Why is my freezer not defrosting?
I have a Kenmore/Whirlpool refrigerator/freezer (bottom-mount freezer) - model # 596.75232404. The freezer is frosting over and doesn’t defrost. I replaced the defrost thermostat and heating element. Even when I put the appliance into the Forced Defrost mode (both Short & Long cycle), the freezer does not defrost. Does that mean that the problem is the main control board?
