How to Fix Frigidaire Dehumidifier FO Code Error? Troubleshooting Guide

Share your love

A dehumidifier is a device that regulates the humidity in the air. The manufacturer Frigidaire is well-known for producing refrigeration equipment. However, an F0 error can occur even in products from a well-known brand. The code indicates many types of errors.

In general, it indicates a problem with the operation of the equipment but does not specify the source of the problem. It can also be a violation of the temperature regime or power spikes. F0 also indicates a hygrostat or sensor malfunction and a lack of refrigerant. Only by understanding the dehumidifier’s features will you be able to solve the problem.

In this article, we’ll explain what the F0 code means and provide some suggestions for resolving it. To understand what the F0 code indicates, we must first understand how a dehumidifier works.

How Does a Dehumidifier Work?

A dehumidifier works by sucking warm air currents into its coils via a fan. Warm air contracts as it travels through the refrigerated coils of the machine, leaving condensation inside the dehumidifier.

Condensation falls into a storage tank linked to the dehumidifier one droplet at a time as it forms. Cooler, drier air is discharged into your home through the machine’s other side.

Your dehumidifier must be capable of reducing the moisture in the air to a relative humidity of 30 to 50% in a 68-degree environment. Many dehumidifiers include a meter that measures the relative humidity in your home, and you can change the humidity to any percentage you like.

How Does a Dehumidifier Work

The Parts Of a Dehumidifier

The majority of dehumidifiers are made up of five parts:

  • Fan Compressor — This compresses and expands a refrigerant gas, such as freon, to cool the dehumidifier’s coils. (For a more thorough description of this cycle, see How Air Conditioners Work.)
  • Reheater — This catches and collects heat generated by the cooling operation.
  • Compressor cooling coils
  • Reservoir

How do all these components work together to extract moisture from the air? It’s straightforward but effective:

  • A fan draws air from the surrounding environment into the dehumidifier. As the air goes through, it comes into touch with the cooling coils of the dehumidifier. These coils use condensation to draw moisture from the air. The moisture accumulated on the coils drips into the dehumidifier’s reservoir.
  • The dehumidifier reheats the air before returning it to the room.

Other components, such as a thermistor, a humidistat, and a control board, help message when to operate, how to operate, and how to function. If any of these components fail, you may receive this error code.

3 Easy Steps To Solve Frigidaire Dehumidifier FO Code

The Code F0 error indicates that your dehumidifier is low on refrigerant, which is frequently the result of a leak in the enclosed refrigerant system.

When the copper cooling coils are devoid of refrigerant, they do not cool, and no condensation forms and falls into the drain bucket when wet air flows over them. This suggests that your dehumidifier is just a glorified box fan.

Here are a few ways to fix this issue:

1. Assessing the Power Supply

Given that a dehumidifier has only a few vital pieces, the problem can only be one of two things. The voltage is the first possible cause of the f0 problem.

Dehumidifiers require a certain amount of power to perform correctly. The 115V-10% outlet should be utilized where the machine is used. Inspecting your outlet to ensure it receives adequate power would be best.

One of the significant concerns with humidifiers is that they are not usually plugged directly into an outlet. They try to modify them for someone with health issues, such as a child or spouse; as a result, extension cords or power bars are commonly used to transmit electricity to the dehumidifier.

This could be the source of your issue. The issue could not be with the outlet at all. It could be the way you’re attempting to power the machine.

2. Temperature Testing

Dehumidifiers work only under specific parameters, one of which is temperature. The room temperature should be between 41 and 90 degrees Fahrenheit. When the refrigeration in a room is impaired, a dehumidifier will not function properly.

It also does not function in temperatures above 90 degrees. A dehumidifier will keep the area slightly cooler, but it is not an air conditioner and will struggle to cool down air to collect moisture if the room is too hot.

3. Humidifier Resetting

Unfortunately, you can’t do much about this error code since parts like the humidistat, compressor, or thermistor require the services of a certified service specialist. You might try resetting the unit to see if the code has been cleared.

Resetting your Frigidaire is straightforward. Unplug it from the outlet, wait five minutes, and then plug it back in. This should reset the components and clear the error code. To see if the problem has been fixed, reset the controls and restart the dehumidifier.

What Should You Do If the Error Persists?

You can examine specific items, such as the sensor, to do your diagnostics. If the problem appears again on display, call a Frigidaire Authorized Service Center. You can begin by dialing the support center number indicated in your owner’s manual.

You should also obtain your warranty details if the repair is covered under a guarantee. If your dehumidifier is new enough, the repair may be covered.

Can You Recharge A Dehumidifier?

Both yes and no. It depends on the sort of dehumidifier you have. Yes, if the device uses a coolant, also known as a refrigerant, it can be recharged. Those dehumidifiers with that ingredient keep the air in your home cool.

If it loses power, you must replace it with no coolant for your dehumidifier to function correctly. Other types of dehumidifiers cannot be recharged.

Because not every portable dehumidifier is made the same, you should research the charging method for your specific machine. These distinctions may include specialized safety features, the absence of which may result in less desirable outcomes.

Is my F0 Error related to my Unit Freezing Up?

This could be one of the problems impacting your machine and resulting in the f0 error. It may freeze if you continually run it hard or have it in a place cooler than 41 degrees.

When you overwork a dehumidifier or air conditioner, moisture can form on the coils.

You can solve this problem on your own. Switch off and unplug the system for a few hours before attempting to reactivate it. Once the coils have thawed, they may begin to work again.


So there you have it, a comprehensive tutorial on how your dehumidifier works, what the F0 code indicates, and how to fix the problem.

Frequently Asked Questions (FSK)

Why is my Frigidaire dehumidifier always shutting off?

If your dehumidifier continues shutting off, the sensor may not correctly measure the humidity level, causing the device to shut down before reaching the target level. Some dehumidifiers include a thermistor that operates in conjunction with the sensor, which can also fail.

How can I determine if my dehumidifier compressor is working?

If the dehumidifier’s blower is running, it is possible that the compressor is not working. Check if the dehumidifier’s indicator light confirms that the compressor is working.

What happens if the compressor breaks?

Your air conditioner cannot function without the compressor, so AC compressor failure is a big deal. When your ac compressor fails, less air comes out of the vents, the air that does come out may be warm, and the system may run continuously without cooling your home.

How much are dehumidifier repairs?

Dehumidifier repairs often cost between $50 and $200. Homeowners can resolve many difficulties independently, but an HVAC specialist should address more complex concerns. Freeze-up clogs in drain lines, filthy coils, and component failure are all common concerns with dehumidifiers.

What are some common dehumidifier issues?

Excessive noise, leaking water, and a broken fan are all frequent dehumidifier issues. Most of these fixes do not require a high mechanical competence, but you must still follow the correct procedures.

What is the lifespan of a dehumidifier?

Dehumidifiers typically have a lifespan of five to ten years. It is critical to maintaining your dehumidifier to extend its lifespan. Change the air filters regularly, clean the condensing coils and exhaust grilles, and empty and clean the water bucket.
