The Valve could probably be removed and cleaned but whatever is causing the valve to leak may have damaged the valve sealing washer / o-ring or the valve seat. You coud try cleaning it and replacing any seals, but I suspect that only replacement of the whole assembly will fix the problem properly.

Humidifier doesn't work

Hello, if there is water to the solenoid valve but not passing through it than the solenoid valve is malfunctioning and must be replaced. However, if there is no water at the solenoid valve then either the saddle valve or supply line is clogged with sediment. A easy way to chek the solenoid valve is apply power directy to the solenoid valve from the transformer, if it does not open then replace it.

No water flow into the filter

Hello. the first thing you need to determine is if the solenoid is getting 24 volts when the furnace turns on, you should be getting 24 volts at the solenoid valve. If not you need to start at the transformer and see if you are getting 24 volts there, if not then most likely the transformer is bad and must be replaced, if you are getting 24 volts at the transformer then check the wiring and make sure it;s tight. also check the humidistat and sail switch/ current sensing relay to make sure they are working properly. If you are getting 24 volts at the solenoid valve and is not allowing water thru than it must be replaced.

Water is continually feeding humidifier even when furnace is not running

I would recommend that you shut off water supply and remove solenoid valve.Disassemble valve and clean it making sure that there is nothing stopping the valve from fully closing. If you can not find any problem after cleaning then reassemble and leave the outlet connection loose.Turn on furnace and see if the valve is even trying to close. If not then you need to replace the solenoid valve. Hope this helps. Thank you.

Not sure if this is the right model, it is attached to my furnace, at any rate, the tech said that the solinoid valve needs to be replaced and the malfunction was caused by "hard water" which...

I had to replace the solenoid valve on my unit and it cost $125.00. This was just for the part, no installation. I then took the solenoid apart, soaked all the parts in white vinager (disolves calcium) reassembled, and it worked like new. However there are some small rubber seals inside the solenoid, that will allow it to leak. If they fail, your only option is to replace it. Hope this helps.

I don't really have a "solution" but you might want to check the resivoirs for lime/calcium buildup as they can defeat the signal by the sensors thinking that the system is full of water. Some vinegar and a toothbrush resolves this. The other possibility is that your sensors may be deflected below (not in contact with) the resivor bottom.

Water and motor always run on Aprilaire 760, even when furnace is off.

Hope this solves your problem, look for the humidistat, it should be located on cold air return duct near furnace, make sure it is not set in the on position, if it is, then this is why it is staying on, please set humidistat any where from 20 to 35%, never over 40%. If the humidistat is set properly and is still running, you may have a electrical problem, humidifier circuit should only receive power(24 volts) when the indoor blower motor of furnace receives power, also if you have galvanized plumbing in your home, you may have a piece of rust or lime deposit in the humidifier solenoid valve preventing it from closing, turn water off to humidifier and disconnect water supply line entering solenoid valve inspect & clean protector screen. Good luck.

Aprilaire 600 problem

It sounds like you got it...

The solenoid will not open with only 13 volts to it. Jump or apply the full 24-27 volts to the solenoid and see if it clicks and opens and allows water to flow.

If the valve still won't open or pass water, start looking for a plugged inlet solenoid inlet screen or a faulty solenoid valve as well as a faulty humidistat.

Solenoid valve will not shut when the furnace is off

Most likely you have crud buildup in the solenoid valve. But first make sure that you test accross the solenoid connections for voltage when the furnace is OFF. Put your meter to AC volts and see if you see 24 Volts when furnace is ON and 0 Volts when furnace is OFF. If you get those readings then you need to replace your solenoid valve.
Available from mfg for about $55-60
or on ebay for about $40 shipped.
search for Aprilaire 4040 Solenoid

If the above tests fail, you will need to ensure that the wiring is correct and not shorted, but is probably your valve. Install a fridge water filter in the water line to help prevent this in the future.

Appril air 600 wont work

the change water panel light is just a timer. it does not sense that the water panel actually needs to be replaced. sounds like you have a solenoid issue. if you have water to the solenoid and are certain you are getting 24v to it, the solenoid is ethier bad or plugged with calcium. most likely calcium. sometimes you can take them apart and clean them. so, it you can hear clicking at the solenoid when you turn the humidstat up and down. try cleaning it.
