A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all. Install sediment trap in the supply line to the gas control. thatguy, I hear you. DO NOT JUMPER THESE TERMINALS. If it then "clicks" meaning it is opening with voltage supplied to it than most likely it's not the gas valve which is bad. Gas valves nowadays are one piece with 100% shutoff for the pilot flame gas and shutoff valve etc all in one valve. wc [1.8 kPa] inlet pressure and 3.5 in. If the pilot flame is engulfing the thermopile and you are not getting enough voltage to open the main gas valve then the thermopile may need to be replaced.Supervision is needed by a licensed HVAC Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.We've Partnered with TruTechTools.com! Exposure to water, dirt, chemicals, and heat can damage the gas control and shut down the control system. A separate reset button must be held down to permit gas flow while lighting the pilot; can be pushed down only in the PILOT position.

Gas valve troubleshooting looks for a problem. The gas valve cannot be repaired in the field. Never use any tools. Readings outside this range indicate the gas valve is defective and must be replaced. This decreases gas pressure under the second automatic valve diaphragm and repositions the valve disc further from the seat. Unscrew compression fitting from the pilot outlet (Fig. ny outlet pressure change is immediately reflected back to the pressure regulator diaphragm, which repositions to change the flow rate through the regulator valve and, thus, through the diaphragm-operated automatic valve. I go over how it is Wired, wha. 0000044882 00000 n One more troubleshooting tip, on a residential gas furnace if a gas valve is not "clicking" meaning it's apparently not receiving 24 volts you can jump directly off of the control board using the R and the C terminals, R to one terminal on gas valve and C to the other terminal on gas valve (or wherever else you can retain 24 volts from) to the gas valve. Open the manual gas switch if the gas valve fails to operate and look to see if gas is flowing to the main burner or pilot. The condition of the wiring is also suspect; loose connections, old oxidized control contacts, an old thermostat, are all potential problems. A stuck valve could release gas into the air without regulation or the valve could cause the unit not to fire up at all.
