Furnace Humidifier leaking

I cleaned the A-coil in my furnace a few months back and since then the humidifier has been leaking, it seems with the improved airflow it blows or sucks the water inward into the return duct and leaking on the floor.

I don't think it ever had this issue in the past.

I did replace the wick filter last year or the year before and it looks fine.

I tried the different settings on it to reduce the airflow but it leaks in each setting.

It is a Humidaire FH 182H

Any help is appreciated.

Make shure you put the water tube seated correctly in the pad frame.

I think it just floats over the upper tray that drips over the filter.

But I will check it.

Not 100% on that model but many humidifier pads can be installed upside down, a lot of them are directional and are designed so that the water keep getting directed to the inside of the pad, put it in upside down and the water goes to the outside and will leak.

Aprilaire pads are this way, they have a paint dot on them that goes up, if they get put in upside down they leak, we get calls every year from people that make that mistake.

Drain tube is clear.

And the pad is installed correct side up. I tried flipping it around with the same end up and no change.

Its only leaking from the increased airflow as the A-coil was covered in a layer of filth.

I have it turned down low enough that the valve does not allow water to flow into it.

Bumping this after running across the same thing a week ago.
The humidaire pad isn't readily available so many people have used a general pad, this worked fine until the design of the general pad was changed slightly and now using a general pad will cause it to leak, at least in some cases.

So using the original manufacturer parts should fix it?

Probably, what's the pad that's in it now look like? I've only run across this once so far but it had been fine for years then they put in the new style general pad and it started to leak.

Not sure what you are asking as far as what it looks like but it doesn't look like its clogged up.

I should just order a new one from the company that made the humidifier and try it I guess.

Does it have a metal frame across the top? If so you might be able to simply cut it out, the water hits the frame instead of the pad and leaks. google image a general pad and a humidaire pad and I think you will see what I mean. The older general pads had a different design and worked OK in those humidifiers.

Flow through style? Make sure pad and everything is mountted properly and that the drain tube is clear and draining freely. There should be a damper to close for summer time, so if you think it's an air flow issue, close that damper down some.

Yes flow through. All looks good, and tried the damper.

Its gotta be the pad, that is what I am going to try.

It was fine until I cleaned the A-coil, with the improved airflow it started sucking it into the return duct.

I just took the metal frame off and put it back in, so far no leak.

Fingers crossed.

I am not going to miss the mini lightning I have been dealing with all winter.

The worst is when you get a static shock that arcs through a crappy light switch and shocks the hell outta you.
