Is it correct to use "the" before "materials used in making buildings are"? 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 gas valve is the load.need to have current flow from one leg of the thermopilethrough the limit switch ( zero ohms ) througn the thermostat switch ( approx zero ohms on call for heat) through the coil of the valveand back to the other terminal of the generator. Otherwise, take the necessary steps to provide proper gas pressure to the gas control. Slip the compression fitting over the tubing and slide out of the way. Otherwise, take the necessary steps to provide proper gas pressure to the gas control. A contractor came by and gave it a crack at it and said it was the gas valve but I'm not confident that that could be the problem as from reading this post, the thermoCOUPLE should be swapped out first before assuming it is the gas valve as it is a more pricey unit to replace.

Assure the main burner primary air supply is properly adjusted for complete combustion (refer to the appliance manufacturer instructions). 4. One 3/4 inch straight flange assembly (with O-ring and screws). The combination of spring pressure under the second automatic valve diaphragm and the lack of outlet pressure holds the diaphragm firmly closed.
