It may seem like a weird problem to have, but you’re not alone if your LG refrigerator freezer is cold but refrigerator is warm. Before assuming something is broken, you can troubleshoot and possibly fix some of the causes yourself.

Troubleshooting Guide: LG Refrigerator Freezer Is Cold but Refrigerator Is Warm

While the problem may seem complicated, the solution may be fairly simple. Use this guide to find out whether or not professional service is necessary to fix your refrigerator:

Overstuffing

Believe it or not, but there is such this as having too much food! A freezer that has a lot of food is a common cause for a refrigerator won’t get cold but freezer will issue.

What causes it: When the freezer is overstuffed, it can block the airflow between compartments. In other words, not enough cold air will make its way to the refrigerator compartment.

How to fix it:  Free up some space in the freezer. First, throw out any old food. Then, rearrange the shelving or look into getting some refrigerator organization storage containers.

Condenser Coils Need Cleaning

One of the most common reasons why your LG refrigerator freezer is cold but refrigerator is warm is due to dirty condenser coils. Dust, hair, and lint collect on these coils over time.

What causes it: The coils help maintain cold temperatures by releasing heat. When they get dirty, the dust and debris can block heat from leaving the coils.

How to fix it: Refrigerator coil cleaning is simple and should be done every six months (more if you have pets). Just follow these steps:

  1. Pull the refrigerator from the wall and locate the coils.
  2. Unplug the refrigerator.
  3. Vacuum any dust and lint from the coils.
  4. Use a brush to remove any remaining debris.
  5. Vacuum the refrigerator coils one more time.

Faulty Evaporator Fan Motor

If your LG refrigerator freezer is cold but refrigerator is warm AND your refrigerator runs loud, there’s probably an issue with the evaporator fan motor.

What causes it: The evaporator fan circulates cold air from the freezer to the refrigerator. When the motor fails, the fan can’t move cold air, and you’ll find your LG refrigerator not cooling but freezer works.

How to fix it: Locate the evaporator fan behind the freezer’s back panel. If you try to move the fan blades by hand and they won’t move easily, then the fan motor must be replaced.

Defective Thermistor

The thermistor plays an important part in regulating refrigerator temperatures. It monitors the temperature and tells the compressor and evaporator fan to turn on or off when needed.

What causes it: When the thermistor fails, the compressor and evaporator fan will not run at the appropriate times, causing irregular temperatures.

How to fix it: Locate the thermistor and test it with a multimeter. If there is a continuity issue with the part, then it needs replacement.

Defrost System Failure

If you’ve followed all the instructions above and are still wondering, “why is my fridge isn’t cold but the freezer is,” it’s probably an issue with the defrost system. The defrost system consists of many parts working in conjunction with each other to keep it going. If something goes wrong and your refrigerator can’t defrost properly, ice will buildup and block proper airflow.

What causes it: It’s unlikely that the entire system is defective. Rather, one of the many components that keep it going has probably failed. A broken defrost thermostat, timer, or control board may be the culprit.

How to fix: Since it’s a difficult problem to diagnose, it’s best to call in the experts to repair the defrost system.
