John T for Model Number rb215bssb I've replaced the relay, the sensors, main control board, and the defrost heater, which was noticeably bad. And still every couple of weeks, the fridge evaporator coil would ice over on the top half of the coil only. I use a hair dryer to melt the ice, and it would work fine for awhile, and then the fridge would start be lose temperature again. What else can I do or replace? Thanks.
