Frigidaire H1 Code: What It is and How to Fix It

Mr. Appliance technician using an infrared thermometer to test the internal temperature of a freezer drawer.

The Frigidaire H1 code on a refrigerator means that your appliance’s internal temperature is too warm. To solve this problem, you’ll need to check the temperature settings in your refrigerator and freezer to ensure that they are in the manufacturer-recommended range.

But resetting your appliance’s temperature isn’t always as easy as pressing a button or cranking a dial. Sometimes a part malfunction is at play. Your refrigerator’s H1 code often serves as a clue that you need to have your appliance checked by a professional.

The professionals at Mr. Appliance can determine why your temperature settings are too warm. We will also advise you on how to maintain your refrigerator to prevent this issue from happening in the future.

Causes for the Frigidaire Refrigerator H1 Code

Although there is only one H1 error code for your Frigidaire refrigerator, numerous causes for this code exist. Luckily, there is a solution for each of these causes.

Below are some common reasons why you might be receiving this code, along with potential solutions to make sure that you don’t receive it again.

Dirty Condenser Coils

The condenser coils on your refrigerator keep heat from overriding the cold air in your appliance. When these coils get dirty, they can’t do their job properly. This can cause your compressor to work harder to maintain a colder temperature and, consequently, overheat. In this instance, the H1 message means that your refrigerator is warmer than it should be.

To fix this problem, you’ll need to clean and maintain your condenser coils. If you suspect that your compressor has overheated as a result of dirty condenser coils, call an appliance professional to check the status of your compressor’s motor.

Defective Evaporator Fan Motor

If your freezer’s evaporator fan motor fails to run, frost can build up on your appliance’s evaporator coils. In this case, the H1 error code means that your freezer’s temperature is too warm.

To rectify this, your evaporator fan motor will need to be either repaired or replaced by a qualified appliance professional.

Faulty Door Gasket

Door gaskets help to seal your appliance’s door and keep warmer air out. When they malfunction, it allows warm air to enter through cracks in your refrigerator’s door. The abundance of warm air triggers the H1 error code.

Door gaskets that don’t allow your fridge door to close properly will need to be replaced in order to restore the efficiency and function of your appliance.

Incorrect Temperature Control Settings

If your temperature settings are too high, it can make your appliance rise above the recommended temperature.

You can usually fix this issue by manually adjusting your appliance’s settings. Check your instruction manual for recommended temperatures.

If this still does not work, it’s best to contact your local appliance professional.

Blocked Air Vents

Air vents help to regulate your refrigerator’s temperature. When they are obstructed with ice or food items, your appliance can’t evenly distribute cold air. This causes the temperature in the rest of the refrigerator or freezer to be too warm.

Make sure that your appliance’s air vents are not blocked. If you notice a coating of ice over your vents, try defrosting your refrigerator by removing your items and turning off the appliance. The defrosting process can take up to 12 hours.

Malfunctioning Defrost System

Your appliance’s defrost system helps prevent frost from gathering on the evaporator coils. When the defrost system malfunctions, ice buildup on the evaporator coils prevents proper airflow and doesn’t allow the appliance to cool properly.

If your defrost system is failing, it may require extensive part replacement or repair. Contact your local appliance professional for a careful inspection.

Broken Thermistor or Control Board

Your appliance’s thermistor sends messages to the control board to regulate temperature. If your thermistor is broken, it may be sending incorrect temperature readings to the control board.

When the control board itself is malfunctioning, the thermistor may be fine, but faulty electronic components of the control board may be preventing it from working properly.

To resolve this issue, allow an appliance professional to check the status of your thermistor and control board.
