Good Morning friend, thank you for your inquiry!
I see that you are having trouble with your Frigidaire dehumidifier displaying an error code of "F2". Typically, an "F2" error code stands for a miscommunication error. This could be a possible problem with a sensor or control panel. I would suggest performing a reset and that can be completed by disconnecting the power from your dehumidifier for roughly ten minutes. If you are still under warranty I would recommend contacting your manufacturer to see if any additional assistance can be provided. Hopefully this is helpful. -Matt

Hello - Typically error code F2 indicates a sensor failed has occurred on the dehumidifier. You may want to contact your manufacturer to verify if the part is available and can be replace. Some do, some don't. Also confirm if the unit has a limited warranty on such concern.

To figure out what Code F2 is, I took a look at the Owners Manual for the Model # AD70USS, Strangely, the Owners Manual doesn't list an F2 Code or any codes for that matter. Because that model number humidifier, does not have an LED screen.

Never the less, to reset your unit using an alternate method. Turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet. Wait 12 - 15 minutes before plugging it back in. Then turn the Master ON/OFF Switch to ON and the dehumidifier should have reset itself. If it doesn't check the positioning of the water bucket, to make sure it's contacting the safety switch. Eventhough, you're using a drain home, it's still important.

Hope this helps you solve the problem.

If the display reads "F1" or "F2", a sensor has failed. Contact your Authorized Frigidaire Service Center.

Faulty tube sensor.

When I searched this error code, I found that F-2 means bad sensor. I found no further information as to what sensor it was. You don't give the name of the manufacturer, so I couldn't search from that perspective.

If it is a bad sensor, you may require professional repair.

Before I took it anywhere to be worked on, I would be certain that the catch bucket was setting square (indicating no water in the bucket).

Thanks for your interest in FixYa.com

F1 is room temperarure sensor error. F2 is tube temperature sensor error.

The room sensor usually is located in the front of the condenser. The tube sensor is usually plugged in a tube near the condensor.

The tube temperature sensor (thermistor) should be about 10K ohms.
