Re: 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.

Norman, once the unit reaches the extraction level you have it set for, the unit will turn OFF automatically. However, depending on the humidity level in your home, it may take several cycles of running and emptying the bucket until it reached. After that, it should turn OFF, once the level is reached. Then when the humidity level rises above the setting it's on, it will start up again.
Since your unit is a Manually Controlled unit, there's no safe way to "rig' it to run on with a timer. The plug in wall timers are not rated high enough to handle the load of the dehumidifiers operation. Trying to use one, would fry the timer and possibly the dehumidifier.
If you want all the features you mentioned, you will need to purchase a new electronically controlled dehumidifier.
You may have the humidity level set to high. Usually anything above 50%, will show little results, unless your house is flooded.. Turn the humidity setting to the lowest level that your humidifier has and give that a try.
The fan runs a lot, because it's designed to almost constantly move the air around. That way, if the humidity level rises above the setting on the dehumidifier, it can sense it and the compressor will turn ON.
If you want to give it the ultimate in-home test. Put the dehumidifier in the bathroom with the door closed and a hot shower running, but do not turn on the bathroom exhaust fan. Set the dehumidifier's controls as low as possible and let it run for 20 minutes. After 20 minutes, return to the bathroom, turn the shower OFF and check the water collection bucket for water. The unit will probably be running anyway, when you return to the bathroom.
Remember, the lower the setting, the more the unit will run and collect water. Until it either reaches the humidity level you have it set for or the bucket is full and the unit automatically turns OFF
That's the best way to test a dehumidifier at home. Hope it helps you. Please let me know.
Probably not a part missing, Judy. It's likely that you have the humidity level set to high on the unit. Remember, the setting that you put it on, is what the unit will maintain, not remove. So, try lowering the setting to the lowest level and that may solve the problem. Also, if you haven't cleaned the air intake filter, since your kids returned unit, that will help too. But, before you do any of the above, turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet. Once you have completed the filter cleaning, plug the unit back in and turn the Master ON/OFF Switch to ON. Then set the humidity level to the unit's lowest setting.
Part of the problem may be that you have the humidity level set to high. The fan runs constantly to move the air around. When the unit senses a humidity level higher than what you have it set for, the compressor turns ON. Once it's ON, if the humidity level is short lived, it turns OFF.
Try setting the humidity level to the lowest possible setting. Usually, that 45%. If the humidity level in you home is higher than that, the compressor should turn ON and run until either the bucket is full or the humidity level reaches 45%. If this doesn't solve the problem, turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet for 12-15 minutes. Plug the unit bakc in, turn the Master ON/OFF Switch to ON and set the humidity level at it's lowest setting. Allow the unit to run until it cuts OFF and check the bucket for water. Hopefully that 12-15 minute time out allowed the unit to reset itself.
Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.
First, make sure the humidistat isn't set too high by adjusting it to
the lowest humidity setting and running it again. Next, test the
dehumidifier by placing it in a closed bathroom with a hot shower
running. If you don't see water collecting in the unit after several
minutes, turn the unit off and clean all dehumidifier filters and
coils. If, after adjusting the settings and cleaning the unit, you
still don't see water collecting, you may have a refrigeration issue.
This situation will have to be addressed by a qualified technician.
