The invention discloses an automobile air conditioner PTC electric heater dry burning protection control system which comprises an automobile air conditioner controller, the I/O input end of the automobile air conditioner controller is connected with a PTC electric heater, and a PTC temperature sensor is arranged on the surface of the PTC electric heater. The automobile air conditioner controller is electrically connected with the PTC high-voltage contactor, the cold and warm air door actuator, the air blower speed regulation module, the mode air door actuator, the circulating air door actuator and the instrument panel alarm. The dry burning protection control method for the PTC electric heater has the advantages of being good in feasibility, higher in efficiency, processized in operation and capable of shortening the response time of the controller, and the problems that an existing dry burning protection method is long in response time, poor in effect and high in cost are solved.
