I don't understand how to set my humidifier to run economically and still do it's job.

First, I'm not a Frigidaire tech.

* 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.

What is wrong with it?

It sounds like the feed has been shut off or pluged. Be sure the feed is off, remove the feed from the humidifier. open the fill valve slowly and run water into a bucket or whatever. If it does not run you found the problem, if it does then it is probably the fill solenoid valve on the humidifier.

My suggestion is to get an additional humidifier and run both. It sounds like it is at capacity. This was a cold winter and the additional heating put a large demand on the humidifiers.

Is it only the fan motor running that you hear? Or is it the compressor motor and the fan motor in combination?

If it's just the fan motor, it running to circulate the air, in an effort to sense humidity in the air, above the level you have the humidifier set on. Speaking of which, you may have the level set higher than what the humidity is in the house and the unit is just maintaining it. 50 to 60% is high, as opposed to 35%, which is what most folks want to maintain in the hot, humid, summer months.

If you want to test the unit, place in the bathroom, turn a hot shower ON, turn the humidifier ON and set it for 45% or minimum if your unit does not have a LED readout screen. Do Not turn the bathroom exhaust fan ON. As you leave the bathroom, close the door and don't return for 20 minutes. When you do, turn the shower OFF and check the humidifiers water collection bucket. If you see any water, the unit is working as it should. If you don't see any water, it's time to replace that unit. I say that because, at best, the parts and labor to repair the unit would be equal to or almost equal to, the price of a new dehumidifier.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks

Hello,

If there's no water in the reservoir, first make sure that water is getting to the humidifier. The humidifier must have a good stream of water available to it. If there's water in the water line but the reservoir doesn't fill, replace the float mechanism inside the humidifier.

Take care.

Hi,

Here is a tip that I wrote that will help you understand why and what you cando with a dehumidifier that ices up.

Dehumidifier is Freezing up and not working

try checking the setting of your humidifier, if the actual humidity level matches, what is set on your unit.

RH at 70 % seems to me a little excessive you really should be working somewhere around 50 to 56% the fan has to move Air through the system.
I would like to know your room Air temp what is the Air temp comming off the system. what are your parameters.

Running a dehumidifier when the ambient temperature is to low will cause freeze-ups. Also running it when the dew point of the moisture in the air is to low will cause it to freeze up when you set it to low which would be a higher number on the set point.

The hand written number on the probe casing is probably a quality control inspector number.
