Which outcome occurs when a refrigeration system's condenser fan fails in a high ambient temperature environment?

💡 Explanation

When the condenser fan fails, heat rejection from the refrigerant slows, raising the discharge pressure and temperature, which the compressor needs to work harder against and draws high current, leading to a motor thermal overload. Therefore motor overload results, rather than icing, lower pressure, or valve instability, which stem from other refrigeration malfunctions.
