Fritz, If your thermistor (air temp. sensor) is on an interior wall you might check to see if the discharge vent is dumping air on to the thermistor. you might be able to adjust vent, otherwise relocating the thermistor should improve the cycle time if everything else is correct. Give us the model number and production number so we can look up more info if you need it.
