LG Fridge Freezing Food – Common Causes

There are several reasons your LG fridge is freezing food. Below are some of the most common ones and how to fix them.

1. Faulty Thermistor

The thermistor observes the air temperature and then sends its reading to the fridge’s control board. The control board then uses the reading to regulate the refrigerant system.

If the thermistor is faulty, it may read the temperature incorrectly. The control board will work with the incorrect reading. This may result in the evaporator fan and compressor operating longer than they should.

You need to replace your thermistor if it is faulty; hence, you have to test it for fault. To test your thermistor, follow the procedures below.

How to Test LG Fridge Thermistor

To test your LG fridge thermistor, follow the steps below:

Step 1: Switch off the fridge and unplug it from the power socket to ensure safety.

Step 2: Open the fridge and drop down the control board which is usually located at the ceiling of the fridge.

Step 3: Take out the thermistor. And get a multimeter.

Step 4: Either let the thermistor warm to room temperature or put the thermistor in a glass of ice water.

Step 5: Use the multimeter to measure the thermistor’s resistance.

Step 6: Get the tech sheet for your fridge. This sheet contains a temperature resistance chart.

Step 7: Using this chart, determine if you have the proper reading of resistance for both the room and cold temperature.

Step 8: If the readings you get does not match what you have on the chart, then the thermistor needs to be replaced.

2. Malfunctioning Control Thermostat

Another common reason for food freezing in LG fridge is a malfunctioning control thermostat. The control thermostat regulates the fridge’s air temperature by periodically turning the refrigerant systems off and on.

When the control thermostat is malfunctioning, the compressor and evaporator fans may work overtime. This will cause the fridge to get too cold and freeze foods.

To test the control thermostat do the following:

i. While the fridge and compressor are running, turn the temperature from lowest to highest.

ii. Listen for a click while you do this. The click is an indication that the refrigerant system just went off.

iii. If you do not hear a click, then it’s likely that the control thermostat is malfunctioning.

If this is the case, then you need to change the control thermostat.

3. Broken Damper Control Assembly

The fridge stays cool because of the cold air that is usually supplied to it. And the damper supplies this cold air to the fridge.

It regulates the quantity of cold air that goes into the fridge by opening and closing. If the damper control assembly is broken, it may stay open and too much cold air will enter the fridge.

The check the damper control for faults, you have to inspect it visually. The damper control assembly may be at the back or top of your fridge, depending on your model. If broken, then you need to replace it.

How to Replace an LG Fridge Damper

To replace your LG fridge damper, follow the steps below:

i. To ensure safety, switch off the fridge and disconnect it from the power socket.

ii. Open the fridge and locate the damper assembly. Remove the bolts and screws holding the damper assembly in place.

iii. Check for and disconnect any wire harness attached to the damper control assembly and the fridge. Take out the assembly and bring it to a work table.

iv. Remove all wire harness connected to the damper and unmount from the assembly.

v. Get the new damper and put it in place. Reconnect all wire harnesses.

vi. Take the damper control assembly back to the fridge and screw it back in place.

vii. Switch on the fridge.

4. Defective Temperature Control Board/Main Control Board

The temperature control board directs voltage to the refrigerant systems. If defective, the temperature control board may send continuous voltage to the refrigerant systems. This will make the fridge colder than desired.

The main control board is the brain of the appliance. It regulates the voltage that is supplied to the entire unit. If faulty, the main control board may cause the compressor and evaporator fans to overwork. This will result in the fridge getting too cold and freeze food.

Diagnosing the main control board is difficult. You can however inspect for loose wires and burning.

Since these two are not so easy to diagnose, we recommend you troubleshoot the above-mentioned parts first. And only consider these if the problem remains unsolved.

If replace either of these, we recommend that you get a repair technician.

LG Fridge Freezing Food in Crisper – Solved

The first step is to check if the temperature is too low. If it is below the recommended range, which is between 33 and 40 degrees Fahrenheit, increase it by one or two degrees. Monitor the fridge to see if food continues freezing in the cripser drawer.

If the problem continues, try adding more items to the drawer. It may not have enough content to absorb the amount of cold air in it. Keep it at least half full but never too full or empty. And if the drawer has an adjustable temperature feature, take the setting to a warmer point without adjusting the refrigerator temperature.

Back of LG Refrigerator too Cold and Freezing Food – Qucik Fix

The back of any refrigerator is one of the coldest parts because of the proximity to the vents. If food is freezing at the back of your refrigerator, ensure it is not too close to the vents. Water-rich foods will freeze faster than others, especially if they are too close to the vents.

Also, increase the temperature to a warmer point if the problem persists. Keep it between 33 and 40 degrees Fahrenheit. Then, monitor the refrigerator to see if the food keeps freezing. Excessive condensation can also cause freezing at the back and bottom due to the cold air.
