← TechnologyWhich outcome occurs when differential thermal expansion compromises a bimetallic thermostat?
A)System temperature oscillates erratically✓
B)Refrigerant leakage increases drastically
C)Compressor operates continuously at maximum
D)Evaporator's defrost cycle triggers repeatedly
💡 Explanation
The thermostat relies on *differential expansion*, therefore, weakened bond oscillates because the metals no longer expand predictably. The result is that the temperature oscillates rather than thermostat maintaining stable operation; because leakage, maximum compressions or defrost are separate failures.
