PROBLEM TO BE SOLVED: To provide a control device of an indoor opening combustor capable of warning and displaying to prompt to perform a ventilation in a room without displaying that equipment is abnormal even when a misfire occurs due to the deficiency of oxygen in the room. SOLUTION: This control device comprises a flame current detection means 4 for detecting the state of combustion by a flame current between a burner 1 and a flame rod 2, an ignition determination means 5 for determining ignition/ no-ignition according to signals from the flame current detection means 4, a display part 7 for displaying temperature information and abnormal states, a display control means 8 for controlling the display of the display part, and a timing means 9 for timing a time passed from fire extinguishment. The display control means 8 is formed so as to display an abnormality to notify that an ignition is failed on the display part 7 when the time passed from the fire extinguishment is out of a specified time when the ignition determination means 5 determines the state of ignition to be non-ignition and to warn and display to prompt the ventilation when the time is less than the specified time.
