The GE 
                                JVM6175DFWW is part of the
                                Microwave Ovens test program at
                                Consumer Reports.  In our lab tests, Over-the-Range Microwave Ovens
                                models like the JVM6175DFWW are rated on multiple criteria, such as those
                                listed below.
                            
                                                        
                                Heating evenness:
                                A high score means the microwave heats food evenly without hot or cold spots. A top-scoring model warms center and edges alike, helping heat foods like leftovers evenly.
                            
                                                        
                                Defrosting evenness:
                                A high score means the microwave's automatic-defrost program thaws food evenly without partially cooking or leaving icy spots (we test using frozen ground beef). A top-scoring model thaws meat uniformly and nearly completely, with some models fully defrosting the food.
                            
                                                        
                                Speed of heating:
                                A high score means the microwave heats quickly. A top-scoring model shortens cooking and reheating time.
