Hello all, happy holidays!
I'm in south FL, and have a Rheem central A/C system ~3 years old with electric
coils in the air handler.
This AM, for the first time this year, I had occasion to turn on the heat. Set
'stat to "heat", fan was on "auto", house was 60
degrees and setpoint was 70, and... nothing. In particular, no fan (I can hear
the fan from where the thermostat is located).
Not wanting to set anything on fire, I shut it off after ~5 seconds. Switched
fan to "on", mode back to "heat", hot air comes out
So my question: when the thermostat calls for heat and the fan's set to "auto",
the fan is supposed to come on immediately, isn't
it? There isn't a time-delay relay in there or anything, right?
Just FYI it worked fine last year and nothing's changed since then. Really!
