Is your GeneralAire humidifier not getting water? The solenoid valve is often the culprit. This General Aire 7052 (also known as part #1099-42) is a complete solenoid valve assembly replacement kit for several popular GeneralAire humidifier models: the 1099, 1099L, 1099LH, and 1099R. The great thing is it comes fully assembled with the valve body, the solenoid coil (that's the electronic part that opens and closes it), and the orifice kit, so you get everything you need in one box. It's a 24-volt valve, which is standard for these whole-house humidifiers. Replacing a faulty solenoid valve can fix issues where the humidifier isn't producing any moisture or is leaking water. It's a common maintenance part. Before you order, double-check that your humidifier is one of the models listed. Installation is usually a matter of disconnecting the old valve (remember to turn off the water and power first!) and connecting this new one in its place. Keep your humidifier running smoothly and your home comfortable with this genuine replacement part.
