This invention was made to eliminate the above-mentioned drawbacks of the conventional air conditioner control circuit, and replaces the three indicators with one light emitting diode that emits two colors, such as red and green. By displaying the information during operation, abnormal stop, and defrosting in three colors: green, red, and orange, which is a composite color of green and red, the display area can be made smaller and the number of parts can be reduced. This is the purpose. Hereinafter, the air conditioner control circuit according to the present invention will be explained in detail using the drawings.

In the air conditioner control circuit configured in this way,
When the operation switch is closed, the relay radar changeover switch 11
.. A power supply is connected to the control circuit // through the contact c+b of A, and at the same time the green light of the light emitting diode base 6b is connected through the resistor g.
Current flows through it and it lights up green. If the abnormality detection circuit is activated for some reason and the relayer is energized,
The b contact of the changeover switch lIA of this relay t opens, cutting off the power to the control circuit // and simultaneously extinguishing the green color Ab of the light emitting diode base. Further, when the a contact of the changeover switch A of the relay t is closed, a current flows through the diode t and the resistor 7 to the red light emitting diode 6 6a, thereby lighting up the red light. On the other hand, when the switch S is closed during normal operation, a signal is input to the control circuit // to defrost, or at the same time, the red 1-aVc of the light emitting diode is energized through the diode IO1 resistor. As the red color lights up, it is combined with the green color and becomes orange. Note that the diodes 9 and 10 are provided to prevent leakage from occurring through the temperature switch 3 in the event that an abnormality occurs while the temperature switch S is closed.
