My refrigerator coil has frozen over three times now.
I defrosted the ice two times and then on the third try I finally opened the drain to the evaporator with hot water and cleared it too but the fridge coil has frozen up again. The cooling seems to work fine until it freezes over.

Does anyone have a suggestion about what to do or what parts I should replace?

This indicates a defrost problem. One of three commonly occurring causes (or a combination of two or more) is: Defrost timer (or, as in the modern machines, a bad adaptive defrost circuit board) is bad; Defrost heater is burnt out or open in some way; Defrost thermostat is not working.
