Should water be continualing running through the drain tube?

Hello, usually this is a sign of a drain problem or the water is entering the humidifier too fast. If the water is not draining at the end of the drain line something is preventing the water from flowing. I would also make sure that there is no heavy mineral buildup on the water panel pad this can cause water to leak out of the humidifier. Lastly check to make sure there is a orifice inside the supply water tubing leaving the solenoid, if not this causes the water to enter the humidifier too fast.

Hello, usually when a humidifier continues to run with the furnace off it means that the solenoid valve is stuck open and must be replaced.

hi the water runs down the pad the fan blows air across is , this controled by the stat which should control the water flow / on or off, this should be under warranty in the first year

If the water stops when the heater is not running then the humidifier is working fine. I know it seems like alot of water but that's how it's designed.

If the water continues runs nonstop even when the heater is turned off, you might have either a bad solenoid valve or a bad humidistat. Simply disconnect one of the two low voltage wires going into the unit. If the water turns off then your problem is most likely your humidistat or the low voltage wiring. If the water continues to run even when the low voltage is disconnected you have a defective solenoid valve.
Good luck.......

A small discharge of water coming out of the bottom of an April Aire drain spud is normal. This feature constantly tries to rinse the system. This helps to prevent the possibility of mold or bacteria accumulating in the unit from standing water. It may appear to be alot of water. But be reassured that you are breathing in cleaner air. Now if it continues to drain constantly even when it is turned off then you should repair the unit.

check to see if you have 24 volts between to 2 yellow wires coming out of the water solenoid. if you have 24v, then it is still getting energized to run. if it does not have 24v and the water is still running, the solenoid is stuck open. most likely from water deposits. sometimes you can take the solenoid apart and clean it, but probably better off just getting a new solenoid.

Check your plastic water orifice. It is in the hose fitting connected to the outlet tube of the water solenoid. It should be a blue one. Mine was completely eaten through, allowing full water flow, and thus overflowing the distribution tray. I replaced mine yesterday and no more water drips. May as well reflace the filter on the inlet tube of the solenoid at the same time. I used a piece of very stiff, but thin, wire formed into a small hook to remove both old parts. Replacements are readily available from multiple sources on line.

Clean it and dry it thoughly. Apply a small amount of 100 % silcone caulking with you finger. Seal it on both sides. Allow it to dry thoughly before it gets wet or it will leak.

The filter panel may be replaced from the top or bottom but it's less hassle to replace from the bottom because the top tray retains a small amount of water and also because you must be mindful of working around the feed tube assembly. Also, when replacing the filter panel, clean both trays (requires removing both trays, water feed tube and drain tube) and drain tube ... use a 8 water -1 bleach diluted solution or other anti-bacterial solution and wipe the trays and pour some into the removed drain tube (not the feed tube!) and shake it up a bit. Be careful though as you do not want bleach solution getting in your eyes, nor on your skin and clothes!
