Here are a few things to check:

-make sure the heating element is clean. If there is a thick layer of scale (mineral deposit), then the unit will not turn on.
-there are magnets on the water reservoir that allow the unit to turn on. If these magnets are not lined up properly, then the unit thinks there is no tank, and thus, not turn on.
-turn the humidity up past your target point. The humidity near the unit could be a lot higher than the rest of the room, causing it to shut off prematurely.

Hope this helps!

This is a posting from someone other than myself...however, it presented a good solution.

A solution to the problem with the fill cap failing/leaking. It was/is not the cap, it's the gasket/grommet/o-ring. Remember "THE MAGIC BULLET", well the gasket, that's where you tighten the top to the bottom, some are white and some are black, THEY FIT the Honeywell HWM450!!! ------- Problem solved.

I usually just balance the tray upside down on top of the base and fill the edges with vinegar. You could also put the the tray in a bowl filled with vinegar and submerge the whole thing.

The obvious solution is to replace the humidifier that became defective while in storage.

Very first thing. If it won’t turn on, unplug it, and check the cord....especially if you have, or have had, a rabbit that has already chewed through every other wired devices you have ie: TV, satellite dishes, DVD players, other electrical cords.
I got my humidifier year before last and only used it a few times that year. Our humidity was fine until now, so the humidifier was still new as far as I was concerned. I checked every online help suggestion before I remembered Buster. Sure enough....exposed and partially chew wiring. I thanked God that I hadn’t been shocked.
Thank you, Daddy, for teaching this 70 year old grandma how to splice wiring and install other electrical wiring when I was a teenager. I miss you so much.
CAUTION: UNLESS YOU KNOW EXACTLY HOW TO SPLICE WIRING DON’T THINK YOU CAN FIGURE IT OUT. TAKE YOUR APPLIANCE TO A SPECIALIST TO GET A BRAND NEW WIRE PLACED ON YOUR APPLIANCE. I CANNOT EMPHASIZE THIS ENOUGH. IN FACT, TAKE IT TO AN ELECTRICIAN ANYWAY.

Needs to be wired to work on the blower circuit. You must be drawing power from a source that is always on
