At abnormal conditions, what should the evaporator fan motor amps be?

The correct answer regarding the evaporator fan motor amps under abnormal conditions is 8.4 AMPS. This value typically reflects the expected operational range for many industrial refrigeration applications under stressed conditions, such as increased load or higher temperatures.

During abnormal conditions, the evaporator fan may need to work harder to maintain airflow across the evaporator coils, which can result in increased amperage. The motor draws more current to compensate for factors like a dirty coil, restricted airflow, or higher refrigerant temperatures, which all lead to a higher demand on the system.

Understanding the normal operating range for motors is critical for diagnosing issues and ensuring the system runs efficiently. If the amperage exceeds this value, it may indicate a problem within the system, such as a failing motor, electrical issues, or other operational inefficiencies that need to be addressed to maintain proper functioning and avoid potential damage to the equipment.
