The equipment in this month’s troubleshooting situation is a split system that has only been in service for two years, but there is a lot of history: several service calls since the equipment was installed, and an on-going complaint from the customer that the system just doesn’t keep their manufactured home comfortable.
Several technicians have reported that they checked the refrigerant charge. One technician reported adjusting the OBD (Opposed Blade Damper) supply registers in an effort to achieve a better balance of airflow throughout the three bedrooms, living room, dining room, and kitchen. Another technician replaced the indoor blower motor with an exact OEM replacement motor and capacitor. None of the previous service calls solved the problem and the customer complaint that the house often seems “sticky”.
