First, make sure the rectangular filter on the back side is clean so air can flow over the coils freely. Try to place the dehumidifier on a table or something to get it off the floor. (floor level is cooler than head level) If you still have icing issues, replace sensor. (part # WK23X10011 )

SOURCE: Dehumidifier Freezing up

Your dehumidifiers are LOW on freon. Over time, small leaks will occur and the coils will freeze. Take your units to a qualified repair shop (central air, or furnace) and recharge the freon.

My dehumidifier ddr557he will no longer defrost. How do I repair this?

well there are three things i know of that can cause this :
1st your filters are dirty needs cleaning .
2nd your humistat is set too low , unit runs too long with out a cool down period , 70% rh is a "normal" setting
3rd in older units that might be getting up there in years its possible that some of the cooling gas has leaked out and this causes freeze ups

Ihava a dehumidifier MOdel#106955250. The coils are icing up, can you help me?

as with any freeze up of any unit (any mfg) there are a few things to look at first before consulting a profesional ,
1st ck your filter most units have a filter these are the most forgoten things when it comes to reg cleaning , remove it and run under tap shake excess water off and replace in unit
2nd is unit warm enoght to work air temp has to excede 68 degrees for these to work
3rd how old is unit if unit is over three years and has been largely neglected for cleaning and maint issues then overheating can cause gas charge to leak out and cause freeze ups , replacement is only option on this reason
4th setting: is unit large enoght to remove water from area if its undersize it runs too hard and never cycles off/on this causes freeze ups , purchase a small humidmeter to measure the area % rh 70%rh is considered normal for a home

Dehumidifier does not reduce humidity.

Good Afternoon Miguel,

I understand that your Frigidaire dehumidifier, model# LAD704TDL, is not reducing the humidity, due to the coils constantly freezing up. I also see that it is located in good temperatures and in a good position. I suggest contacting the manufacturer directly. They should be able to point you in the right direction to having your appliance fixed. Hope this is helpful.

-Best Regards-

MY unit keeps on freezing up no problem with the filter dirty it gave me a problem after 3 months of use . i set it for 60% 50% it freezes up all the time i shut it off let it defrost and same thing all...

I think a part of the problem is that you have the humidity extraction level set to high. 50 to 60% is pretty much the humidity level throughout most of the year. Lowering it to 35%m should make a difference.

If you are using this in a basement application, the temperature at floor level can be 10 degrees cooler than at shoulder level. Most dehumidifiers don't work well at temperatures between 40 & 60 degrees F. Unless, they are Low Temp models designed for basement applications. Raising the unit up off the floor onto a sturdy table, counter top, etc. That can handle the weight of the unit, plus a full tank of water can resolve this problem.

If you can access the cooling coils, they may be dirty and need wiping off with a damp rag. Then flow with a dry clean rag to dry them. A light coating of WD40 helps to preserve the coils.

I hope this helps you to further troubleshoot and solve the problem. Thanks for choosing FixYa.

My Frigidaire dehumidifier model FDL70S1has an error code "A5" My coils keep freezing up as well with heavy ice. It has worked fine in the same spot in the basement for two years until last week....

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.

Coil Freezes up. Filter Clean. Temp is low 60s.

Unless you have special model, that's what happens at 60 or less. defrost over a drain (it won't run into the bucket) and move to wamer location or face a electric space heater 2-3 feet from it

Based on the information provided above, I am unable to provide a positive solution to your issue. I have provided some common solutions to help guide you in your search.

This link,, provides exploded view imagery, belt routing diagrams, parts imagery and function, parts ordering and shipping information, error code details, just about anything you need to get your appliance up and running again. Just follow the links to navigate through the site.

You will need to enter the model number stamped on the manufacturers product information data tag, located on the unit, and not in the User’s Manual. to access your product information.

Clicking on the underlined links will take you directly to that page.

Note: A volt-ohm meter is beneficial in performing electrical tests.

Some models utilize a defrost thermostat that simply switches the compressor off and on. This can be replaced by unsnapping it from the condensor coil.

Another type uses a defrost control kit to cycle the compressor and is a little more involved in the replacement.
