Expansion Valve: Testing and Inspection

Fig. 8 Expansion Valve Diagnosis Chart

Faulty expansion valves will be indicated by low suction and discharge pressures on the manifold gauge set.  In most cases the power element fails and
the valve closes.  Occasionally the inlet screen becomes clogged with contamination or desicant beads loose in the system.
