PROBLEM TO BE SOLVED: To solve the problem that a user or service man cannot easily find a failure of a sensor measurement unit or sensor driving unit.SOLUTION: An air conditioner includes a sensor measurement unit detecting a temperature, a sensor driving unit changing a measurement direction of the sensor measurement unit, and mode switching means switching to a sensor check mode of confirming a failure of the sensor measurement unit or sensor driving unit. In the sensor check mode, it is determined that the measurement direction of the sensor measurement unit is changed to at least two directions, and a change amount of a detection value of the sensor measurement unit in each direction is a predetermined value or more.SELECTED DRAWING: Figure 9 |
