ESCO Air Conditioning Practice Exam

Question: 1 / 400

What symptoms will a faulty condenser fan motor cause in an air conditioning system?

High suction pressure and high discharge pressure

A faulty condenser fan motor can cause high suction pressure and high discharge pressure in an air conditioning system. This is because the fan motor plays a crucial role in moving air across the condenser coils, which helps to dissipate heat from the system. Without proper airflow, the condenser coils cannot effectively remove heat, causing high pressures on both the suction and discharge sides of the system. This can lead to a decrease in overall cooling efficiency and potentially result in system malfunction. The other options are incorrect as they describe either low suction pressure, which is not caused by a faulty fan motor, or low discharge pressure, which would not occur simultaneously with high suction pressure due to an issue with the fan motor.
