An automatic control for an air conditioner having a compressor motor and a fan motor and a method for its operation are provided. While the control operates both motors to cool an enclosed space, a temperature indicative of the air temperature in the space is sensed and compared with a first preselected temperature value. When the sensed temperature is no longer greater than the preselected temperature, operation of the compressor motor is terminated. Thereafter the fan motor is operated for a first preselected time period. During the first time period, a currently sensed temperature indicative of the air temperature in the space is compared with a second preselected temperature value. When the sensed temperature is no longer less than the second preselected temperature during the first time period, operation of the compressor motor is resumed and the process described above with respect to cooling the space is repeated. Upon an expiration of the first time period without exceeding the second preselected temperature, operation of the fan motor is terminated. Thereafter a second preselected time period is initiated. After expiration of the second time period, a currently sensed temperature indicative of the air temperature in the space is compared with a third predetermined temperature value during a third predetermined time period. When the sensed temperature is no longer less than the third preselected temperature during the third time period, operation of the fan motor is resumed, the first time period is restarted and the operation described above with respect to the first time period is repeated. Upon an expiration of the third time period without exceeding the third preselected temperature, the second time period is restarted and the operation described above with respect to the second time period is repeated. 17
