Air conditioner fan control circuit

The invention provides an air conditioner fan control circuit. The air conditioner fan control circuit comprises a resistor R1 (1), a thermistor RT 1 (2), a resistor R2 (3), an NPN triode Q1 (3), a resistor R3 (5), an N-channel MOSFET Q3 (6), an electric heating wire OV 1 (7), a PNP triode Q2 (8), a resistor R4 (9), an N-channel MOSFET Q4 (10), a motor M1 (11), a capacitor C1 (12), a resistor R5 (13), a motor M2 (14) and a capacitor C2 (15). According to the air conditioner fan control circuit, when the temperature is low, the resistance of the thermistor RT 1 (2) increases, the NPN triode Q1(3) is turned on, the N-channel MOSFET Q3 (6) is turned on, the electric heating wire OV 1 (7) works, and the motor M2 (14) drives a fan to blow hot air outwards; and when the temperature is high, theresistance of the thermistor RT 1 (2) is reduced, the NPN triode Q2 (8) is turned on, the N-channel MOSFET Q4 (10) is turned on, the motor M1 (11) drives the fan to rotate to blow an ice tray into amachine at a low temperatur
