A contactor for air conditioning unit includes a first magnetic coil, having a first set of contacts for the compressor; a second magnetic coil, having a second set of contacts for the fan motor; and a time delay device connected in series with either the first magnetic coil or the second magnetic coil. The contactor provides for independent control of the compressor and the fan motor. During the time period when the fan continues running and the compressor is switched off, the device equalizes the pressure difference between different portions of the air conditioning unit.
