Aprilaire 600 not getting a Solenoid click and no water flow at all
When I put it into test mode recently i thought I heard something snap. Ever since that snap I cannot get the solenoid to click and there seems to be no water supply at all. Any suggestions? I thought maybe I needed to take the cover off the humidstat and see if something needed to be reconnected. Not sure though.

Your solenoid may have seized. The best way to check is remove the cover off the humidifier pad housing, remove the rubber tube of the distribution tray and see if water comes out while in the test mode. If you have a volt meter you can test to see if you have 24volts at the two wires connected to the solenoid. If you have 24volts there but no water ,the solenoid is bad if not you may have a bad humidistat or humidifier transformer depending on how it is wired.

The solenoid valve unit will work upside down however, I am concerned that the tech that installed the unit might have installed it backwards. Look on the side of the valve the solenoid is connected to and you should find an arrow. Thats the direction of the water flow.A strainer helps keep the valve clean however if there is dirt in the valve it would be stuck opened not closed. Make sure the solenoid is getting power via float valve. If the solenoid is getting power you can tell by touching the top of the solenoid with a metal non magnetic screw driver. It will pull the screw driver like a magnet. Good luck
Water will flow over the filter pad as long as the unit is calling for humidity. once the unit is satisfied the solenoid valve should stop the water flow. if the water continues to flow with out call then solenoid valve has failed open. hope this helps.suppling an owners manual in case you need one.
turn the saddle valve in and back out. sometimes the small pin hole for the water gets plugged with something over the summer when the units aren't running and just turning the valve in and back out clears it out and allows the water to flow. check to see that you have water flow at the solenoid and if you do then it is probably the solenoid that is bad.
if it works in the test mode then it should be okay but you can get a humidity gauge from radio shack and set in the house to see how high or low its is. the humidifier is only going to give a max of 45% humidity
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.
When your unit is on normal the outside unit works and the inside only the fan runs. your heat pump does not remove any humidity when it operates so the installation cotractor did not wire it to operate then. you can change the wiring on the humidifier to operate all the time by wiring it to the fan (g) terminal then it should work just turn it all the way to the lowest humidity when you are in cooling mode.
solenoid valves dont just burn up just like that you have a recurring restriction due to bad water.Check the saddle valve at the water heater first then check for postive water flow at inlet to the solenoid valve,if you have water flow the valve is clogged with sediment.
