This model furnace does not come with a built in humidifier. Humidifiers are normally an optional add on. If you have a by-pass type humidifier it is none adjustable. Water level is normally float controlled and operation is control by blower circuit. When ever the blower runs the humidifier operates when in the heating mode.

Hello, why does my dehumidifier goes on and off every 4 minutes, last year was working fine, started the machine last week ans now it goes on and off, thanks

Most dehumidifiers work on a thermostat, and yours probably got turned down. You might look on the top and see if there are any knobs and try to adjust it that way.

How do i replace the humidity sensor

Only two wires and two screws. Shut off the furnace disconnect switch before doing anything. Then Pull off the cover and I do mean pull off. Then undo the two screws remembering what terminal they go to. Remove the screws from the back plate and let the wires fall through the back plate as you pull it off the wall or duct. Put the new back plate in place with the wires pulled thought. Install the screws I the same place as the old ones. Re attach the wires into the same labeled terminals as the old one. Put the new cover on. Turn on the furnace disconnect switch and away you go. To check operation all you need to do is, turn the knob on the humidifier control and listen for the solenoid to open and water to flow to the humidifier. If nothing happens then you need to check for power to the humidistat. Should be 24v. If no power then you need to check the source.

good luck

Dehumidifier runs continuously and displays higher than normal humidity levels.

Probably some glitch with the sensors. I recommend taking it to a service center.

Water overflows when filled how do I adjust?

Remove the tank and locate the switch and 'teeter' (that the tank sits on). Make sure the tank is able to move when filled. You will have to adjust the position of the switch to allow the filled (teetered) tank to shut the device off.

Is it possible for you to drain the water into a nearby floor drain using a hose?

Thanks for your question @

My new LG "ld450eal" DeHumidifier

The switch that says 'Bucket is full' is not adjusted properly.
It will need to be adjusted, normally a screw driver or pliers,
so that when its empty the switch is not made or the contacts
are open.
If it is in adjustment properly, then the switch is bad and needs
Before you replace it, check to make sure the wires leading to it
are not touching, it may be sending a signal meaning 'full' by
electricaly touching each other at the switch.

Dehumidifier only runs for a few minutes then turns off. Model# AHG30

there is a knob on the machine that sets the level of humidity. it sounds like you need to adjust it to remove more humidity from the air before it shuts down.

Maytag electronic dehumidifiers full light stays on

Take out the bucket and locate the "full" switch in the upper right of the area where the bucket slides in. With the unit on, try pushing it in and see if the "full" light goes off.
If so, that switch is fine - if not try to adjust if and replace it if required. Those are generally micro-switches and firms like Radio Shack would have if your appliance parts dealer does not.
