Furnace Gas Valve Operation And Testing 2 Stage And 3 Stage Youtube In this hvac training video, i show how 2 stage and 3 stage gas furnace valves work, how they are electrically powered, as well as the pressures that they ru. This one shows how to initiate the 2d stage of a 2 stage gas furnace without waiting for the delay.
Two Stage Gas Furnace Youtube If you're trying to figure out how to diagnose a bad furnace gas valve, this is a video that explains what the gas valve does, why it's important, how to fig. Select the resistance ohms mode (usually shown as Ω). hook up your multimeter’s probes to the terminals on the gas valve. if the reading is ol, then the gas valve is bad. another way to test a gas valve is to hit it with a hammer. no, really by hitting your gas valve with a hammer, it can become unstuck and open up. 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. 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.

Gas valve troubleshooting looks for a problem. if something is wrong with the internal components of the gas valve, the gas valve should be replaced. the gas valve cannot be repaired in the field. only the gas valve manufacturer or someone certified by the manufacturer of the gas valve can make repairs. then re certifying the safety of the gas. Gas valve operation. both single stage and the two stage furnace have a single valve; the single stage valve can either stay open or be shut; there is no in between. meanwhile, the two stage one can operate at two different modes. it can be either 70% open or fully open. air blower. most single stage furnaces have a fixed speed blower.
