if the unit performs as it previously did, you may have a restricted capillary line or condenser or kinked
line. Find the point of restriction and correct it.
A restriction reduces the flow rate of the refrigerant and consequently reduces the rate of heat
removal. Complete restriction may be caused by moisture, solid contaminants in the system, or a
poorly soldered joint.
Moisture freezes at the evaporator inlet end of the capillary tube or solid contaminants collect in the
drier/filter. The wattage drops because the compressor is not circulating the usual amount of
refrigerant.
