I turned on my AC few hours ago and set to blower to ON, as opposed to
AUTO. The temp hasn't reached the set point yet, so the AC has been
running since I turned it on.

I was down in the basement doing some stuff (unrelated to the AC) when
the blower stopped. Curious, I went upstairs to check the thermostat
and it was calling for AC and the blower was still set to ON.

I went back downstairs and after about 20 seconds the blower came back
on. I don't think it was off for more than a minute. This is the
second season with the AC and I don't recall this happening before,
but since it was off for less than a minute, who knows?

Any thoughts?


Blower motor may have a thermal protection device
(in the windings). If that is tripping (and then
resetting after cooling off), it's not a good sign.

The motor may need lube or the blower may be overloaded
from excess static pressure or running at too high a speed.
Have a peek at the filters too.
