Frigidaire 50 pt dehumidifier model FDB50R1has an error code of F2. Means?

SOURCE: Kenmore model # 25800-25801 Error code E3 ?

You can try cleaning the humidity sensor, which is on a circuit board
housed in a nylon clip attached to the cooling coils.
The sensor is in a plastic clip, which can be opened up and cleaned.
Some report success. Didn't work for me.

I ended up rewiring the unit so that a 5v control
line from the lower relay board goes through the SPDT bucket full switch,
turning on the control board when full (so it beeps), but otherwise
enabling the compressor and fan. The fan and compressor
are controlled by relays, which are driven by a ULN2003AN
relay driver. I fed the empty side of the full bucket switch back into
the relay driver to turn on the compress and the fan on high.
I plan to put a dehumidistat in series with this control line;
now it just runs till the bucket is full. A Broan DH100W dehumidistat
is 20 bucks. Could also put in a rotary switch to control the fan speed,
but for me high is enough.

I think this machine is made by Goldstar for Kenmore and Delonghi.
Stuff is just made to break and through away these days, which is a shame.

SOURCE: F2 ON THE DISPLAY / WILL NOT RUN / MODEL FDB30R1

hello sir/mam
this is because of the error in the programme so please switch OFF for 1 mint and switch ON then see the display.

SOURCE: My dehumidifier is giving me a F2 error message and isn't running

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

There may be a clog in the hose, which should be no longer than 5 feet or there is a clog inside the hose connection. Possibly some packing debris. To solve the problem, do the following:

Turn the unit OFF and unplug it.
Disconnect the hose from the hose connection. Using an appropriately sized, 18" long, plastic Zip Tie, carefully insert the tip of Zip Tie into the hole or tubing. Continue to push it in until you reach a bend in the tubing. You will need to gingerly work the Zip Tie past this bend, until it either bottoms out or you run out of usable Zip Tie. Then slowly pull the Zip Tie back out while rotating (twisting) it. This will breakup any clogs. As you reach the inserted end of the Zip Tie, be prepared, as some water may follow. Reconnect the hose to the hose connection, plug the unit in and turn the Master ON/OFF Switch to ON. Set the humidity extraction level to 35% or Maximum if you have a manually controlled unit. Allow the unit to run for an hour, while you monitor it for any leakage or drainage into the bucket.

NOTE: If you don't have a Zip Tie, you may use something similar ( i.e.a long pipe cleaner), but NO wire coat hangers.

If it still doesn't drain thru the hose. Remove the water bucket and check the top for a float valve. It may be stuck in the UP position. If it is, jiggle it to make it return to the down position.

I hope this helped you troubleshoot and solve the problem.

SOURCE: Frigidaire Dehumidifier gives F2 error code and no longer runs.

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.
