To remove the back cover, first remove the sides: two screws at bottom of side, one halfway up the back, one inside bucket opening. Also remove four screws holding the top on. Top slides forward to release, then sides slide up about 1/2 inch and pull straight out. Hooked into the front and back. Once the sides are off, the back will come off with remaining four screws.

* The humidifier will only run if the "Humidity" (water or moisture in the air) is higher than the current setting on the humidifier. If it's set to maximum dry setting then expect it to run almost 100% of the time. If it is set to a "wet" setting then expect it run only for short periods.
* Colder room temperatures will reduce the frequency of cycles as cold air will hold less moisture than warm air.
* You may note that running a AC unit in the same room as the dehumidifier will give you mixed results as both units will "fight" or work against each other. Humidifier will heat the air as it exits while the AC will cool the air. Best to not run the AC while the dehumidifier is in operation.
* Note that AC do "dehumidify" the air as it passes through. But not as effective as a dedicated dehumidifier.
* Be sure to check the tub and filter (make sure they are seated properly.)
* Contact Frigidaire or your local Appliance store for service.

* Most dehumidifier components are similar to a standard small refrigerator. Except for a large fan (with corresponding fan noise). It should sound the same but running more often than a refrigerator.
* A dehumidifier is mainly used to remove or control humidity in a specific area. The most common use is to dry carpets or a damp basement.
* Though high ambient humidity (as in Hawaii). Expect the unit to run all the time as moist air seeps into the area.
* Typical noise from older units (but still working); https://www.youtube.com/watch?v=dwsqgM3KI28

Usually that is a sign that your dehumidifier is low in coolant. Could be something more serious, but usually would require to be charged back up (and sealed to prevent coolant from leaking out).
