Our refrigerator, Amana ASD262RHRW, was working fine until something blocked the freezer door open and it froze up completely. The evaporator was frozen solid and even the damper had ice in it. I defrosted it a little and some ice fell in from the freezer side into the damper area. Since it was defroster it worked for about one week then was frozen solid again. This time I defrosted it completely and a week later it was frozen again. I checked the resistance of the defrost heater and it was about 30 ohms so I replaced the defrost time. The compressor and the evaporator fan cycle off and on but the defrost heater does not kick in. Is there any chance that the defrost thermostat is not working (is stuck open)? I thought it the defrost thermostat was open it would never cool down and it does that great until it freezes up and I have to defrost it. Could the ice that fell in the damper between the compartments have damaged the main circuit board, I have no idea where it is located? Thanks in advance.
