A/C is working fine but will not automatically switch over to recirculate (max cool) on warmest day like it is suppose to.

They don't AUTOMATICALLY switch. You have a button to request that.

Seems like actuator is working fine. Unfortunately my climate control panel does not have a max a/c switch. The owners manual says it switches to max (recirculate inside air)automatically when necessary. Any other ideas?
