Do plumbers work on gas valves?
Yes! When most people think of plumbing work, they think of water lines and plumbing fixtures like toilets, faucets, etc. But there are specialty plumbers who can also install and repair gas lines. These plumbers work on gas water heaters and other gas-powered appliances around the house—both inside and outside.
Where is the gas valve on the furnace?
The gas valve is inside the furnace cabinet. Furnace gas valves are wired to an electronic component known as a solenoid, which receives signals from the thermostat control. This causes the gas valve to widen or narrow in front of the pilot light to respond to changes in building temperature.
How does a gas valve work in a furnace?
The furnace gas valve operates by electromagnets. The primary valve — also known as the safety valve — supplies gas to the pilot light. The second valve — also known as the main valve — allows gas to flow to the burner trays. The thermocouple (or thermopile) generates the power holds the safety valve open.
How do I know if my gas valve is bad on my furnace?
If 24 volts is coming from the board to the gas valve terminals and you don’t hear that little clicking noise the internal valve makes, you could have a bad gas valve. To double-check, take the leads off to the gas valve and check there.

What happens if furnace gas pressure is too low?
If the gas pressure is too low, your furnace’s efficiency will go down. Not only that, but it will lead to a greater amount of condensation of burned gases. That’s because it greatly increases the risk of furnace overheating. When this happens, all manner of internal components may become damaged by the excessive heat.
How do I know if my gas valve is open?
Gas shutoff valves When the long side of the nub or handle is parallel to the incoming gas line, it’s open and the gas is flowing. When it’s turned a quarter turn, perpendicular to the incoming pipe, it’s closed.
Does it matter which way you install a gas valve?
VALVE ORIENTATION: Ball valves may be installed in vertical or horizontal pipe runs, they are bi-directional therefore flow direction is not critical, however the best practice is to set up the valve handle to point in the direction of flow whenever possible.
