Common Refrigerator Fault Codes

While it can be a shock to see a refrigerator fault code on its display panel, it’s not always bad news. In fact, it can be a blessing in disguise. The fault code will tell you which part of the fridge is faulty and consequently, what needs to be repaired or replaced.

In many cases, faults only require a simple fix you can manage by yourself but in some instances, you may need to call for professional help. If you do, the fault code will make diagnosing and repairing your refrigerator a faster and more efficient process, which will help to reduce your costs.

In this article, we explain the most common refrigerator fault codes for leading brands including Whirlpool, Samsung and GE, so you can identify exactly what’s wrong with your fridge.

The Fault

The Likely Fix


The temperature is rising excessively

Make sure the refrigerator and freezer doors have been closed properly and replace the door seals (or gaskets) if necessary. Then press the system check button to clear the error code. If the PF code appears, the error was caused by a power failure. Keep the doors closed and the temperature should return to its normal level.


The power has been interrupted

Make sure the fridge is securely plugged in. If the power cord is damaged, get it replaced. Press the System Check button to clear the error code and check for any other failures.


The ice maker is not working properly

Check for jammed ice cubes in the ice mold and remove them. After which, ensure that there is water in the ice maker. Press the System Check button to clear the error message. If the CI code reappears, the ice maker assembly will need to be replaced.


Defrost system error

If you see this error code, it means that the defrost cycle has not been operating properly for at least 48 hours. Check if there are loose wires in the defrost system and get a new wire harness if it is damaged. Similarly, replace the defrost heater if it has been damaged, resetting the system by pressing the System Check switch. If there’s an ambient temperature of lower than 55 degrees F, it may be understandable that the fridge has not defrosted itself for 48 hours or more.
