Abstract: PURPOSE:To allow a user to easily and surely repair an abnormal state by a method wherein when component members of a combustion apparatus are out of order, countermeasures are indicated on an operation board of a remote controller, etc. CONSTITUTION:When receiving a signal from an abnormal state detector 1b, a microcomputer 1 checks whether or not a fan is out of order and it occurs for the first time. When it is the first time, an output is given to an I/O 1a to turn on an LED 3a. When a faucet is opened once and closed again, the fan is stopped and the abnormality is removed. When it is the second abnormality, an output is given to the I/O 1a to turn on an LED 3b. And, when an operating switch is reset, the fan is stopped. When it is the third time or more, an output is given to the I/O 1a to turn on an LED 3c. Then, when the abnormality is not removed even though a power source is reset, request for repairing is informed by a message C. On the other hand, when deciding that it is not caused by failure of the fan, the microcomputer 1 checks a water solenoid valve for abnormality, and when the water solenoid valve is not opened, preventing water from being supplied, an output is given to the I/O 1a to turn on the LED 3b. When the water solenoid valve is not in abnormal state, an another component member 2 is checked.
