Today I arrived and met with Ron. I verified Ron’s concern comfort control system currently alarmed error 14. I investigated and I found ignition failed due to furnace PCB System. Supervisor Daryl brought parts to me onsite and I installed the board and a new flame safety system. Afterwards I verified concern is no longer present, system fires right up no issues at all. Upon completion left the system in auto mode set for 74 heat and 78 cool, currently 74 inside.
