    thanks for trying - should have been more specific in my question as I have a whole house humidifier mounted on the furnace - it was just a curiosity question as to what makes a humidistat go bad - maybe there is something I am doing wrong or could do better to keep it working - humidistat was only about 5 years old and quit working - a thermostat seems to last much longer

I have an AprilAire 550A with bad humidistat. Can't find replacement. Got a 550 but wiring not right. Not sure what to do!


I believe they just updated model number descriptions. The basic design of that humidifier hasn't changed much over the years. I would go to their website and look for the one that is simiar to your model and get the humidistat for it. They are pretty basic devices as far as what the humidistats do. 24v power and common

Hello, sounds likemyou have either a bad humidistat or solenoid valve, disconnect the wires from the humidistat if this turns off the humidifier than replace the humidistat. If not the solenid valve will need to be replaced,

Humidifier will not turn on (no fan, no water flow)

A breakdown diagram of parts etc above.

Shows you the HE360A.
To me it sounds like it is wired incorrectly, the solenoid should NOT get too hot at all. The PDF above shows wiring data.

Humidistat does not turn unit on


check for supply voltage to the humidistat and the humidifier. Also check all electrical connections carefully. It may simply be a bad humidistat. these are non repairable components

I have a model #560..turning the humidistat forward until it "clicks" would cause the water to begin flowing..now, after the "click" is heard, the water does not flow into the reservoir. Do you think it's...


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.

My Aprilaire 700 does not seem to be working. The


you can bypass the humidistat by shorting the 2 brown wires on the bottom of the humidifier. just remove the 2 wire nuts and touch the 2 together (just 24v)if it comes on then there is a control problem with the humidistat or wiring if it doesnt come on the control board or transformer may be bad or you dont have 120v to the humidifier on the plug. also make sure your furnace blower is running cause the hum cant come on if its wired properly unless the fan is running. you also may want to go to www.aprilaire.com and get a maintenace kit from their online store. it comes with pad and new hose along with a couple other things.

I have a Honeywell House humidifier HE 225A-1006.


In order of probability:
1) (incorrect wiring) Make sure that humidistat is in SERIES wired with the furnace.
2) (shorted wires) Check that two wires to humidistat are not touching...use your glasses if you need them!
3) (bad humidistat) disconnect the humidistat and put an ohmmeter accoss the two terminals when it is turned on you should read 0 ohms, and when off it should read infinate ohms, if not pass both these tests, you need new humidistat.
That is it, there are no other possibilites!
