Frigidaire Refrigerator H1 Code: Causes & 8 Ways To Fix It

Errors are one of the ways that your Refrigerator tells you if it has an error or any malfunction. However, it can be frustrating if your Refrigerator starts blinking an error code and you don’t understand what it means.

If your Frigidaire refrigerator is blinking the H1 code, you don’t have to worry because, in this article, I will tell you why your Frigidaire refrigerator is blinking the H1 code. Moreover, I will explain how to solve each cause of this error in detail.

Frigidaire Refrigerator H1 Code
The Frigidaire refrigerator H1 code indicates an issue with the temperature of the fridge or freezer compartment, which might result from a faulty control board, Thermistor, or door seal. It could also be the result of an open door or poor ventilation.

Causes of Frigidaire Refrigerator H1 Code

The H1 error code is related to the appliance’s temperature, either the freezer or the refrigerator compartment. So, the H1 appears when the temperature exceeds a certain point.

The H1 code also can be displayed when the freezer temperature reaches or exceeds 26 degrees Fahrenheit. If the freezer door is left open for more than five, this affects its temperature and activates the H1 code.

Another reason why your Frigidaire refrigerator might be showing the H1 code is if the Thermistor is defective or the control board is broken.

There are many reasons behind the H1 code, but you don’t have to worry; I will discuss each reason in detail to make it more transparent.

1- Overloaded Freezer

Overloading your freezer compartment can cause it not to close completely; as a result, the warm air will leak into your freezer, which affects its temperature.

When the temperature of your freezer is affected so it reaches or exceeds 26 degrees Fahrenheit, the Frigidaire refrigerator starts showing the H1 code to alert you.

2- Faulty Door Seal

The door seal is essential to keep your fridge temperature constant, so if the door seal is faulty, the door will not close properly, which leaks the refrigerant increasing your refrigerator temperature.

As I have mentioned, the H1 code error is related to your fridge temperature, so whenever your freezer or refrigerator compartment is not closed completely, it’s displayed on the fridge.

Most modern refrigerators have an alarm triggered when your door is open for more than five minutes. If the door alarm is faulty, the H1 error will be displayed continuously to alert you.

3- Unleveled Refrigerator

If your Frigidaire refrigerator is not level or leaning, it can cause the H1 error code to appear. The Refrigerator has to be on a level surface. If the Refrigerator is leaning to one side, you should try to level it using a flat lever.

4- Insufficient Exterior Ventilation

Ventilation is essential to your refrigerator cooling process, so the exterior ventilation must be sufficient to ensure no errors.

If your fridge is too close to the walls, it can block air circulation and decrease ventilation. The room must also be suitable for the fridge and have enough ventilation.

5- Defective Circuit Board

The H1 error code might result from a defective circuit board; the electronic board fault is one of the common reasons for the H1 error code.

Unfortunately, if the circuit board is defective, you must replace the whole control unit to solve the issue.

6- Defective Thermistor

The Thermistor is responsible for the temperature of the fridge; if the Thermistor is faulty, it can lead to the H1 error code. The Thermistor sends signals to the control board to operate the fan and compressor.

You will need to check the Thermistor to know if it’s defective, you can do so using a multimeter. Set the multimeter to continuity and test the Thermistor; it’s defective if it shows no electrical continuity signals.

If the Thermistor is defective, the control board will have no signals to operate the evaporator fan and the compressor, increasing¬†the fridge’s temperature. As a result, the H1 will start blinking on your fridge.

7- Ice Accumulation

Most modern refrigerators have an auto-defrost feature, which prevents any ice accumulation. If your Refrigerator lacks this feature, the ice accumulation will affect the compressor’s functionality.

At ice accumulation, the compressor generates a high amount of heat which increases the Refrigerator’s temperature, resulting in the H1 error code.

8- Power Outage

When your Frigidaire refrigerator goes through a power outage, it will probably display two errors after the power is back. The H1 and PF error codes, the PF code stands for power failure. The H1 appears because the temperature increases when the power is cut off.

How to Fix Frigidaire Refrigerator H1 Code

After discussing the reasons behind the H1 error code displayed on your Refrigerator, now, I will discuss the solutions. I will explain how to solve each cause to get your Refrigerator back working correctly.

1- How to Fix an Overloaded Freezer?

If your freezer is overloaded, it can get in the way of the freezer door and block it from closing. If the door is open for five minutes or more, the temperature will increase; therefore, you must organize your freezer so it closes properly.

It’s recommended that you don’t overload your freezer to give it a chance to cool efficiently and avoid the H1 error code flashing on your fridge’s display.

2- How to Fix a Faulty Door Seal?

If your door seal is faulty, it will make your door not close properly; therefore, you will need to either clean the seal or replace it if it’s defective. You can clean the door seal using a piece of cloth and warm water, add some soap to the water and dampen the cloth in it.

Start cleaning the seal using the cloth to remove any debris or dirt blocking the seal from closing. If the problem continues after cleaning the seal, you will need to replace the seal with a new one. Kindly follow the following steps to replace the faulty door seal:

  1. Place the new seal into a bucket of warm water to make it easier to install.
