Air-conditioning and heat strips on at the same time, found that the thermostat wire has been chewed up by some kind of animal, bare wires touching, disconnected the white wire so at this time only the AC will run, there is a possibility that has the wire deteriorates the AC could run and never shut off if that were to happen turn off the breaker to the machine, Will need a new thermostat wire customer has a home warranty service that is going to come out and repair it, Thank You
