auxilary fan acting up

[Tony Hoffman]

Robby,

As Phil mentioned, this sounds like normal opperation, unless it's super
short cycles. Should cycle for about 15 sec, IIRC, then off, then on again
whenever the temp switch is triggered.

The AC runs the fan on low speed, till the temp switch overrides it. Then
it will run on high speed till cooled enough, then back down to low speed.
Unfortunately, living here in TX, my A/C gets used all the time :(
