General System Condition - High or Low Side Restrictions

KEY: TEMPERATURE DROP ACROSS RESTRICTION IN LINE OR COMPONENT.

THEN: Confirm condition by a thorough physical and visual inspection of all lines and components.

^ If the restriction is between the compressor and condenser, discharge pressure will be higher than normal.
^ Temperature will be much colder on the down stream side of the restriction. Also look for possible frost.
^ Replace the restricted part.
^ After repair return to diagnostic flow chart.
