Warranty less than one year No low-voltage reaching outdoor condensing unit on the orange reversing valve wire. Found a splice inside the brick where all of the wires were not spliced only five of the eight were spliced/connected. Used Brown low-voltage wire from the air handler to the outdoor unit for the reversing valve and system is now operating properly. Not able to complete splice inside the wall without removing brick or sheet rock from the other side. Both the green and orange wires are not complete between the outdoor and attic space. Tested system in both heating and cooling system is operating properly at this time.
