ABSTRACT:
A method for detecting the presence of a synthetic fabric load during an automatic drying cycle in an automatic dryer avoids premature termination of the automatic drying cycle and ensures that the synthetic fabric items are dried according to a user's desired dryness level. The presence of the synthetic fabric load is detected by determining a duration of a first heating cycle, determining a duration of a second heating cycle, and determining the presence of the synthetic fabric load based on the durations of the first and the second heating cycles.
