    Trane xv90 troubleshoot
    Can you tell me if I can reliably replace the existing but faulty CNT 03777 integrated furnace control with the next version (CNT 04985), or should I spend twice as much on the current version (CNT 05160)?
    Thanks

    Actually the 03777 is not replaced directly by the 05160 which is the newest version so I would use the CNT 04985 version which is a direct replacement for the CNT 03777 and save some money. They are all 2 stage heat boards but pay attention as to how they are exactly wired when you do the replacement. This is one of the reasons I do not care for Trane/AM Standard equipment. The price of the CNT 05160 is outrageous. Make sure all power to the unit is OFF and ground yourself to get rid of any static electric.
