Condensation on frigidaire dehumidifier turn to ice

Good Morning Friend,

I understand that the condensation is turning to ice on your Frigidaire dehumidifier, model# LAD704TDL. This can be a possible cause of your dehumidifier being turned on recently. This is normal, due to refrigerant rushing through the coil. Frost will usually disappear within 60 minutes. Another possibility is the room temperature is too low. All dehumidifiers will operate satisfactorily at temperatures greater than 41 degrees Fahrenheit. 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 dehumidifier status has changed successfully. Hope this is helpful.

-Best Regards-

The top of the unit has alot of condensation on it. so i am wondering if its freezing up inside. Have set point at 55% what can i do to fix the issue

A little condensation is not something to worry about. But, a lot can be caused by a dirty or clogged air intake filter. Which can also cause the cooling coils to freeze.

Turn the unit OFF & unplug it, before removing the filter for cleaning.

Also, maintain 12" to 18' of clear air space all around the unit.

If the unit is in an extremely moist or damp environment, 55% is not really a low setting. 35% would be more appropriate for this type of environment.

Hope this helps you to troubleshoot and solve the problem. Thanks for choosing FixYa.

If on the top you mean only at the top of the cooling or condensing coil the machine could be low on refrigerant.

How to fix dehumidifier condenser won't start

That's your compressor. (the condenser is the tubing just after the compressor) First, make sure you are not using an extention cord, or if you do, make sure it is a heavy enough cord. Low voltage can cause your problem, do to a light extention cord use. Second, you may have a bad relay. (inside the box on the side of the compressor) Third, your compressor may be bad. They can be direct tested with a compressor test cord by a service tech that knows what they are doing. Bad compressor = get a new dehumidifier (too expensive to replace).

Dehumidifier frosts up

A dehumidifier will often frost up if room temperatures are colder than about 65 degrees F. If your room temperature isn't this cold, airflow to the unit may be restricted or blocked entirely. 1) Be sure the unit is set far enough from the wall so that airflow isn't restricted. 2) Clean the evaporator coils. To do this, unplug the dehumidifier and take off the outer cover. Allow excess moisture to evaporate from the coils. Then, using a brush attachment on a vacuum cleaner, remove all dust buildup. If necessary, cover the motor and electrical parts with plastic sheeting and spray with water.
