Signs of bad refrigeration reed valves
WebThe compressor has reed valves to control the entrance and exit of refrigerant gas during the pumping operation. These must be firmly seated. An improperly seated intake reed valve can result in gas leaking back into the low side during the compression stroke, raising the low side pressure and impairing the cooling effect.
