Location & How It Works


Selecting a Location

  1. The dehumidifier must be installed on a level floor that will support it with a full bucket of water.
  2. There should be a minimum of 12 inches of clearance around the dehumidifier.
  3. Place the dehumidifier in a location that does not restrict airflow through the front of the unit or out of the louvers on the left side of the cabinet.
  4. A dehumidifier operating in a basement will have little or no effect in drying an adjacent enclosed storage area, such as a closet unless there is adequate circulation of air in and out of the area. lt may be necessary to install a second dehumidifier in the enclosed area for satisfactory drying.
  5. Dehumidifier must be operated in an enclosed area to be most effective. Close all doors, windows, and other outside openings to the room. The effectiveness of the dehumidifier depends on the rate at which new moisture-laden air enters the room.

How It Works

The coils condense or draw moisture from the air, and air flows through the top louvers into the room as dry, warm air. Moisture removed from air is collected in a bucket in front of the dehumidifier. When the unit is started, the fan begins to pull moisture-laden air across the dehumidifying coils. The unit is designed to operate between 41 °F (5 °C), and 96 °F (35 °C). The unit will not work properly if the temperature is out of this temperature range, or the performance of the unit will fall greatly. The “Compressor” circuit has an automatic 3-minute time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. Make sure the tank is fitted correctly otherwise the unit will not turn on. 

Operating Instructions 

Allow the unit to reach room temperature before operating. To begin operating the dehumidifier, follow these steps:

Unit must be upright for one hour prior to operating.

  1. Plug the power cord into a properly grounded 115-volt AC outlet
    If the “BUCKET FULL” light is on, remove the bucket and re-install to reset the float switch. Frigidaire Dehumidifier LAD504DUL FIG-1
  2. To turn the unit on, press the ON/OFF button. The unit will run in the factory setting of CONTINUOUS and high fan speed. In the CONTINUOUS mode, the unit will only display CO and not the room humidity. It is recommended you leave the unit running in the CONTINUOUS setting for the first three or four days until the sweating and dampness odors have stopped. Frigidaire Dehumidifier LAD504DUL FIG-2
  3. After a few days when the Relative Humidity has declined, press the HUMIDITY Frigidaire Dehumidifier LAD504DUL FIG-3 buttons to choose a value between 35% to 85%, so the room is kept at a comfortable humidity. Pressing the Frigidaire Dehumidifier LAD504DUL FIG-3 buttons will change the humidity selection in 5% increments. After you have set the desired humidity, the readout will display the actual room humidity. If at any time you want to return to the CONTINUOUS Mode, pressing the HUMIDITY V button will lower the Relative Humidity through the 5% increments until the display reads CO. Frigidaire Dehumidifier LAD504DUL FIG-4
  4. You can also use the FAN SPEED button to change the fan speed to HIGH or LOW. The indicator light will show the setting you have selected. A higher fan speed will result in quicker moisture removal. Frigidaire Dehumidifier LAD504DUL FIG-5
  5. The CLEAN FILTER light will illuminate after 250 hours of operation. At this time refer to the care and cleaning section to remove and clean the filter. Once the filter has been cleaned and replaced, simply press the FILTER button to extinguish the light.  Frigidaire Dehumidifier LAD504DUL FIG-6
  6. The TIMER function enables you to either Delay Start or Delay Stop the unit in the choice from 0.5 hour to 24 hours. If the unit is running, then selecting Timer will turn the unit off in the hours that will be set (Delay Stop). If the unit is off, then selecting Timer will turn the unit on in the hours that will be set (Delay Start).
    TIMER setting: First press TIMER button, then adjust timer setting, by tapping or holding the Frigidaire Dehumidifier LAD504DUL FIG-3 button to change the delay timer at 0.5-hour increments, up to 10 hours, then by 1 hour increments up to 24 hours. The control will count down the time remaining (8,7.5,7, etc.) until the unit either starts or stops. For the Delay Start, the fan speed and humidity maintained will be the same as previous setting. After TIMER setting finishes, pressing the TIMER button again at any time will stop the TIMER function. The Delay Start/Stop Feature will work until the unit either starts or stops. Once that happens the above steps have to be repeated.


    1. Before entering TIMER setting, make sure power is being supplied to the unit.
    2. Before entering TIMER setting, make sure pressing HUMIDITY or button sets one desired room humidity first.
      Frigidaire Dehumidifier LAD504DUL FIG-7
  7. To shut the unit down, press the ON/OFF button. Frigidaire Dehumidifier LAD504DUL FIG-8

FAQ’s Frigidaire Dehumidifier LAD504DUL User Manual

What does a Frigidaire dehumidifier’s pump button do?

When you press the PUMP button, the device starts to pump water. The indicator for Pump Mode will be on. The pump will automatically begin to pump water once the water tank is full. After the water tank is completely empty, the pump will shut off automatically.

What setting does a Frigidaire dehumidifier perform best in?

Here’s how to maximize the effectiveness of your dehumidifier. Set the relative humidity. According to Energy Star, the ideal relative humidity range is between 30 and 50%. (and 30 to 40 percent in colder areas during the heating season).

Does the Frigidaire dehumidifier shut off on its own?

When the correct amount of moisture has been removed from the air, the dehumidifier automatically switches off. If the humidity level rises above the specified setting, the compressor automatically switches back on.

How long should a dehumidifier run each day?

An energy-efficient dehumidifier should be used for at least 12 hours every day. You can do this to remove moisture from the air without using a lot of energy.

When a dehumidifier is full, do they turn off?

Yes, the majority of dehumidifiers have an automatic shut-off button that will activate either when the collection tank is full or when the designated humidity level is reached in your room. Your humidity settings or auto-shut-off feature may be problematic if your dehumidifier is overflowing.

What is a dehumidifier primarily used for?

Dehumidifiers remove moisture from the air. As a result, the growth of mold and dust mites is delayed. They are especially useful in areas of the house like damp basements where humidity tends to congregate. Dehumidifiers draw in air, run it over cold coils to condense out moisture, and then pass it over warm coils to let the moisture-free air back into the area.

What temperature ought my dehumidifier to be set to?

Temperatures at Which a Dehumidifier Should Operate. For refrigerant dehumidifiers, a temperature range of 70 to 90 degrees F is the best operating range.

Why won’t my dehumidifier from Frigidaire drain?

Make sure your drain hose doesn’t have any kinks, bends, obstructions, or other damage that could stop the water from flowing smoothly. Please make sure that the hose end is not lying in standing water if the drain hose has been routed into a drain, such as a standpipe or down into a typical sink.

Why isn’t my dehumidifier from Frigidaire accumulating water?

Your dehumidifier is not working properly if it is not collecting water: Attempt to reset the dehumidifier by unplugging it for 30 seconds, then plugging it back in. After that, adjust the unit’s controls to see if it works properly.

How much water can a dehumidifier from Frigidaire hold?

The Frigidaire® 50 Pint Dehumidifier has the following features and advantages: 50-Pint Per Day Capacity 16.9-Pint Water Reservoir.

How can the interior of a dehumidifier be cleaned?

Combine one part vinegar with one part water in a spray bottle. Spray the mixture into the tank of the dehumidifier. Before cleaning the tray with a sponge, scrub brush, or even a toothbrush, let the spray stay on the surface for a while. By utilizing a soft bristle brush to clean the grille, you can clean the filter and coils.

How often should I dump my dehumidifier each day?

To collect the water drawn from the air, every portable dehumidifier has a water collection container, frequently referred to as a tank or a bucket. To reduce the overall size of the dehumidifier, these buckets are fairly small and must be emptied at least once each day.

Should you use a dehumidifier during the day or at night?

Call your energy provider and inquire about the “optimal hours” if you’re worried about paying too much for your electricity. Between 10 pm and 7 am is typically the greatest time to use your appliance to save money because less people are using electricity during this period, which lowers rates.
