The timer is working for turning by humidifier off, but cannot get it work to turn the unit on. Any suggestions?

Some humidifiers will not turn back on when power is turn back on. You can test this. With the humidifier running, unplug it from the wall. When you plug it back in, does it start right away? If it does not, you will want a different humidifier. I actually had the same plan and had to get a different humidifier.

Read the instructions CAREFULLY. If you have the current time set properly, you can start at "To Program the Timer". I believe if you take the time to work through that carefully one step at a time. you'll be in business. This timer has a LOT of capabilities for settings, and it is easy to miss a critical step if you're only trying for one on/off cycle per day, at the same time every day. That was, however, all I wanted to do, and by wading through carefully everything is working fine for me.

I have not been able to and my belief is that its humidifier gauge doesn't function properly and never will.

Your timer may not be shutting off all power to the device. I would use a test light and check for current.

Make sure the little switch is positioned in the center Position. Left is OFF. Center is Timer program, and right position is on continuous. If the clock rotates automatically then it is wired correctly. If it still does not turn off then I don't know what the problem could be other than a mechanical failure.

The unit is a simple switch. You set the humidity at the desired level, and the switch CLOSES when it reaches that level. Your outside H<50% won't turn on the fan, it will turn off the fan. But you could have the outside H<50% control a relay to do this I think.

There is a button on the side - the red one in the photo. If it is flipped in the off position, it will lose time. If you flip it to "timer" (I don't have mine in front of me so I am not certain of the exact indicator) it will time perfectly, and will actually turn on and off. I had a similar problem with mine and discovered that the switch had probably been knocked into the other position. If it's not that, it probably needs to be replaced.

My husband said that shortly after installing ours did that and we just turned off for ten minutes, then it worked okay. He did re-check the timer setting and that was okay. So might need to check and make sure its on a time to go off. If it set for a long time till it goes off then that might be the cause.

There is a blue-green light at the on/off switch. It is dim but, for those who can accept no night time disturbances it may bother you. It can be defeated by turning the humidifier on /off switch away from you. At a right angle from you it should cause no trouble. You can not run the humidifier without the light being on.

Make sure you have a 120 volt supply line not 240 volt. If you have the correct voltage then make sure the timer disc is properly seated which I suspect you have done, then it is probably a faulty timer.

Ron,Have you checked your on pins to see if they have the small foot that hits the switch,it seems that if the timer is turning to turn it off unless there is something wrong with the on off pins it should function .Do you have 4 pins two red and two black?John O'

evidendenly your humidity is lower or the same as number being seen so just press button under number you'll see it go down to lower number and you'll see the go light go on and hear it start up, i set mine on 40, bu it does shut off when it reaches 40 and if you unplug unit you have to do button all over again

Hi Bo, I have used one of these WH21 for the last 25 years. This version of timer is only for controlling on and off in a 24 hour period. It will not help you with the issue that you described. Thanks,Ed

Interesting. I would contact the vendor. My night light turns on briefly when you push the button lightly and turns off when you let go. It also turns on permanently when you push it more firmly. I never use these night lights though, so can't help you there. I do highly recommend this humidifier, though. I think if you return yours and get a functional one you will be happy. All the best.

Turn that valve manually on for 5 minutes. You are going to turn on were it say manual it have for 5,15,30 etc minutes that way it will get fix. I have that problem at that time that I put the timer.

Hit reset button. Turn off unit for about 30 minutes and when you turn it back on make sure it is on the low (I) setting and that its not set beyond the medium mark on the temperature gauge. It should work. I have had several units and threw one away only to later discover that doing the above steps work.

While the internal humidifier will work, I recommend purchasing an electric/battery operated model. They are much less work, and I add water about once every 3 weeks. I set the humidity level I want, and it does the rest, removing the guess work.

Turn the knob untill the timer resets for the panel. Then readjust to desired humidity
