I have a frigidaire FRA186MT2, it cools great but does not remove humidity. What causes this?

air conditions work by removing the humidity from the room air
very humid air will cause a lot of condensation in the evaporator section especially if you have it set below 25 c
keep all doors and windows closed to prevent fresh air bringing in more humid air as that makes it hard for the ac to work efficiently

probably the ac section to cool the humidifier is not working
for a de-humidifer to work there has to be a cold surface to condense the water vapour in the air
if there is no ac unit ,it will still need that temperature difference to work or a sufficient humidity in the air to work

If moisture/water gets to the control board it will/may cause it to act this way. Or the control board may have a short. It may also have a bug, mouse, or gecko laying on the controls. Something causing it to "misfire" or short. If a visual inspection does not show evidence then its probably control board failure.

Look at the drain tube that goes between the evaporator side into the condenser side for obstructions if water puddles up on the bottom of the unit. Make sure the inlet air filter isn't plugged up too.

Hi Ra Ma,
After you have set the desired humidity, the readout will display the actual room humidity. It has a built in hygrometer which will be on the display while it is running.
You change it and it shows the actual levels.

See page 5 on manual.

AC units, no matter if they are big/small, window or big central units. They will only cool the air in the room, or home, to about 15 degrees cooler than the outside air temperature. If you live in Georgia and it is 100?F+ outside, you will be lucky if the unit will reach 80?F even running all day.

If you just plugged it in and started it up, you may have failed to set the humidity extraction level. Which is different from the factory settings. If you want to remove great deal of humidity, lower the setting to 35%. Keep in mind, the lower the setting the more humidity/moisture will be removed from the household air. The higher the setting less will be removed.

As far as the unit beiing warm is concerned ... Be sure to maintain at least a minimum of 12" clear air space all around the unit while in operation. Do not operate the dehumidifier in direct sun light.

Also, make sure all the packing material has been removed from the interior of the unit. This will block the airflow and cause the unit to overheat. If it does overheat, it should shutoff automatically. But, don't confuse that with normal automatic shutoff (i.e water collection bucket full, timed cycle has ended, no more humidity to remove from the air, etc.)

When all else fails, consult the owner's Manual.

Hope this helped you. Please let me know.

Hi Brian,

I recommend that you set the freezer to a WARMER setting to avoid getting ice on the back of the freezer. The ice is preventing good air flow over the cooling plate and therefore is not keeping the items in your freezer cold enough. You will need to remove the ice - which can be a daunting task. If you are able to store all your frozen items somewhere else for a while, it would be best to let the whole thing thaw out. I can't find any specs on that fridge, but i would guess that it does not have an automatic defrost, which is, in part, what is causing your problem.

If you are in a humid climate this will happen more frequently - especially if you have the unit outdoors or in an unairconditioned area.

To be honest with you this is a good and a bad thing. The bad thing is that it is spitting water into the room. The good thing is that the unit is running Great. The amount of humidity it is removing. is greater and faster than it can run down and off the coil. See if there is any possible way to deflect the water. i would recommend trying to attach a piece of screen door material. It will likely keep the water from going through it.

Just adjust the thermostat lower or colder!
