General Filters 1042-LH Humidifier - Answered Questions & Fixed issues

Hello, sounds like the solenoid valve is sticking and will need to be replaced.

General 1042-L not putting moisture in the air. Water valve is open and getting to the filter. The unit is clean.

Hello, water not reaching the humidifier can be caused sediment buildup in the strainer of the solenoid valve, a faulty solenoid valve, sediment at the saddle valve, or no power to the solenoid valve. The fan will run continously if the relay that engages the fan is stuck as it is gettimg a constant 120 volts.

Hello, first thing is check is the strainer going into the solenoid valve for sediment, if there is clean the strainer and reinstall. If the strainer in clean the check if you are getting 24 volts to the solenoid valve, if you have voltage and the solenoid does not let the water thru replace the solenod valve.

Hello, it depends where the sound is coming from,if it's in the supply water line it could be caused by water hamer or the inlet side of the solenoid valve might be clogged up with sediment. Water hammer is when the solenoid closes under high water pressure and a water hammer arresters should be installed. If the sound is coming directly from the solenoid valve and is more of a chattering sound then there is a loose low voltage wire or the solenoid is going bad. If you disconnect the power to the solenoid and the chattering stops then solenoid must be replaced as it is the cause of the noise.

Hello, if you are getting 24 volts to the solenoid and it does not open then the solenoid is bad and must be replaced.

Replacing this solinoid valve is not hard to do. This is something the homeowner can accomplished with small hand tools. Turn power off at the furnace and the inlet water off at the saddle valve.Remove the water line at the valve and the connector exiting the valve. Remove the two screws and the valve is off the unit. Armed with the make and model number of the unit goggle the manufacture with the model number and order your replacement valve on-line. Install the new valve opposite of which the old valve was removed or per manufactures instructions that may come with the new valve you orderd.

Hello, there could be sediment built up at the saddle valve outlet which is preventing water from flowing to the humidifier, If that is clear than the saddle valve must be replaced.

Hi,
To get the humidity to rise more or faster, turn the "fan" switch on the t-stat to "on" and run the fan more...
The humidifier only adds moisture to the air when the air is moving through it and the air will only move through it when the blower is moving the air...
Depending on the heat loss of the house and the capacity of the heater, the fan may have to be run extra to get enough moisture to the house...the run time of the furnace it's self may not be enough...

Play around with it and see what it needs...only you know exactly what humidity you are looking for...you have the equipment to get it there you just need to figure out what the combinations are to get it there...

Make sure damper dial on humidifier if open, winter. Also most humidifiers recommend to supply unit with hot water instead of cold (evaporates faster).

Try to tighten the compression nut on the saddle valve and see if it will stop, if it does not stop then you will need to replace the saddle valve.

I would first check to make sure you have water to incoming side of the solenoid valve. Most inlet and outlet fitting are compression type so you can carefully loosen nut on incoming side to see if you have water there.You don't want to take the nut off just back it off a liitle to see if you have pressure there.If so then retighten nut on incoming side and loosen nut on leaving side. Turn up thermostat to actuate solenoid valve.You should be able to hear a slight click when the valve opens.
If you have water on incoming side and you can tell that valve is working but you are not getting water flow then shut off water supply to humidifier and remove inlet nut and and slip pipe back to see if there is a blockage there. Clean as needed or replace solenoid if it's not working.If you have flow into unit but not out then check outlet side for blockage. I hope this helps . Thank you.

Sorry to read about your problem, I hope this helps you out.
if you changed it, and it still runs, you have a control switch problem, its telling the relay to stay on.....

yes, the water will flow to quickly without it. you can use a very small dill bit to clear it. if it flows to fast you can control it using the shut off valve. hope this helps.

Hi.

Check the solenoid valve, that is probably stuck open. Before doing anything else ensure that you have disconnected power from the humidifier, so to reset the electronics.

There is a 120 volt version AND a 24 volt version of the valve , ensure you purhase the right part.

Here diagram.

Here the parts.

Home depot sells a pad that will work.

Depending on were youre humdistat is mounted either on tha return duct near the furnace or on the wall in the living area this should be an easy fix turn the dial down there is is to much humidy.

Hi, if the unit is leaking and it looks as though it is coming from the PVC pipe, more then likely its leaking at the unit its self where the pipe connects. Water will run down the pipe and drip down line. Dry it off and put your hand around where the PVC pipe screws into unit. Unless the pipe is cracked, this is where the leak is. If the fitting is a male or female threaded PVC fitting and a piece of PVC pipe that goes to the drain, you can repair this very easy. Just cut the pipe near the fitting with a hacksaw. Unscrew the fitting that goes to unit. Go to a hardware store like Home Depot, take the old fitting with you and buy a replacement. Buy a coupling, a small can of clear PVC glue and a small can or tube of pipe dope to put on the fitting threads. Screw the fitting in first and make sure it has pipe dope on it, get it tight with pliers. Take the pipe and coupling and glue it on the pipe. Put glue on the other end and slide it in the fitting that was where it was leaking before. Hold it in place for a few seconds. Once you put the glue on, be ready to put it together as it drys super fast and you cant take it apart once it sets. Very easy to repair and the parts cost pennys. Keep me posted. You can do this and will learn about plumbing! Good Luck.

It's more likely to be the valve. Turn the humidistat (rheostat) up and down and listen for a click at the humidifier valve. If it clicks and no water goes through, it's the valve or something in the water supply. The best way to test is to use a meter and check for power at the valve. They sometimes fail even if they appear to be operating. Scale (lime buildup) is usually the cause.
