Understanding a Frigidaire Dehumidifier’s F0 Code [Easy DIY Fixes]

Frigidaire Dehumidifier F0 Code

As Frigidaire dehumidifier owners, seeing the F0 code flash on our appliance’s digital screen is a nightmare. After all, it’s a clear sign that something’s wrong.

But this doesn’t mean that you should replace your dehumidifier right away. Let’s identify the meaning behind the F0 error code first and see how you can fix it yourself. 

What does the Frigidaire dehumidifier F0 code mean?

The Frigidaire dehumidifier’s F0 code signifies a general malfunction in the appliance. It means that something’s wrong with it and must be inspected.

While the code doesn’t specify the exact issue, it could be a problem with the power source, temperature, humidistat, or other broken components.

The best course of action is to go through all these possible issues to find the main cause. This article will help you identify and easily fix the problem on your own. 

Breaking Down a Frigidaire Dehumidifier’s F0 Error: Causes and DIY Solutions

Our dehumidifier comprises several fundamental parts, and when one of them malfunctions, it could trigger the F0 error code. Check out this list of its possible causes and solutions. 

Power supply issue• Turn your dehumidifier off and see where it is plugged in.
• The appliance must be connected directly to an outlet and not an extension cord.
• If the dehumidifier is plugged into an extension cord or wireless power bank, remove it.
• Find an outlet that’s directly connected to your home or establishment’s power supply.
• Transfer your dehumidifier and plug it directly into that outlet. 
• Turn your dehumidifier on again. 
Incorrect room temperature• Use a thermometer to measure the room’s temperature.
• If you’re in an airconditioned space, check the control panel or the remote’s screen to see how cold it is. 
• See if the room’s temperature is between 41° – 90°F. If not, adjust it accordingly.
• Restart your dehumidifier. 
Broken humidistat• Unplug your dehumidifier from the power source. 
• Using a screwdriver, unscrew and remove the dehumidifier’s cover.
Search for the humidistat. It is a small digital device near the dehumidifier’s control panel.
See if there are any cracks, dents, and other signs of damage on the humidistat. 
• Next, remove the wires connected to the humidistat. Remember their placements for reassembly later.
• Detach the humidistat from where it’s mounted using a screwdriver.
• Get a multimeter to test if the humidistat is working. 
• You can get a multimeter in your nearest hardware store or appliance center.
• Connect the ends of the multimeter’s probes to the humidistat. 
• The humidistat’s resistance should at least be 1000 ohms.
• If the multimeter’s reading is any lower, you’ll need to purchase a new humidistat.
• You can order a new one from Frigidaire or other appliance stores selling its parts.
• Once you have a new humidistat, reattach the wires and screw it securely on the mount.  
• Next, put the dehumidifier’s cover back. Secure it with screws. 
• Plug the appliance directly into a power source and turn it on.
Frozen coils • Turn off and unplug your Frigidaire dehumidifier. 
• Unscrew and remove its cover. 
• Look for the evaporator coils, which are thick metallic tubes arranged in a grid.
• Using a screwdriver, remove the other parts of your dehumidifier to access them.
• Set the removed parts aside and wait 4 to 12 hours for the ice on your evaporator coils to melt. 
• When the ice is gone, reassemble your dehumidifier.
• Put the dehumidifier’s cover back. Plug it in and turn it on again. 

The causes of the F0 error code come with easy solutions that you can do by yourself. Just go through these instructions one by one and you’re all set. 

Power Supply

Dehumidifiers need a voltage of 115V-10% to function without any problem. Extension cords and power banks unfortunately can’t supply this power consistently. 

These extension cords and batteries also have high risks of short-circuiting, which can harm your appliance. Insufficient power will also cause an F0 error.

Solution: Turn your dehumidifier off and follow its cord to see where its power source is.

If the dehumidifier is using an extension cord or power bank to power up, remove it. Find an outlet that’s connected to the house or building’s main power supply.

Relocate your dehumidifier and plug it directly into that outlet. Turn your dehumidifier on again.

Incorrect Room Temperature

Your dehumidifier won’t operate properly if the room is too cold. The lack or absence of moisture will be detected as an error by your Frigidaire dehumidifier. 

Solution: Check the room’s temperature first using a thermometer. If the area has air conditioning, the unit’s remote control or control panel displays how cold it is.

The room’s temperature must be between 41° – 90°F. If it’s too cold, adjust it accordingly. 

Restart your dehumidifier by pressing the on/off button twice. 

Broken Humidistat

The humidistat is in charge of regulating the moisture levels in the room, making sure that it is just the right amount.

It stops the appliance from absorbing water once it detects that the humidity is just right or according to how you set it. If the humidistat breaks, the dehumidifier won’t function properly. 

Solution: Turn off and disconnect your dehumidifier from the power source. 

Remove the dehumidifier’s cover and search for the humidistat underneath it. It is a small dial or digital device near the controls or knobs of the appliance.

Look for any signs of damage such as cracks and dents. Next, detach the wires connected to the humidistat. 

While removing the wires, remember their placements for when you put them back later.

Remove the screws that are keeping the humidistat mounted. After detaching it, fetch a multimeter for testing.

If you don’t have a multimeter, you can buy one at an appliance store. 

Connect your multimeter’s probes to the humidistat to get a reading. The resistance should be at least 1000 ohms.

If you get a lower number, your humidistat is broken and needs to be replaced. Get a brand new one from Frigidaire or other appliance stores.

Reattach the wires on your new humidistat and screw it on its mount. Next, put the dehumidifier’s cover back securely.

Plug the appliance in and turn it on to see if it’s working. If the problem persists, contact a technician to help you with troubleshooting. 

Frozen Coils

The inside of the dehumidifier can get really cold, causing ice can build up on its evaporation coils. 

When the coils get frozen, they hinder the airflow and moisture collection. This leads to an error. 

Solution: Remove your Frigidaire dehumidifier from its power source. Next, remove its cover so you can check if the coils have been frozen. 

The evaporator coils are the big metallic tubes taking up the center of the dehumidifier. You’ll notice other parts obstructing your access to it.

Remove the other components using a screwdriver but remember their positioning. After disassembling them, wait for the ice on the coils to melt. 

The accumulated ice will go away within 4 to 12 hours, depending on how thick it is and the room’s temperature. You can reassemble your dehumidifier when all the ice has thawed.

Place the cover back securely. 

The number one key to fixing your Frigidaire dehumidifier’s F0 error code is patience. Combine it with these easy DIY steps, you can fix your appliance without breaking a sweat. 

Getting an expert’s opinion is also important. Asking for assistance or advice from a technician on how to better take care of your dehumidifier will help prolong its lifespan.
