Responding to a scheduled maintenance call, the technician arrived at the customer’s Sacramento home to perform a routine cleaning and operation check on their Whirlpool dryer. The technician began by vacuuming lint buildup from the exhaust vent before removing the front lint screen and trap to scrub away any residual debris. After wiping down the drum interior, the air ducts were swept clean to dislodge any lingering particulates. The technician then reassembled the dryer and initiated a timed air dry cycle to observe airflow and drying performance.
