GAS CONTROL KNOB SETTINGSThe gas control knob has three settings:OFF: Prevents pilot and main burner gas flow.PILOT: Permits pilot gas flow only. If resistance is outside of specifications listed, the gas valve must be replaced. 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. Apply a moderate amount of good quality pipe compound to bushing, leaving two end threads bare. If another gas leak is detected, tighten adapter screws, joints, and pipe connections.

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. The boiler comes on twice a day - morning and night. OD tubing. Gas control is a safety device. Proper gas valve adjustment can save your home from a devastating fire. As for the gas valve it is probably a "general controls" valve but any 800 millivolt gas valve can be used as a replacement. You may have to wiggle it a bit before it comes loose. Gas valves exposed to high ammonia conditions, i.e., those used in greenhouses or animal barns may fail in one or two years. 6 terminals + 2 jumpers = 4 effective terminals = 4 nodes. 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! home heater furnace blower doesn't turn on [SOLVED], Goodman GM880804BNBA ignitor will not stay on. 0000062506 00000 n
