Fan only control
Last night I decided to use the bedroom HVAC for air circulation. When turned to fan something comes on but no air flow. My suspicion is the fan and compressor control wires are switched. Was wondering if anyone has had a similar issue.
As an aside , once this summer I thought the evap was iced up because unit was running but no air flow. Now I'm thinking it had reached temp and instead of fan running to dry it the compressor was running.
Thanks , CharlieVickie & Charlie

Update - This one is repaired. As suspected wires were crossed. The compressor control (yellow) and high speed fan control (green) wires were swapped in the thermostat connector.

Gotta love it when it is an easier fix. Did you do it yourself?

I did. Going thru the switch positions I was pretty sure of the issue. Removed lower cover & wiring on control relay was correct by color , but checking 12 volt revealed signal coming up wrong wire. Pulled t-stat and found issue. The t-stat base actually has the color coding on the back side.

Sometimes I think it's a curse to be so handy.
