Well, what doesn't kill us makes us more knowledgeable. I did know
enough to turn off all breakers including the one to the air handler
before monkeying with the outside unit so I wasn't in any danger.
Next I need to clean the internal coils. Just looked at 'em, they're
nasty. Obviously with as much suction as I'm getting plenty of air is
getting through but they definitely need cleaning.
Glad you got it running again. The run caps are usually cheap enough
that, even if you are not able to test, replacing them is worth a
shot. All you care about are the specs on it. Any shape will do.
Occasionally you have to fiddle around with the bracket to get it
bolted back to the chassis. Nice you found a supply house that was
helpful even though I suspect it was easy to tell you are a
homeowner. The hvac trade is extremely anti-diy.
You missed the breaker that the 24v transformer for the thermostat is
on. The air handler starts the outside unit with a 24v ac supply to
that contactor, aka relay. Unlike electrolytic capacitors these
capacitors are not polarized so there are no positive or negative
terminals. This is an ac circuit not dc. That board with the
flashing led is the defrost board. It's not involved in the operation
when you are using the unit in the cooling mode. Steady flashing
usually means it is ok. When there is something wrong it will flash a
signal where you can use the number of flashes to look up different
problems. There should be a couple pages of spec sheets in an
envelope inside the uinit and the flash code is often on those.
A few units will have a pressure switch that prevents the compressor
from starting up if the unit has lost the refrigerant. Don't know if
this one does or not, it's not all that common.
As the other poster said, the contactor is powered by the 24V from the
air handler inside your house. So even if you turned off the 240V, you
would still here the relay click.
Congrats on fixing the unit yourself despite the sarcastic remarks
some of these idiots made.
No, it doesn't because I've had background checks run on me
by the feds so I could get into places that you will never be
allowed to go. I also know how to avoid creating data trails
and I can guarantee that you can not find any information on
me. Don't waste your time trying. ROTFL
