If the condenser fan fails, what will likely happen in the system?

When the condenser fan fails, its primary role in dissipating heat from the refrigerant in the condenser is compromised. The condenser relies on airflow to effectively remove heat from the refrigerant as it passes through the coils. If the fan is not operating, the heat cannot escape efficiently, leading to an increase in the temperature of the refrigerant.

As the refrigerant temperature rises, the pressure in the condenser increases due to the relationship between temperature and pressure defined by the properties of gases. This condition can lead to elevated pressures throughout the refrigeration system as the refrigerant continues to be circulated by the compressor, which is still operating normally.

Excessive pressure in the system can lead to various operational issues and can even trigger safety mechanisms designed to protect the system from damage. Therefore, understanding that the failure of the condenser fan will disrupt the heat exchange process and elevate system pressure is crucial in refrigeration concepts.
