The doors have heaters on the opening edge; that is, the edges that face each other in the center of the refrigerator. These small, 2-watt heating elements keep condensation from forming along the opening where cold air escapes when the doors are open. The heater is foamed into the door assembly, so the only way to replace the heater is to replace the entire door. |
To check the continuity of the door heater circuit, unplug the 6-pin connector at the top of the door hinge. Pins 2 and 3 have no connection. Pins 1 and 4 – Infinity (Brown and yellow) Pins 1 and 5 – Infinity (Brown and red) Pins 1 and 6 – 1.8 kohm (Brown and white) NC – No Connection |
