What can occur if a high side float is not functioning properly?

• A. The system may overshoot on pressure
• B. The evaporator may flood
• C. The compressor may not operate
• D. The refrigerant may leak

Answer: (B)

When a high side float is not functioning properly, it can lead to the evaporator flooding. The high side float plays a critical role in regulating the level of refrigerant within the system. It helps maintain the proper level of refrigerant in the evaporator to ensure efficient heat exchange. If the float malfunctions, it may allow too much refrigerant to enter the evaporator, leading to flooding. This flooding can cause several issues, including a decrease in the system's efficiency, potential damage to the compressor, and operational failures. In contrast, the other potential outcomes listed do not primarily stem from issues with the high side float. While overshooting on pressure can occur due to a variety of other factors in the system, it is not directly a consequence of a malfunctioning float. Similarly, while the compressor may not operate properly in certain situations, a high side float issue specifically leads to flooding rather than outright compressor failure. Lastly, refrigerant leakage generally corresponds with physical damage or improper seals in the system rather than float operation, making it less relevant in this context. Therefore, the correct answer focuses on the flooding of the evaporator as the immediate and direct consequence of a high side float failure.
