Customer said AC not shutting off, came to home and system was off, first started with AC dropped temperature in home to 73, let run turned thermostat to 76 and system shut off, cycled heat raised temperature to 80 burner came on let run until blower came on, lowered temperature in home burner shut off and blower ran to cool heat exchanger, customer said she was cooking a lot today and was hot so system probably kept cycling to cool off home. Everything is operational and working.
