Chosen Solution
I recently changed my control board and heater element because I was getting ice on the coils. After doing so I am still getting ice on the top coils not much but some. and the ice maker will not work. no water going into the tray.. I check the water dispenser and it has a strong flow and the water is cold. Not sure what to do next. I have a GE refrigerator Model: GSHF5KGXCCWW. your help is appreciated.
Get the cooling problem fixed first, the see about the ice maker. When this humid air passes over the cold evaporator coils, it condenses and freezes on the coils. If humid air is continually leaking into the freezer, theevaporator coils ice over too quickly, and the defrost cycle isn’t able to keep up. Most Frequent Causes for Freezer coils frozen Cause 1 Defrost Timer The defrost timer turns on the defrost heater several times throughout the day to melt any frost that may have accumulated on the freezer evaporator coils. If the defrost heater does not turn on, frost will continue to accumulate on the evaporator coils, and the coils will eventually frost over. In order for the defrost timer to turn on the defrost heater, the defrost timer must advance into the defrost cycle. If the defrost timer is not advancing properly, the defrost heater won’t turn on. To determine if the timer is defective, slowly turn the timer with a screwdriver or by hand. Turn the timer until it clicks. When the timer clicks, the compressor and fans will shut off. If the defrost thermostat and heater are working properly, the heater will turn on. If the heater turns on, this indicates that the timer is defective and must be replaced. Cause 2 Defrost Heater Assembly The defrost heater turns on several times throughout the day to melt away any frost that may have accumulated on the freezer evaporator coils. If the defrost heater does not turn on, frost will continue to accumulate on the evaporator coils, and the coils will eventually frost over. To determine if the defrost heater is at fault, use a multimeter to test the defrost heater for continuity. If the defrost heater does not have continuity, replace it. Cause 3 Defrost Thermostat The defrost heater turns on several times throughout the day to melt away any frost that may have accumulated on the freezer evaporator coils. Before the defrost heater turns on, the defrost thermostat must sense that the evaporator coils are cold enough. If the coils are cold enough, the defrost thermostat will allow the defrost heater to turn on. (Usually, the temperature of the coils must be below 30 degrees Fahrenheit.) If the thermostat is defective, the defrost heater won’t turn on, causing the evaporator coils to frost over. To determine if the defrost thermostat is at fault, use a multimeter to test the thermostat for continuity. If the defrost thermostat does not have continuity, replace it.
