Re: Coils Frost up and Bucket never fills

Poston192: You have a refrigerant leakeage in the unit, that's why it's frozen up. If you want to do it yourself, here's what to do: 1. Disconnect power from unit. 2. Remove covers from dehumidifier and locate coils and evaporator units inside. 3. Check for greasy or sticky signs on joints and weldings. 4. Once locate it, re-solder (in case of leakage on weldings) or adjust very tightly the joints. 5. Reassemble and test. SithPitt

My Kenmore dehumidifier isnt working. Clean filter and back. Frost on top of the dehumidifier. The round black cylinder- compressor is hot.No water in the bucket.

signs of frost on your machine is an indicator that (1) there's not enough air flow over coils
and (2) there has occurred a leak in your system and some or all of the gas has escaped out to the atmosphere

number 1 usually causes number 2 due to increase in heat

unplug for 48 hrs then try it again if no joy then you'll need to replace it

Why does Frigidaire dehumidifier LAD704DUL has ice on the coils?

Hello Friend, thank you for your question!

I see that you have frost accumulating on the coils of your Frigidaire dehumidifier, LAD704DUL. Typically frost appears on coils either because your dehumidifier has been turned on recently or the room temperature is too low. Sometimes this is normal due to refrigerant rushing through the coils and usually it disappears within 60 minutes. However, if your dehumidifier is not removing moisture, then at this point your dehumidifier may possibly been experiencing a sealed system issue. Is your appliance still in warranty? If so, you might want to reach out directly to the manufacturer to determine the coverage on your dehumidifier and the procedures to any potential remedy in that regard. Hope this helps! - Z

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

Frigidare Dehumidifier will not turn off

Pressure and temperature is directly related with refrigerants in the system. Ice building on part of the coils shows that the pressure inside the system is low and the system has lost some of its charge. Very low humidity with a low ambient temperature will also cause such a problem.

Does not collect water

ok Carmo

first remove the back of the unit and turn it on. it sounds like the fan motor may not be working.there by making the dehum get hot. make sure your filter and coils are cleaned. you may need a new motor. if so buy a new motor and fan careful with the 5/16th nut holding the fan blade. the blade might look good but you have to check the hole where it rides on the motor shaft. if you into the hole it should look like the letter "D" because the motor shat is shaped that way.---good luck

Power lose

I have a 45 pint. I have to slide the bucket in and out of the unit multiple times. Make sure to wait a few seconds after each time to see if it will recognize no water (sometimes the red light comes on, but then changes it mind). Also, I've found that leaving the bucket a little crooked will make it respond. It sucks, I know. Mine is only a year old too. Should not be a problem like this!

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.

Dehumidifier does not collect water.

My unit does not collect water any more. It was fine until I lent it to my brother in law and it was returned damaged. Do you know how to fix this
