OT: HVAC AC Pros

[NikkiSixx]

ac doesn't come on, and internal house blower motor does not turn on, in the on position, turn it back to auto.

replaced capacitor with another one (not the same, but all I could find, with 45/5 for dual use)

Turn all breakers back on (none had been tripped) and nothing.

Replaced battery in thermostat, ended up junking the thermostat and buying a new one.. put that in, with new batteries, and nothing. Thermostat calling for cool.

Order a new blower motor assembly.. while waiting for it to arrive, it's been 4 + days, I am running a portable AC unit in the interim, when all of a sudden, the ac, which has been in the on position and calling for cool for 4 days, all of a sudden starts working.

Thoughts?

You fixed it

You fixed it

as it sat for 4 days? I don't think so.. yes, I'm grateful it started working, but now I don't trust it, why did it fail and sit there for 4 days laughing at me.

Was it running continuously for a while before it quit? Did you notice if any of the condensate lines were iced up?

It could be SO many different stupid little things. Do you own a multimeter? Not a Menards meter.. I’m talking a legit meter.

This is probably it...

There is also a chance that the fan is dying.

HVAC...more like HVAG! Right, Right?

Keep an eye on it. If it stops working again, you may very well have a refrigerant leak in the evaporator coil. It could have frozen the coil and just took awhile to dethaw.
