After the ignitor heats up for 30 seconds or so, the ignition control module should turn on the 24 VAC to the electric gas valve which will cause gas to flow to the burners where it will be lit by the HSI.

If that's not happening, first check to be sure you have gas to the gas valve. All the gas valves should be open and the dial on the electric gas valve turned to on. Do you have other gas appliances and are they operating normally?

Once you are sure you have gas, use a multimeter to check to see if you have 24 VAC being switched on to operate the electric gas valve after the HSI heats up. If you do, you may have a bad gas valve.

If you don't, you may have a bad ignition control module.
