Mine timer will go on but it won't turn off why is this happening?

My timer has worked fine for at least one year. No problems with turning off.

This timer stopped working for me after 6 months, I would get a digital timer, they last longer.

We had this timer. It worked for 9 months, then one day it stayed on. If you read through some of the reviews, you will find, as I did, descriptions of small plastic pieces inside the unit that eventually break off. When this happens, the timer doesn't respond appropriately. We switched to the digital model. It's more complicated to set up, but at least it is still working.

This happened to me also. I noticed that the little tabs that determine when the timer goes on were bumped and not fully in or out. I set them correctly, either in or all the way out, and it's been working correctly since. I hope this helps you.

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.

You are lucky that it goes on. We could never get ours to work at all, so we trashed it and got a different one.

You are correct. I have had mine and it did the same thing. Pushing the reset and timer button and the light went out. I cant find my manual. Thank You!

There are time, light/dark and test variable potentiometers within the unit.Find the one for time and increase it a little bit-- one quarter of a turn to the right to Increase the " on time" . It may be setting at it's lowest " on time " setting now.This would explain why it comes on and goes off . Try this to see if it works.Bill cypress tx. "

It goes off for about a minute, then shuts off. Best timer I've ever had and I've had lots of them.

I've never set the timer, and it will run until it is out of water and automatically shut off.

I am guessing you have a defective one. Mine works perfect; on/off and nothing more.

Yup that's what I have mine on. I bought a cheap timer (2 pack Stanley) from Amazon and it works perfectly. I use the timer function all the time and then turn timer off when I want to operate it manually

I have the same issue. It will not turn off even when the button is pushed.

I set mine on "timer" and then switched it to "on". It worked for a while but about half of my timers wouldn't hold the actual time so they wouldn't come on at the right time.

You can turn it off by pushing the button until it says off, and again until it says auto so it still functions on the timer. Same for on.

since it is intermittent it sounds like you may have a load (that is not always on) connected on the timer line side. The timer side needs a dedicated path. Also, you may want to check and make sure that the voltage on the line side matches the voltage you set the unit to.

I have a button on the top to start and stop it. Just push that button and it should go off.

Oh my word. Thank you for the question. YES. I tried it as you said... I was wondering why my timers would all start over. I'v purchased a lot of them, so I won't forget things.. Yes... I put in 3 seconds, it went off; so I pushed stop. Then, I just pushed start again, and it counted down the 3 seconds. I did it about 4 times... 'cool' and thanks again for the question.

Mine got into exactly the same state. Turns-out the battery was simply under-powered (so not completely dead, but not powerful enough to make the timer work). When I changed the battery, the timer starting working again just fine!

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

You almost certainly have a bad battery. I own several of these timers, and the batteries last for many months even with heavy usage of the various features. I believe the clock mode is running in the background all the time and you cannot turn that off.
