If the desired outlet gas pressure or gas flow rate cannot be achieved by adjusting the gas control, check the gas control inlet pressure using a manometer at the inlet pressure tap. The gas control is likely to have operated for more than 200,000 cycles. 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. 1/4-inch male quick-connect terminals for electrical connections. Because gas is involved, problems with gas valves are a major safety concern. You must log in or register to reply here. Tighten only 1/4 turn beyond finger tight to give good electrical continuity.
