A faulty condenser fan motor in an air-conditioning system will produce which symptoms?

A faulty condenser fan motor can lead to several issues within an air-conditioning system, particularly concerning pressure levels. When the condenser fan motor is not functioning properly, it fails to adequately cool the refrigerant as it passes through the condenser coil. This diminished cooling can cause the refrigerant to remain at high temperatures, which leads to high discharge pressure. Simultaneously, the lack of proper heat exchange can also result in elevated suction pressure as the refrigerant does not efficiently return to the compressor.

When both of these pressures are elevated, it can indicate that the system is experiencing a significant problem that could ultimately lead to compressor damage or system breakdown if not addressed. Therefore, the indication of high suction pressure and high discharge pressure effectively highlights the adverse impact of a faulty condenser fan motor on the air-conditioning system's operation.

In contrast, symptoms like irregular compressor cycling, high oil levels, or low suction pressure specifically point to other issues within the system rather than the specific consequences of a bad condenser fan motor.
