Question about Heating & Cooling
If its opening and closing it sounds to me like a loose wire nut on your 24volts to your water solenoid valve. The only time that the humidifier should come on is in heating mode and then when the furnace gets up to temp and the blower starts. If furnace is older it will have a current sensing relay located in the blower compartment with a plastic box and two wires coming off of it.One of the blower wires( generally RED for low speed) should be going through that sensing relay.If you have some slack in that blower wire try wrapping it around that sensing relay a few times. I would chek all my wire nuts first though before you do the sensing relay. David
