The remaining time on the control varies up and down when using Auto-Dry (Sensor Dry). The Auto-Dry system senses the humidity level in the drum by reading the amount of moisture as the garments touch the sensor, so it is normal to see an occasional jump in time up or down of 5 minutes during the beginning of the cycle.
As the cycle progresses, the actual time will become more accurate with a normal load. However, smaller loads with only a few items occasionally touching the sensor bars may still continue to display jumps in remaining time throughout the cycle. This is considered normal operation.
The moisture sensor can be cleaned with a small amount of rubbing alcohol on a clean cloth to remove any buildup of fabric softener on the metal bars.
If the dryer is not working properly, service will be required. To schedule a repair appointment for Haier branded appliances in the U.S., visit https://www.haierappliances.com/support/schedule-service or contact Haier Appliances at 1-877-337-3639.
