1-7. Temperature sensing circuit
1) GR-L267, G267, P277
The circuits involving the freezer and refrigerator sensors control the temperature in both the freezer and the refrigerator.
The Icemaker sensor detects when ice is made. The defrost sensor determines both the need for defrosting and the
efficiency of the defrost operation. See the table below for voltages and checkpoints.
