What Is A Furnace Gas Valve How Do They Work Spurk Hvac The furnace gas valve is the heart of your home’s heating system. its primary function is to regulate the flow of natural gas or propane into your furnace, ignite the flames, and meticulously manage temperature to meet the heating requirements of your home. when a furnace gas valve malfunctions, it not only leads to an inefficient heating. Gas supply. ensure the furnace’s gas supply is in the on position. the main supply valve should be within six feet of the furnace. follow the black metal gas pipe outward from the furnace to the valve. the valve typically has a brightly colored lever or knob. the gas supply is on when the lever is parallel to the pipe.
What Is A Furnace Gas Valve How Do They Work Spurk Hvac A furnace gas valve is a component of your furnace’s fuel system. the furnace gas valve opens and closes, which allows the flow of gas to the pilot light and burner (s). while the component itself if actually rather simple, a furnace gas valve is a crucial part of your hvac system. furnace gas valves are only seen on gas fueled forced air. Step 1: the furnace starts by receiving a call for heat from the thermostat. step 2: the control board initiates the sequence of operation and sends a signal to the combustion air intake damper. step 3: the combustion air intake damper opens to allow fresh air to flow into the furnace. 4. inconsistent flame. the flame might be coming on for a few seconds but then shutting off. to check and solve this issue you can see if the voltage is off or the gas pressure is low to the valve by putting a “t” (fitting in line with the hose) to connect to your manometer. Generally, there will need to be a natural gas composition of 4.3–15% for combustion to happen. if the air is composed of less than 4.3% natural gas, the mixture will be too lean, and combustion won’t occur. on the other hand, an air mixture with more than 15% natural gas will be too rich for combustion.

Check the inlet and the outlet side to see if the pressure is dropping on either side of the valve. another reason the flame could drop out after only a few seconds of burning is the flame sensor. if the sensor doesn’t detect the flame, the control board will signal the gas valve to shut down.
