Frigidaire Refrigerator "Hi" Error Code

Frigidaire side-by-side refrigerators are known for their innovative design and reliable performance. However, like any other appliance, they may encounter occasional issues. One common problem that some users may encounter is the "HI" error code in a Frigidaire Refrigerator. If you're facing this issue, don't worry! In this blog, we'll explore the possible causes of the "HI" error message on your Frigidaire fridge and guide you through the troubleshooting steps to resolve it.

Side by Side Frigidaire Refrigerator with HI Error Message

What Does the "HI" Error Message Mean?

When your Frigidaire side-by-side refrigerator displays the "HI" error message, it usually indicates a problem related to the freezer sensor. This sensor is responsible for monitoring the temperature in the freezer compartment. When it malfunctions or detects an anomaly, the error code "HI" is triggered to alert you to the potential issue.

Troubleshooting Steps:

  1. Check for Frost Buildup: The first step is to inspect the freezer compartment for any signs of frost or ice buildup. If frost accumulates around the sensor, it can affect its accuracy and trigger the error message. Defrost the freezer and clean up any frost or ice that may be obstructing the sensor.

  2. Inspect the Freezer Temperature Setting: Ensure that the freezer temperature setting is appropriate. The recommended temperature is usually around 0°F (-18°C). If the temperature is set too low or too high, it might lead to irregular sensor readings.

  3. Reset the Fridge: Sometimes, electronic glitches can cause the "HI" error message to appear. To rule out this possibility, try resetting the refrigerator by unplugging it from the power source for a few minutes, and then plug it back in. This action may clear the error code and restore normal operation.

  4. Check the Freezer Sensor Connection: The "HI" error message could be triggered by a loose or faulty connection between the sensor and the control board. Carefully inspect the wiring harness and ensure that it is securely connected. If you find any damaged wires, they will need to be replaced.

  5. Test the Freezer Sensor: If the above steps don't resolve the issue, it's possible that the freezer sensor itself is defective. You can perform a resistance test on the sensor using a multimeter to check if it's within the specified range. If the sensor fails the test, it will need to be replaced with a genuine Frigidaire part.

  6. Seek Professional Help: If you're uncertain about performing the troubleshooting steps yourself, or if the "HI" error message persists despite your efforts, it's best to contact a certified Frigidaire technician. They have the expertise and specialized tools to diagnose and resolve complex issues effectively.


Experiencing the "HI" error message on your Frigidaire side-by-side refrigerator can be concerning, but it's essential to approach the situation calmly and methodically. By following the troubleshooting steps outlined in this blog, you can often identify the cause of the error and potentially resolve it on your own. Remember that safety comes first, and if you're unsure or uncomfortable with DIY repairs, it's always wise to consult a professional technician to ensure the optimal performance and longevity of your Frigidaire fridge.
