We've had this unit for about 4yrs and loved it so much, bought a second one for another room. This past fall, we shut the unit down for the season. We went to start it up again today, plugged it in and .... NOTHING. The unit would not turn on. Is there a reset button or any suggestions? We've tried different outlets around the house with no success. Hoping you can help.

Be Safe or don't do it....

On the side with the lint screen, remove the five screws holding the top panel in place. The sensor that needs to be checked in mounted on the radiator fins. Remove the sensor and 4 pin connector. With a pin, remove the loose fitting housing the "sensor"...a circuit board that "shorts" with condensation...check corrosion and look for component damage on the oft chance the circuit board was damaged by some inappropriate poking or mechanical failure. Reassemble and replace sensor...

For a short life span...or out of warranty and only at your risk (IF have significant other or kids or pets or human DNA... don't do this...) .. guide wire through screen notch and attach to outer screen. Build fortress around exposed sensor and talk to insurance agent for a special rider...seriously be careful.



Did you? Clean screen and GENTLY clean fins of lint, etc....(vacuum's brush head should do the trick...)

Taking all appropriate safety precautions.

...


Here's the 100,000 (yen) tip....with humidifier unplugged, hold down the power button (green button in lower center) and plug in the appliance.

Watch the LCD screen as it conducts a self test...and wha...lah!.

Should have a working humidifier!

Honeywell PN9565 thermostat at hotel. It is a new vtac a/c unit. The room will not dehumidify. How do I reset the thermostat to factory? I already switched out the thermostat and the humidity sensor.

maybe the new unit is too big for the space. If it is cooling, it is dehumidifying. whenever warm air passes over a cold surface water falls out.
IF, however, it cools too fast, it does not take much water out before it is at temp and shuts down.

I owned a Keystone in the past. loved it. just purchased 2 more. NOW - for some reason - they don't shut off when bucket is full. will actually OVER fill and leak. how fix ?

Dehumidifier typically use a float in the collection bucket to detect water level and automatically shut it off once it's full. Have you checked to see if the float is broken or missing? Also sometimes it can get stuck ir jammed up when inserting the bucket, make sure its in place and falling freely down into the bucket.

I have a 50 series w/ digital humidity level readout. Recently unit reads the room at 30% humidity so it shuts off unless preferred setting is set to continuous. Can the sensors go bad that measure the...

If the humidity level is at or lower than 30%, the unit won't turn ON, until the reaches 35 - 40%. It's rare for the sensors to go bad. Just keep in mind, the dehumidifier is reading the humidity near the floor, not up at say, chest level. Humidity levels change every season, so this really would not be that unusual. Make sure that your clean the air intake filter regularly. Cleaning and wiping down the coolant coils would be a good idea, too..

Hope this helped you. Please let me know.

Doesn't run, turn on or anything............I think it has died. Bought in 2004. Any suggestions? 65 pint/2 speed. Hose connection to drain, no reservoir needed.

the full bucket switch on these models goes bad, o.k.,i know,you said its hooked to a hose to the drain so the bucket never fills up,but,seriously,test the "bucket full" (in the upper right hand area of where the bucket installs) shut-off switch,as this will kill one of these units if it goes bad as it carries all the units power through it at all times,i replace many of these every season,if this switch goes bad it shuts off the entire unit

Dehumidifier automatic on and off function not working

Unless you live in a dry environment or place the unit in a hermetically sealed room, it probably will not turn off. As the air dries within the room, more moisture comes in with the air. As long as the air outside of the room is more humid than the room this will be true.

Goldstar dehumidifier won't stay on

Check the relative humidity in the room or space where you are operating the dehumidifier. Damp feeling and actual humidity level are two separated items. Humidifiers will run for a few minutes until it is signaled that the humidity is already low enough and then shut down.

It works when it wants to

Just found this forum noticed your post, it is old I know, hopefully you got your unit working already.

The unit is designed to be operated at temperatures above 65°F(18°C) in normal conditions. If the dehumidifier
is operated in low temperature conditions frost can form in the evaporator coil and the unit will cycle ON/OFF
repeatedly. In this case, please check your room temperature conditions and stop the unit.

My dehumidifier is dead

WIZ huh? NAGEV says:

check the plug!??? - DUH! I also love ...

5) Remove and test the overflow cutoff switch.

6) Remove the humidistat and check it. Replace it if necessary.

7) If the unit still doesn't work, call an appliance repair person!!!

I guess he's only helping the repair person! Who would pay for this kind of advise? The layperson needs details not big words!
