Upon inspection, the vent motor was found to be malfunctioning, causing inadequate airflow throughout the system. I began by carefully disassembling the vent housing to access the motor. After identifying the faulty motor, I replaced it with a high-quality, energy-efficient unit. I ensured all connections were secure and tested the new motor to confirm proper operation. The airflow was restored, and the system was running smoothly. I reassembled the vent housing and conducted a thorough inspection to ensure everything was in working order. The customer was pleased with the improved performance and efficiency of their ventilation system.
