Which outcome occurs when a refrigeration evaporator becomes excessively ice-covered due to moisture accumulation?

💡 Explanation

When an evaporator ices over, the insulative properties of ice inhibit heat transfer because ice reduces the effective surface area, preventing efficient heat absorption from the surroundings. Therefore, reduced heat transfer occurs, rather than increased motor current, refrigerant over-pressurization, or short-cycling, which involve different failure modes.
