Water runs out back humidifier into plenum & onto floor
Happens since new but not at reguler times! Have replaced solenoid & the filter. Hear solenoid click on & off. When furnace stops no water flowing out the hose but when on flows great so not pluged. Could it be the thermostat??
Re: Water runs out back humidifier into plenum & onto...
Hi John Your whole question did not show up (maybe you can re-post) . I can answer what part i understand though. If the humidifier was wired in right it will not send power to the humidifier until the furnace is on, and calling for heat. This stops the unit from working in the cooling mode in summer.Make sure your furnace filter is clean as well

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.
I have same problem with no water flow on identical humidifier but was able to fix it. Removed the inlet to the solenoid valve and found (1) a small taper mesh filter inside (2) a small diameter orifice that was clogged. Cleaned the miniature filter and used a sewing needle to open the orifice and now works perfectly.
Neither, even if the solenoid or humidistat stick, it should always drain properly. Is the unit mounted on the cold air return duct or the supply plenum? If it's mounted on the supply plenum, the water panel might be getting blown forward and spilling the water. High efficient furnaces also can leak water on the floor if its drain is restricted. If hum. is mounted on return duct make sure drain is clear by blowing through it. On Honeywell hum's I've seen the rubber hose from the solenoid valve to the distributor tray leak too, check the rubber 1/4" hose.
The humidifier is designed to "pull" the air through the water panel. After it does the humidified air will re-enter the plenum on the side of the opening that it is pulling in from. Just keep the water panel replaced every year and you will be fine.
No. when you remove the front cover it will automatically disconnect the power supply. Try changing the water panel and cleaning out the orifice and filter screens located in the water lines connected to the solenoid valve.
Easy fix: Check the solenoid. Turn off the power to your humidifier and the central air unit. On the side of your humidifier is a brass solenoid. It can get clogged with lime and calcium. Most videos and instruction manuals tell you to replace the solenoid. No need if you can turn a wrench. 1. After all power is off turn the water off to the humidifier and disconnect the top line water line at the nut. 2. Disconnect the bottom line water line that will go to your humidifier. 3. Take a Philips screw driver and remove the two screws that hold the solenoid on the side of the plastic housing of the humidifier. 4. Leave the wires connected unless you need more room to work. If you disconnect the wires then label them with tape (colored) so you put them back on correctly. 5. In the inlet or outlet water pip of the solenoid is a trainer that may be clogged. With a paper clip pull it out and clean it. If it’s clearly clogged then stop and put all back together. That may have been your problem. 6. If it’s not clogged then it may be clogged inside the solenoid. 7. The nut on the end of the solenoid is silver. Take it off and the magnet (main power unit) will slide off. 8. Notice the flat head screw post on the end of the solenoid. Turn it and remove. Be careful as a small spring loaded plunger is inside. 9. Take apart and clean all parts. You should be able to blow air in the intake water line tube and it go out the out water line tube as well as were the plunger hits in the center of the solenoid. If not then it’s clogged. 10. If clogged then just soak all but any parts with rubber or plastic in a small white vinegar solution for a couple of hours to eat away that lime. If it’s not clogged then you probably have a bad solenoid. 11. To check and see if the solenoid is bad just put it all back together but do not re-wire the solenoid to the humidifier. 12. Turn on everything without the wires going to the solenoid (turn on meaning put power back to the unit. 13. When the system is running as it should without the humidifier and solenoid wires attached check the two lead wires with a volt meter for 24v. If you have 24v then you have a bad solenoid and need a new one. If no 24v then you may need a new control panel. Hope this helps you out.
