Abstract
A control circuit for a room air conditioner includes two temperature sensing devices and an associated switch network which operate to de-energize the evaporator fan upon de-energization of the compressor but, as the temperature of the room air subsequently rises, cause the evaporator fan to be energized prior to re-energization of the compressor. The evaporator housing and temperature sensing devices are arranged such that during operation of the evaporator fan one of the devices senses the temperature of air entering the evaporator while the other senses the temperature of air leaving the evaporator, but during periods when the evaporator fan is off the device which formerly sensed the temperature of air leaving the evaporator operates to sense the temperature of room air.
