The garage refrigerator heater kit from AppliancePartsPros.com worked like a charm. The instructions were easy to follow, and the installation only took about 10 minutes start to finish. Since I installed the kit we have had temperatures in the low teens to mid twenties, with garage temps from 35 to 40 degrees. The freezer temp has maintained at around zero degrees.
Customer service was very helpful to answer my question about the applicability of this part for my model number. The order was processed the same day, and the part arrived as promised.
