Dealing with a water heater that won't light, won't stay lit, or is leaking gas? This Honeywell WV8840A1000 gas control valve might be your fix. This is the brain and safety device for your gas water heater, controlling the flow of gas to the burner and managing the pilot light.

Important note: This is an open-box item. The seller states it was \removed from a brand new machine,\ so it should be in excellent, like-new working condition but won't come in a sealed retail box. It's the iconic green Honeywell valve. This model (WV8840A1000) is also compatible with WV8840A1050, WV8840B1109, and WV8840C1404 units.

Replacing a gas valve is a common repair for aging water heaters. ***WARNING: Working with gas lines can be dangerous. This repair is recommended for licensed professionals only.*** If you're a qualified technician, this open-box valve offers significant savings. It's electric-powered (uses 24V from the thermostat) and controls the main gas valve and pilot safety. Get that hot water flowing reliably again.
