I have had my Kenmore 52450 for 3 years now without a problem. After setting it up recently, it runs all the time with the coils and evaporator icing up. Bucket will never fill I have cleaned unit with no success of eliminating condition. Any ideas?
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.

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
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
My first thought is that there's not enough moisture/humidity in the air, for the setting you have the humidifier set on. The higher the setting or percentage (i.e. 60%) means that the level you want to maintain. Which may be find in the cod winter months. In the Hot summer months, you want as low a level of humidity as possible (i.e. 45%).
My second thought is that the air intake filter and the coolant coils need cleaning, since it has been used in 2 years. It's just sat around gathering dust and spiders.
And finally, the collection bucket, may not be inserted properly and when the unit starts up the vibration dislodges the bucket just enough, so that it's not making contact with the safety switch. Sometimes when this happens, the Full light indicator will come ON, even if the bucket is empty.
Hope this helps you to start troubleshooting the problem. Please let me know.
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.
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.
