What are refrigerator error codes & how many are there?

Refrigerator error codes appear as alphanumeric characters on the control panel or digital display to indicate specific issues or malfunctions within the machine. These codes are generated by the refrigerator’s internal diagnostic system and are designed to assist users and technicians in identifying and resolving problems.

Since each refrigerator brand and model can have its own unique set of error codes, the meaning of the error codes can vary. They generally provide information about issues such as temperature irregularities, faulty sensors, fan failures, defrost problems and more.

Always check the refrigerator’s technical sheet to find a detailed explanation of the error codes specific to your fridge model.

Do all refrigerators display error codes?

No. The presence of error code displays depends on the design and features of the specific refrigerator. More advanced and sophisticated refrigerators are more likely to incorporate error code systems for troubleshooting.

More basic refrigerators, especially older models from before the 1990s, may not have error code displays. In these cases, troubleshooting is often limited to basic visual inspection, temperature checks, listening for unusual sounds and general testing with a multimeter.

What are the most common types of refrigerator error codes?

Some of the most common types of error codes that appear across many refrigerator models and brands include:

Temperature-related errors

These codes indicate temperature irregularities, such as high or low temperatures beyond the set range. They may be attributed to issues with the thermostat, control board, temperature sensors or cooling system.

Defrost system errors

These codes typically signify problems with the defrosting system, which could include a malfunctioning defrost heater, defrost timer, thermistor, thermostat, or control board.

Door-related errors

Door-related codes could mean there are issues with the refrigerator doors not closing properly, a faulty door switch or a door that’s staying open for an extended period. A faulty gasket (also called a door seal) can also prevent the doors from staying closed properly.

Power or communication errors

Issues with the power supply, electrical connections, or communication between parts in the refrigerator can cause these kinds of codes. Your refrigerator may experience a power or communication erorr after a power outage. To prevent many of these errors, it’s recommended to invest in a good quality surge protector for your machine.

Common refrigerator error codes by brand

Error codes on a refrigerator are displayed on the digital display panel, which is typically located on the front of the appliance, often on the door or above the water and ice dispenser. These error codes may be letters, numbers or a combination of both. Each error code corresponds to a specific problem, such as issues with temperature regulation, fan function or the defrost system. Most manufacturers provide a guide (often in the user manual or on their website) explaining what each code means and the suggested steps to resolve the issue.

Here are some common error codes that may show up on popular refrigerator brands:

Bosch refrigerator errors

E1/E2 – Refrigerator or freezer temperature sensor failure. 

E3 – Ice maker temperature sensor failure. 

Frigidaire refrigerator errors

Er CE – Indicates a temporary communications interruption.

SY EF – Evaporator fan motor fault code. 

GE refrigerator errors

dE – Usually indicates a defrost fault, no defrost cycle in over 3 days or no current detected. 

CI – Ice maker current isn’t being detected. Check the ice maker.

LG refrigerator errors

dH – Usually means there’s a problem with the defrost system.

IF – An ice maker fan fault.  

FF – A freezer fan motor fault. 

ER FS – Typically points to a problem with the freezer sensor.

Samsung refrigerator errors

39e – Ice maker function error. 

5E – Indicates a problem with the refrigerator defrost system. 

88 88 with one of the lines flashing – Typically means there’s an interruption in electronic communication. The specific line that’s flashing will identify the failure.

22E, 22C – Evaporator fan motor faults.

1E/SE – Freezer temperature sensor failure.

Whirlpool refrigerator errors

PO – Usually indicates a power or electrical problem. 

C – Typically means a refrigerator or freezer compartment thermistor has failed. 

d – The air door motor is stuck open. 

How can I troubleshoot refrigerator error codes?

Here are some general steps to troubleshoot and fix refrigerator error codes:

Check the technical sheet & user manual

Some error codes may be directly related to specific parts that need to be reset or replaced, such as defrost sensors or control boards. Follow the instructions provided in the technical sheet or service manual to determine if this is the case.

The technical sheet may also include basic information about common error code meanings and solutions. If there are any diagnostic tests listed in the technical sheet, try running those on your machine by following the instructions.

Perform a power reset

This is also known as power cycling, which simply means to turn an appliance off and back on. Unplug your refrigerator from the power source, wait for a few minutes, and then plug it back in. Unplugging the refrigerator and plugging it back in can sometimes clear temporary glitches or errors.

Look over the refrigerator for any visible problems

• Make sure the refrigerator is leveled
• Check for loose connections
• Verify that the doors are closing tightly. Inspect the door seals for any signs of damage or wear. If necessary, replace the seals.

Check the temperature

Incorrect temperature settings can trigger error codes. A refrigerator should be set to around 40°F. Adjust it as needed.

You can also use an independent thermometer to check the temperature. If the fridge is warmer than usual, then you’ll need to investigate to find out if a part has failed.

Clean the condenser coils

Over time, dust and debris can accumulate on the condenser coils, which reduces their efficiency and can potentially cause error codes. You should clean the coils with a vacuum or a brush at least once every 6 months to remove any buildup.

How can I prevent error codes on my refrigerator?

While it’s not always possible to completely prevent error codes from occurring, you can take certain preventive measures to reduce the likelihood of encountering them:

• Keep the refrigerator clean and free from dust, debris, and food spills. Regularly clean the condenser coils, vents, and door seals according to the manufacturer’s instructions.
• Avoid overcrowding the refrigerator since this can reduce airflow and lead to temperature imbalances. Allow space between food items for adequate cooling and ventilation.
• Regularly check and monitor the refrigerator’s temperature to make sure it stays within the recommended range.
• Gently open and close the refrigerator doors to prevent damage to the door seals or misalignment. Never slam the doors shut.
• Protect the fridge’s power supply. Use surge protectors or voltage stabilizers if necessary to protect it from power fluctuations and outages.
• Periodically inspect the refrigerator for any signs of wear, loose connections, or unusual noises. Addressing small issues sooner rather than later can often prevent them from becoming larger and more expensive problems.
