When a refrigeration compressor is in the 'off' cycle, the thermal expansion valve will react in what way?

Correct Answer: Option A — it will continue to function as a result of the net balance of forces acting on the diaphragm

During the compressor off cycle, bulb temperature and corresponding pressure changes continue to exert force on the upper diaphragm, balancing against evaporator pressure and spring tension. The valve dynamically responds to these net forces until system pressures equalize.
