0 The trouble code for this furnace is trouble code four. Which indicates that a primary or auxiliary limit switch contact did not close after the inducer was energized. This could be caused by dirty filter, improperly sized duct system, incorrect blower speed setting, incorrect firing rate or faulty blower motor. Thanks for any replies or notifications.
