Hello, Kirk. It sounds like you may have the A/C on energy saver mode, which the fan will continue to run for 1 minute after the compressor shuts off. The fan then cycles on for 20 seconds at 10-minute intervals until the room temperature is above the set temperature, at which time the compressor turns
back on. If you don't want it to cycle on and off so often, try using cool mode instead. ~ Brandi
