I have a York Affinity furnace with a Honeywell humidifier. It is three years old and this season I have noticed that there is watwer leaking down from the top and leaking in the midle and pooling at the bottom. I had reduced the air flow on the by pass and reduced the water flow by adjusting the valve. It ran fine until the weather got cold and it is now leaking again. I have shut the water valve and the humidity controls at the wall humidistats and on the vents. It is still leaking. I am afraid that I am damaging the heat exchangers. There are no York dealers within 40 miles. Any suggestions?
Thanks.

Clear the drain line on the humidfier. You probably need a new pad also. They are supposed to be replaced every year.

The pad is brand new and the lines are all working. I turned off the humidifier and closed the valve for the water supply. The leaking has stopped ands there is no more water pooling at the bottom. I will open the valve la bit and keep the by pass damper on the summer setting. I think too much air is passing over the pad and pushing water into the box rather than working as a humidifier. I have two furnaces and they are similarly equipped except the leaking one is a bigger unit. Thanks for your suggestion. I will report back later this week on whether the unit is leaking again. I am hoping that the reduced water flow and less pressure makes the leaking stop and results in some humidity in the air.

After a week of no leaks with the entire humifier system turned off. I heard a binding noise from the blower fan when thye second stage would come on. Previously I would back off the screws a turn or so and the noise would disappear. This time the noise did go away but the leak returned. What is causing the leak? There is no water entering the sysytem. Help.

If this is a high efficiency gas furnace it could be a plugged condensate drain or a cracked secondary heat exchanger.

((Previously I would back off the screws a turn ))

What screws are you backing off?

On a 90% furnace it will create condensation while its running. In the vent pipe and secondary heat exchanger. Check around the vent pipe and inducer motor for water.(common place for a leak) Check the rubber tubes on the collector box and condensate trap.

I am backing off the black motor that has hoses connected to the vent pipe. What would be the symptoms of a cracked heat exchanger. The nopise I mentionesd lasts about 30 seconds and the heat comes on at a higher speed.

Thank you, I will do that.

The black motor is your inducer motor if your backing out screws on it that's your water leak.

It is clear to me now that all the problems are user error. I checked the noise on my second unit and it is the same as the unit that was leaking. It is normal operating sounds. The motor on the second unit is tight at all the screws. By loosening the screws I was breaking the seal and the water was leaking. I have two problems now. First I hope I have not caused any damage and second I now have to explain to my wife what happened. Thank you for your assistance and thanks to everyone that offered help. I wish you all a good holiday and a great new year.

You did not damage the unit at all. Screw it back down tight it should reseal fine. The noise your hearing I'm not sure about. It should not be making a real loud or vibration noise.

Hi cornell01... I am actually interested in an other post where gave an answer about white specks in a dogs eyes. I do not know how else to reach you except via this way. If you are still out there and am willing to contact me be do so [email protected]. My vet too says my dog has something (probably cataracts) on her eyes. My puppy shows no signs of eye site problems and can follow a red lazar dot with ease! The breeder who is very well known, says she has never encountered a problem and for me to get a second option...
