Specific System Condition - Compressor At Maximum Displacement

Specific System Condition - Compressor At Maximum Displacement:





KEY: 1. LOWER THAN NORMAL SUCTION PRESSURE AND OUTLET TEMPERATURE AT LOWER AMBIENTS.
2. HIGHER THAN NORMAL DISCHARGE PRESSURES.


THEN: Compressor may be at maximum displacement.
^ This condition will be most noticeable at low ambients.
^ Confirm by touching the suction and discharge pipes at the compressor. Suction pipe will be very cold and discharge pipe will be hot.
^ This condition could generate an intermittent cooling complaint along with reduced air flow because of evaporator freeze up at lower ambient air temperatures.
^ Replace compressor.
^ After repair return to diagnostic flow chart.
