But before you reset the thermostat, let the compressor cool down for about 5 to 10 minutes before starting the air conditioner again. Pressure will build up in the compressor causing it to shut down the cooling unit. Trying to go from, for sake of argument, 90 degree interior temperature to a 70-degree interior temperature is too great a gap for the unit to function properly.
