When your refrigerator is malfunctioning, it can cause significant problems for your family. Fortunately, many newer brands are equipped with error codes that are helpful when it comes to troubleshooting and ultimately fixing the appliance. Depending on the brand and model you own, error codes may vary, however.
LG Refrigerators
If you have an LG refrigerator, you should keep an eye out for a four-letter code displayed on the LCD screen near the ice dispenser. Errors may display slightly differently depending on the model. Most error codes begin with "ER," "E" or "r." From there, additional letters will be added.

Code "OF F" means that the refrigerators demo mode is selected. To change this, press and hold the "refrigerator" and "ice" buttons at the same time.
Code "IS" or "15" indicates a problem with the ice maker or the sensor overseeing the production of ice. For this error, you will need to get help from a repair technician.
If your error code reads "67," there is an object or another problem preventing the door from closing properly. If moving items in the refrigerator does not resolve the issue, you will need to seek professional repair assistance.
If your error code reads "gF," it means that there is an issue with the water pressure or flow sensor. You may try to increase the water pressure slightly to see if the problem persists. If this doesn't result in the error code going away, you should seek a repair for your appliance.
Error codes like "rF" indicate a problem with the fan motor of the refrigerator, and "r5" means an issue with the refrigerator sensor. In both cases, repairs will be needed.
An error containing "dH" means there is an issue with the appliance's defrost cycle, and that the unit spent more than one hour attempting to defrost. To troubleshoot this problem, you may unplug the refrigerator for two minutes to reset the system. When you plug it back in, the unit may resume normal operations and attempt to defrost again. If the error persists, you may need to call for service.
Kenmore Refrigerators
If you have a Kenmore refrigerator, you will have different error codes than if you own an LG model. A code that reads "Er FS" indicates a problem with the freezer sensor. You can check the relevant wiring for connectivity. If the issue persists, you may wish to call for service.
Codes like "F dS" or "r dS" mean that there is a freezer or refrigerator defrost sensor. This could be due to a short or disconnected wiring. You may need to replace the unit's controller assembly, which contains the temperature sensor and the fuse for the defrost system.
A code like "Er IF" means that the fan for the ice compartment has failed. This could be for a number of reasons, including a blocked fan, a defective motor, defective wiring in the circuit or a failed control board. After troubleshooting these parts, you may wish to call for service.
Samsung Refrigerators
If you have a Samsung refrigerator, the error codes you see will be displayed on the door's digital display. They are often numbered, but occasionally they include letters, as well. Common error codes include "OF OF," which often occurs when the door to the unit has been left open and the temperature has risen to a dangerous level. Another common error code is "PC ER," which means that the connection between the door and the refrigerator has been disconnected. Checking the connection is a good first step in troubleshooting the problem. If there seems to be nothing prohibiting proper connectivity, you may wish to call for service.
Samsung codes "4E" and "5E" represent a freezer defrost sensor error and a refrigerator defrost sensor error, respectively. "26E" indicates a problem with the functioning of the ice maker, and "39E" means there is an issue with its sensor.
