Causes of a Frigidaire Dehumidifier F0 error Code

Let’s talk about the major 10 issues of causing F0 Code error.

Dirty Air Filter

If you are not changing your air filter on time and using dirty airs filter; it can be the first cause of F0 error code on Frigidaire dehumidifiers. With the use of appliances; it is normal the dirt clogging and debris on air filter. Whatever the appliances you are using, such as air conditioner, Frigidaire dehumidifier etc. The dirty air filter will block the airflow and it can be a cause of overheating the sensors. In result, you may face the F0 Code error.

Low Refrigerant Charge

The second major reason is; if you have low refrigerant charge in the dehumidifier, it means you are forcing your appliance to work at incorrect temperature. In this case, you will definitely face the F0 error code. There may be the several reasons of low refrigerant charge such as unprofessionally installation is a main issue, during the installation you hit the compressor mistakenly, and if you are using any cutter for some purpose and your cutter slipped to refrigerant lines; it can be a cause of leaks.

So, make sure that you have properly installed your Frigidaire Dehumidifier and have a recommended refrigerant charge in the dehumidifier. The low refrigerant charge may damage your dehumidifier components and can also reduce the lifespan of your appliances. However, if you face this type of error; we recommend you to hire the professional repair services for Frigidaire Dehumidifier F0 Code error.

Temperature Sensor

You are using your appliances from couple of months. With the time period of use; the temperature sensor may reduce its performance and can be faulty or damage. In result, you may face the F0 error code in your dehumidifier.

Humidity Sensor

Another problem about the sensor; Frigidaire dehumidifiers also use the humidity sensor to control the humidity level and measure the moisture level in the air. If your humidity sensor got faulty then in this case you may also face the F0 error code on your dehumidifier. Moreover, your dehumidifier will not control the humidity level accurately.

Electrical Issues

At the time of installation if you have not properly tie the electrical wiring; it can be a major issue in main power supply. Additionally, if you are using the circuit board that are faulty and you don’t know about it. In this case, your Frigidaire dehumidifier may trigger the F0 error code.


The wrong placement of dehumidifier can also affect its performance. For instance, if you have placed your humidifier at the place that is not balances. Moreover, placing the dehumidifier near a heat can also effect on the performance and dehumidifier will be unable to measure the temperature and humidity level in the house or room.

Clogged Drain Line

The F0 error code may also appear on the dehumidifier’s screen due to clogged drain line. Keep checking the drain line and clean it when you see it is necessary to clean. When the drain line get blocked; the dehumidifier will not work properly and it will not decrease the excess moisture from the air. In result, your dehumidifier will show the F0 Error code on screen.


Any earthing in electrical wires or loose grips of electrical wires can be a cause of low power supply to Frigidaire dehumidifier. On the other hand, the parts of dehumidifier (such as compressor, motor and condenser) may be overheating due to un-constant power supply. In result, dehumidifier can show the F0 error code.

Sensor Calibration

Sensor calibration is very important part at the time of installation of dehumidifier. If you have not calibrate them properly, they may not be able to measure the in-house or room temperature. Because every module of dehumidifier is computerized and it is based on artificial intelligence. The incomplete calibration of sensors can be a cause of F0 error code.

Control Board Failure

The last problem that we commonly see at many customers’ end; the failure of control board is also a reason of F0 error code in Frigidaire Dehumidifier. Because the control board is act like a processor and give commands to fan speed, compressor and sensors. Only the wrong power supply can be a cause of control board failure or any short circuit in your electrical wiring.
