Question about Frigidaire FDL50R1 Dehumidifier

Open Question

I have an error code A5? My coils keep freezing up as well? What do I need to do? I have let the unit thaw and started it up again and the coils froze again. I tried cleaning the coils better after thawing it for a second time and I still have the A5 error code. I was just wondering if there was anything I could do or where I could take it to get it repaired as it's only a little over a year old.

All most all dehumidifiers have a defrost cycle to take care of this problem. However, yours is either not working or the air intake filter is clogged, which makes the unit strain to keep up. Turn the Master ON/OFF Switch to OFF and unplug the unit, before attempting to remove the filter. Allow the unit to thaw while it's unplugged. Once it's completely thawed, plug the unit back in, turn the Master ON/OFF Switch to ON and set your controls as you normally do. Within in an hour or two, you will know if this solved the problem. Also, keep in mind, dehumidifiers are designed only to work in temperatures above 41 degrees. If it's below that where you have the unit, that will cause it to freeze up.

With all that said, what you're seeing as the Error Code is in fact, AS (the 'S' looks a lot like a 5 on the LED screen) It indicates a Sensor Failure. In your case, it's more than likely the Defrost Cycle Sensor. The Owners Manual says "Contact your local Authorized Frigidaire Service Center, if this happens. I'm hoping that cleaning the filter (if needed) and allowing the unit to reset itself (while it's OFF & Unplugged) will solve the problem. But, it may only be a band aide fix.

Hope this helped you.

Zenith dehumidifier is freezing up on the front near the air intake.


check to see if the fan is working. low or no air flow will cause it to ice up. may have to remove the front to de-ice. turn the unit off and slowly pour warm water over the coils to thaw. the water should drain right into the bin. also good to clean any dust off of the coils to keep the air flow open.

Dehumidifier is Freezing up and not working


If you are having problems with your dehumidifier freezing up them here are a few things that you can check and also a few things that may help you.

First check the ambient temperature of the room at the level of the dehumidifier. If it is below 65 degrees and you do not have a special low temperature dehumidifier then you are asking for trouble. Most units are only designed to work in temperature 65 or higher and will freeze if they are working at lower temperatures. Some even will not work well below 68 degrees F.

Many dehumidifiers will shut off when the coil starts to freeze to let them thaw, then they will restart when the coil is warm enough again. This can take an hour or so. Some will not shut down the compressor and when the dehumidifier coil starts to freeze it reduces the air flow and only compounds the problem.

Check the air flow over the coil. If the coil becomes dirty or the fan motor stops or even slows down a bit, you will get freezing. The dehumidifier is very dependent upon the proper amount of air going over the coil to keep the coil warm enough to not freeze. Any restriction will cause problems.

The final and worst thing that can happen is for your dehumidification unit is to develop a slight leak in the refrigeration system. This will cause the coils to run even colder then they would normally and this will create the same problems. If everything else check out then you may have to have the refrigeration system checked by a professional. The problem with this is that many of these units only cost a few hundred dollars and a service call can soon add up to more then the unit is worth.

Some things that you can do to help out a dehumidifier that is freezing up are:

Raise the temperature of the room and provide a bit of heat for the room as the dehumidifier is actually a very small A/C unit.
Raise the dehumidifier up off of the floor… the air is usually warmer when you go higher up in the room, hot air rises.
Clean the coils off so that the air can flow through them easier and keep them warmer.
Make sure that the fan motor bearings are oiled and that the fan is running freely. Even a tiny bit of resistance will slow the fan enough to make a difference.


By checking all these things out and making some small changes you maybe able to make your dehumidifier work much more effectively.

Displaying "A5"


Do you mean error code AS instead of A5? If so, error code AS commonly refers to a sensor issue. Because it is a smaller appliance, repairs are often more costly than the actual unit replacement. You may want to check and see if your dehumidifier is still under warranty and if so, reach out to the manufacturer to determine the exact warranty coverage.

Coils freeze up. completely blocked. have to shut off to thaw coils. located in basement.


After the unit is totally thawed and dried, turn the unit Off if you haven't already and unplug it. Remove the filter and clean it. If it's really dirty wash it with warm water and dish washing liquid, thoroughly rinse it and allow it to completely dry, before reinstalling. DO NOT operate the unit without the filter in place.

Because the air temperature in a basement is colder at floor level, than at shoulder level, this caused the coils to freeze. Dehumidifiers do not work well at temperatures at or below 60 degrees F. That is, unless, it's a Low Temperature model, designed especially for basement applications. Obviously, yours isn't a Low Temp model.

To overcome this, place the unit up on a sturdy table, counter top, etc, that can handle the weight of the unit, as well as a full bucket of water. The higher off the floor the better. This way, the ambient operational temperature will be higher and the coils will have less of chance to freeze again.

I would suggest that continue to monitor the unit and if you notice that it's doing more than a little frosting on the coils, turn the unit OFF immediately. A little frosting is normal and the deforst mode should kick in and thaw the coils. When this happens, the compressor should automatically shut OFF, but the fan will continue to run. Once it's defrosted, the compressor will start again, if necessary.

I hope this helped you to troubleshoot and solve the problem. Please let me know.

DEHUMIDIFER COILS FREEZE OVER, WHETHER MACHINE IS RUNNIG ON LOW OR HIGH. FILTERS ARE ALL CLEAN.


Turn the Master ON/OFF Switch to OFF, unplug the unit and allow it to thaw out completely. You may want to put some old towels under it, to absorb the dripping water. Once it has completely thawed, remove the bucket, the air intake filter and the face of the cabinet. You should now have access to the coils. Clean them with a mild soap and warm water. Rinse and thoroughly dry the coils. Once they are totally dry, spray a very light film of WD40 on the coils and then wipe off any over spray. Reinstall all the remove parts and test the unit.

Keep in mind, if you are using the dehumidifier in a basement, the air temperature at floor level is colder than at chest level. Dehumidifiers don't work well between 40 & 60 degrees F. (Unless, they are a low temp unit). Any lower, the coils will freeze. Raise the unit up off the floor onto a sturdy table or counter top, that can hold the weight of the unit plus, a full tank of water. In a basement application, doing usually solves the problem of freezing coils.

If after doing all the above, the coils still freeze during operation, the compressor may below on freon and needs to be recharged. Or the defrost sensor on the unit, needs to be replaced.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

The fan runs, but we get an A5 error.


I think what you're actually seeing is an AS error. It's looks like A5 on the LED screen.
AS error means their is a sensor failure. So, before calling Frigidaire Tech Service
(800-444-4944), turn the Master On/Off Switch to OFF. Unplug the unit for 12 - 15 minutes.
This should give the unit ample time to reset itself. Plug the unit back in and turn the Master ON/Off Switch to ON. Now, set your controls as you normally do. If the unit starts up and runs as it should, the problem for now is solved. If it keeps re-occurring, contact Frigidaire Tech Service.

Iced up coils and will not dehumidify


I did a little digging around on the internet and found out that if the basement (or where ever you have your unit) is in an area where the room temp might dip below 65 degrees the coils may start to become "too efficient" in pulling the moisture/humidity out of the air and it begins to freeze on the coils before it can drip off into the reservoir. The site said to turn off the unit and let it thaw out, then restart it and see if everything works ok after that. If the temperature gets too low you might need to warm up the air in the room/basement before it will operate correctly again/not continue to freeze up. Hope this helps. Mine just did the same thing but we've had some pretty cold weather recently and the basement is fairly cold as well.
