We have some trble on a rooftop unit, and techs have been out 4 times. When I go to the stat and set mode to "off",unit continues to run and fan blows cold air. I throw the breaker for a minute or two, then the unit heats fine for a few days. Then problem returns, no error codes are displayed on the unit. Thanks
