Harper College 108-248 procedures 8. Residential freezers are air-cooled and may have two fans provided with forced draft refrigerators, one for the condensers and one for the condenser fan motors. What type of motors are typically used in household condenser fan motors? What will result if the condenser air flow is blocked? What happens to the temperature of the refrigerant in the compressor discharge line when the head pressure increases? Because most condenser fan motors are located at the bottom of the appliance, what tends to accumulate on the condenser creating airflow restriction? List the three primary functions of the condenser coil.
