possibly cause some similar actions, but most furnaces today have
fuses in the circuit board that will not tolerate much of a short.
Thanks for that reply, Eric -- that's very useful information. I'll try
jumping the R and Y at the furnace and see if that makes a difference.
Beyond that, I mainly just want to pass on these ideas to the tech that
comes out to hopefully get him on the right path to fixing the problem.
Thanks again -
