Question about Refrigerators
The freezer section has the only cooling coil. It sounds like it is blocked with frost and thus wont let the air circulate from freezer to refrigerator.
There is a defrost timer, (or board), a defrost heater, and a defrost safety thermostat. Any One of these or a combination of 2 can be your problem. If you have a energy efficient model that has electronic controls then you will have a board. The procedures for checking the circuit on a board vary by manufacturer of the board used and manufacturer of the appliance.
The defrost heater always has resistance and is attached to the freezer coil.
The defrost thermostat is also attached to the heater electrically, unless it is an electronic sensor type. Sensor types have a range of resistance that needs to be known to check and varies slightly with the temperature of the sensor.
If I haven't lost you here you maybe equipped with the life experiences that will allow you to do most of these checks. If its over your understanding I recommend you contact a reliable technician.
