Dometic Refrigerator Not Keeping Cold

One thing you may want to try before spending any money is moving the temperature sensor that hangs by a clip inside the refrigerator. Its purpose is to sense the temp in the fridge and turn on or turn off the cooling unit at the appropriate times (similar to the thermostat in a home). Normally, the warmest part of the fridge is going to be near the top. Coolest part is near the bottom. A friend of mine was experiencing higher than normal temps. We found that the sensor had been knocked loose from its normal position on the metal cooling fins at the top of the reefer cabinet. It was hanging down by the wires at a much lower location than normal in the reefer cabinet and therefore turning off the cooling unit prematurely. We clipped the sensor back up top on the far right side of the cooling fins. Unit seems to be working fine since then.
