My upstairs air conditioning unit (Goodman) has had some strange behavior the last few nights. The fan is automatically shutting off once it has cooled to 73 degrees, even though the thermostat is set to cool to 70 degrees. The outside unit is still running, it's just the fan that shuts off. This happens whether it is set to auto or on.
I did go in my attic and shut the power down for a few minutes early this morning and that seemed to have corrected the problem (so far). I'm just trying to determine what could have caused this and what I should do about this. The fan would run once it went over 73 degrees again.

when running A/C you have two fans operating.the outdoor fan on top of the outdoor portion of the a/c and the indoor blower fan that blows cold air thru the house.I assume you are talking about the indoor fsn that stops running at 73 .if the indoor fan stops and the outdoor unit is still running your coil will begin to ice up.if its the outdoor fan that quits with yhe compresser still runnung then you will soon blow a fuse,or the compresser.call a service tech once it starts acting up again.
