Are sure the bucket switches are not stuck in the full bucket position.
Cleaned the cooling coils.
Verified that the controls are set for a low humidity
Verified that there are no trouble lights or codes,
Know that the area to be dehumidified is well above freezing..
It sounds like they are both stuck in defrost mode or the compressors overheated and need to cool off. "Both" is a bothersome word. Both might imply a power surge that wiped out the controls. I would:
Unplug them and let them cool off 36 hours.
Check your manual for a control panel reset.
Take off whatever covers I could, to let me touch the cooling coils to be sure they get cool.
Plug in # one and reset the panel.
Let it run and see if the coils get cold.
Plug in # two and reset the panel.
Let it run and see if the coils get cold.
And then decided what to do next. Hopefully the cool off and reset did it .

well if the unit has never been taken apart and cleaned well inside, and it's five years in service , Id say thats your problem, anything thats got room air blowing thru it for five years ,It's gonna need to be tottaly cleaned in all areas
Good Afternoon Tad, thank you for allowing me to assist you!
First remove the bucket to reach the filter of your Frigidaire dehumidifier, FAD504DUD. When you locate the filter, pull it downwards. The filter can be clean by either washing it with clean water or using a vacuum cleaner extension hose. If you use clean water, please allow the filter to dry. Once the filter is reinstalled then replace the bucket. To extinguish the light simply press the FILTER button and your dehumidifier will resume normal operations.
There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. 1. The humidity extraction level is set to HIGH. Lower it to 32-35%.
2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the Unit, before removing to inspect & clean it, if necessary. If washed, allow filter to completely dry before reinstalling. DO NOT operate the unit without the filter.
3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.
4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.
5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures (Unless, you have a Low Temp Unit). This applies mainly to where the air
temperature at floor level is colder than at shoulder level in basement applications . Raising the unit up off the floor, onto a sturdy table, counter top, etc, that can handle the weight of the unit, plus a full tank of water, will usually resolve this problem.
If
none of the above solves the problem, it may be a case of the
compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are
5 years old or older. It's rare in a unit younger than that. But, it
can happen.
Hope this helps you to troubleshoot & solve the problem.
Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier
A dehumidifier works just the way an air conditioner works
but in a reverse manner. If you encounter a problem with your
dehumidifier then it would be repaired the same way you would repair an
air conditioner. As such a dehumidifier does not require much cleaning
apart from changing the filter.
When the filter and coils of the dehumidifier are choked with dirt,
it may not pull out moisture from the air properly. The efficiency of
the dehumidifier gets decreased and the only solution is, to clean it
thoroughly. In order to assist you with the cleaning procedure of a
dehumidifier, following are a few tips:
Remove the water tank/container and clean it after
draining the water. Depending on the usage the container must be
cleaned regularly.
Cleaning or changing the filter is also important for the main function
of ensuring a healthy atmosphere is performed by the filter. Mix some
bleach with warm soapy and clean the filter. It will help to get rid of
the bacteria, molds and mildew.
Use a vacuum cleaner to clean the evaporative coil/hot coil. Scrub off
the dirt using a brush but make sure that you don’t bend the fins while
cleaning.
Clean the condenser or the cold coil the same way. If the humidifier is
working in a room where the temperature is below 60 degrees Fahrenheit
then check the coils whether it is not icing up.
See to it whether the fins are bent or not, if they are bent then
straighten them out using a fin comb otherwise it might obstruct the
effective working of the dehumidifier.
And yes do not forget to clean the fan blades and other parts of the dehumidifier.
Keeping in mind the humidity level of your room, sets the humidistat of
the dehumidifier as keeping it too low or too high may only make the
dehumidifier to run longer than necessary.
Also before you start with the work of cleaning the dehumidifier, make sure that it has been unplugged.
