Question about Kenmore Dehumidifiers
I bought a kenmore 70 pint dehumidifier. At 60 to 65 degrees average temp and about 55% relative humidity, I set it to work toward a limit of 40% relative humidity. It works at first for about a couple hours, and then stops pulling water out of the air even though the compressor continues to operate without significant pause. I then leave it off for the night and return to find the 22 pint bucket one fourth full. It seems that the moisture is frosting up into a large block of ice around the coils. This model (99701) says it has an auto defrost feature that turns off the compressor and uses the fan to melt ice. I returned the dehumidifier to sears for another one, thinking it was defective. However, the replacement is doing exactly the same thing. Am I doing something wrong? At the very least, lower operating temperature should cause the unit to work inefficiently as the compressor is put on hold periodically to defrost. The defrost doesn't seem to be working at all and the coils seem to be too cold (frost builds up VERY fast). But for both brand new units?
Unless equipped with special equipment most dehumidifiers will produce little if any water under 65-70 degrees. Many state operation down to 50-60 degrees but this was under lab conditions and therefore a marketing tool. The best performance is gained when the air temperature is above 70 degrees. The water you are finding is from melting frost, if you have a humidity problem you should be adding heat to the area to be dried, warm air holds much more moisture than cold and drying is much more effective if you can heat the area to around 80 degrees.

Thermostat or the temperature control module are not working properly. Also make sure that your fan blades are not broken or warped as this will cause you a problem. Also if the coils have or do get iced up then it will be a low coolant problem. But this is a thermostat or temp control problem

SOURCE: Dehumidifier Error?
Same problem with Goldstar model DH404EY7 -- stop code 01 on startup, bucket full light blinks (drains to floor).
Replaced the main controller board to fix it.
For my model dehumidifer the part # is 6871A20888A, and cost $77.44 (not counting shipping) from Appliance Factory Parts. The Appliance Factory Parts web site also provides parts breakdown (exploded parts diagram) diagrams and service manuals in PDF form.

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

SOURCE: Dehumidifier Freezing up
Your dehumidifiers are LOW on freon. Over time, small leaks will occur and the coils will freeze. Take your units to a qualified repair shop (central air, or furnace) and recharge the freon.
