Don for Model Number SZD27MW As a follow up to my question as to the cause of the freezer not holding temperature while the refrigerator is maintaing 34 degrees F, I had a repairman check it out. The coils are clean and the fans are working. The repairman claims the compressor isrunning hot and is heading for total failure. Since this is a R12 system, he recommends replacing the refrigerator. He also claims the freezer control is not the problem. Is his diagnosis accurate or should I spend the $55 for a freezer control?
Answer Don, At this point, It sounds more like an air flow issue, or a door seal problem. Your refrigerator is an older unit, and does operate using R12 refrigerant. But you're maintaining temperature in the refrigerator compartment. If you had a compressor issue, the temperatures in both compartments would be affected, not just one. Check and make sure the both door seals are in contact with the front flange of the cabinet, when the doors are closed. Check and make sure, there are no articles hanging over the sides or back of the shelves, restricting the air flow, and check the air return tunnel (behind the crispers) on the left side wall,as well.You could have a "sticky" freezer control contact, but you may want to reset the refrigerator control a setting or two warmer, first. Then check for an intermittent issue in the evaporator fan WPC8891605 or defrost thermostat WPC8972006. There's no accurate way to test a compressor for age or efficiency, without conducting a wattage, amperage, and voltage tests with meters, and or guages on the sealed system, even then there are no guarantees.
