The frost is requried for the unit to do it's work. The unit should routinely turn off and the ice should melt. without this process no water would be removed from the air....

The best thing to do is keep the filter clean. When it's dirty or clogged, the unit has to struggle to keep up. The frost develops on the coils. You must also consider the temperature of the basement. If it reaches 40 degrees the dehumidifier will stop collecting moisture.

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-

When the compressor is running, should the fan also be running??


yes
whenever the compreesor is running you ned the fan to run for two reasons
1 to cool the compressor
2 to sling the condensate on to the evap to keep that from building up frost

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).

The coils frost up for Kenmore dehumidifier model 580.53701300 even the temp is > 70. the fan works fine. there is a few water in the water bucket. the humidity> 65%.


check the drain tube for blockage, maybe run a small rubber hose to clear out blockage so condensation can drain freely. Worth a try worked for me

Haier Dehumidifier stuck on 45


Check the coils at the back of the dehumidifier to see if there is any frost buildup on it. If there is, turn off the machine for a while until the room warms up and melts off the frost. The machine works by condensing the moisture in the air over these coils, so if the coils are frosted over, or are not cold enough, the moisture cannot condense. If the coils are not cold enough, you may want to get it refilled with refrigerant. You will need to take it in for servicing in this case.

Hope that helps! Should you have any further questions, please feel free to post them here.

P.S. - If you find that the solution/answer I provided led you to, or resulted in a fix, please close the ticket with a FixYa! rating. I would be very grateful for your show of appreciation.

Thank you for using FIXYA!

Dehumidifier freezes up


Most dehumidifiers need warmer air to work properly. The temperature in a basement is usually 60 - 65F; too cool for standard models. You could buy a "basement" dehumidifier. They're designed to work at lower temperatures; some as low as 40 F. Costs are about the same as a standard dehumidifier; you just have to find it.

For a cheap fix, try this; it seems to be working for me.

Since the condensate coil (the one icing up) is cold, the air entering it is too cool and the condensate frosts up the coil. Additional condensate freezes to the frost and before you know it, you've got a block of ice. Since the air coming out of the front is very warm take a large piece of cardboard around 6' x 3') and form a V. Placed it in front of the dehumidifier so it channels some of the warm air back to the rear where it warms the moist air up before it hits the cooling fins. It's helped keep the ice down.

If you want something attractive, any screen that redirects some of the air back to the rear will work. Just leave the top open so it doesn't get too hot and the some of the drier air gets out into the room.

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

Thank you for your allowing me to advise you on this issue.
