The freezer in my LG French Door refrigerator began thawing the other day. I discovered that the compressor was running but the evaporator fan was not on. In the process of removing the evaporator fan, I inadvertently discovered that the fan works if the freezer sensor is NOT connected. As soon as I reconnect the freezer sensor the fan stops again. Even though the sensor tested good with an ohmmeter, I bought a replacement anyway (they're cheap). The fan still does not turn when the sensor is connected. I have been running the refrigerator for five days now without the sensor and it is very cold. Unfortunately, I have an error message indicating there is no sensor connected
(makes sense), and my ice and water dispenser do not operate as a result. Is this a motherboard problem or something else??
