Troubleshoot Why A Refrigerator Is Too Cold With These 4 – Steps

Step-1. Air Inlet Damper

  1. Air Inlet Damper – If your refrigerator is getting too cold, you might have noticed some items in the fridge compartment are frozen.  The air inlet damper, also known as the air damper, baffle or diffuser is used to balance the cold air flow from the evaporator housing to the refrigerators fresh food holding section, on most models.  The inlet damper is made of plastic, with louvers like window blinds, and is usually located on the interior wall of the fresh food compartment toward the bottom of the fridge.  The control knob for the damper is located next to the fridges cold control knob, it might have freezer printed above or below it, it will be the knob (without) the off position option.  Is the knob set on too cold of a position? if so move the knob a little bit to the warmer position.  You should be able to open and close the damper by adjusting the damper control knob.  If the damper diffuser is broken it will let too much cold air into the refrigerator, freezing the fresh food.  The optimum temperature inside of a refrigerator for safe food storage is between 34 to 40 degrees fahrenheit.   If the temperature is any colder than 34 degrees F food will start to freeze, if the temperature is any warmer than 40 degrees F the food will start to spoil.  You will need a refrigerator thermometer to adjust and set the fridges temperature correctly, you can purchase a refrigerator thermometer fairly cheap from almost any hardware store.  The factory suggests that the air inlet damper knobs indicator dial be set at the mid range, strait up 12 o’clock position.

Step-2. Cold Control Or Temperature Control

You will need to check the cold control knob/dial located in the refrigerator cabinet, is it set at too cold of a position? if so, try turning the dial to a warmer position.  NOTE – The refrigerator cold control dial should only be turned about 1/8 of a turn in a 24 hour period.  You will need a refrigerator thermometer to adjust and set the refrigerators temperature correctly, you can purchase a refrigerator thermometer reasonably cheap from almost any hardware store.  The factory suggested setting for the temperature control is mid range, this means that the indicator on the dial/knob should point in the 12 o’clock position.  The optimum temperature inside of a refrigerator should be between 34 to 40 degrees fahrenheit for safe food storage.   If the temperature is any colder than 34 degrees F food will freeze, any warmer than 40 degrees F food will start to spoil quickly.  Adjust the cold control knob 1/8 of a turn every 24 hours, and take notes of how much colder the fridge has become, and repeat the process until you hit the optimum temperature range, between 34 and 40 degrees fahrenheit.

Step-3. Thermistor Or Temperature Sensor

If your refrigerator is equipped with an electronic control board the temperature is going to be controlled by a thermistor.  This part is usually located near the fridges air inlet, the thermistor senses the temperature and relays it back to the refrigerator electronic control board.  The control board will then monitor the temperature and will make the necessary adjustments to the cold air inlet damper as they are needed.  The temperature sensor could be faulty if it’s too cold in the fridge compartment.

Step-4. Electronic Control Board

A faulty electronic refrigerator control board could be the reason why the fridge is too cold.  The control board is used to control a multitude of a refrigerators parts and functions.  The control board is a very difficult part to test.  You can visually inspect the fridges control board for burnt spots, melted relays, solder joints or any other obvious signs of electrical damage and replace the board if you see any of the mentioned damage.  Electronic control boards aren’t cheap, some control boards can be pretty pricy.  Only after troubleshooting all of the other refrigerators components that could be at fault for the reason your refrigerator is getting too cold, should you suspect the electronic control board to be the culprit.
