Compressor does not shut off, ice builds up on coils rather than water draining off.
Good Afternoon Friend,
I understand your Frigidaire dehumidifier, model# FDF50S, is freezing up. I see that the compressor does not shut off, causing ice to build up on the coils, rather than water draining off. What can cause this is your dehumidifier has been turned on recently. This is normal due to refrigerant rushing through the coil. Frost will usually disappear within 60 minutes. Another cause is if the room temperature is too low or too high. Your appliance is designed to operate between 41 degrees F and 96 degrees F. I suggest resetting your appliance, by either unplugging it or shutting the power off at your home's circuit breaker, for 3-5 minutes. Restore power and start any cycle. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.
-Best Regards-

Your dehumidifier may be low on refrigerant. Seems cold may not be cold enough to reach the dew point to condense moisture from the air stream.

Nothing worked, because the drain hole to the hose connection is clogged or the hose is clogged. When that happens, water is diverted to the bucket.
Turn the Master ON/OFF Switch to OFF & Unplug the unit.
Remove the hose and check it for clogs. If none are found, the clog is inside the hose connector.
Using an 18" long plastic Zip Tie appropriately sized to fit the hole. Carefully insert the tip of the Zip Tie and continue to push it in, until you reach a bend in the tubing. You will have to gingerly work the Zip Tie past the bend, until it bottoms out or you run out of usable Zip Tie. Then slowly remove the Zip Tie while rotating (twisting) it. This will break up any clogs. As you reach the inserted end of the Zip Tie, be prepared as some water that might follow. Even if you don't see any residue from a clog, it may have been pushed out of the way. Reinstall everything, plug the unit in, turn the Master ON/OFF Switch to ON and take it for a test drive.
Be sure the hose is no longer than 5 feet and that it gradually slopes down and away from the unit. The water drainage relies entirely on gravity.
Hope this helped you troubleshoot and solve the problem.
