A:Answer All our current GE Appliances refrigerators use a reciprocating compressor. None of our refrigerators use linear (inverter) compressors. -- This model features a one-year limited warranty which covers any part of the refrigerator which fails due to a defect in materials or workmanship. Since it is a GE Profile model refrigerator it also has a five-year warranty on any part of the sealed refrigerating system (the compressor, condenser, evaporator and all connecting tubing) which fails due to a defect in materials or workmanship. For more information, see page 46 of the Owner’s Manual, which can be viewed at the bottom of the Features tab on the PGE29BYTFS Best Buy product page.
