Gas heater not working
Pilot lights are the element that help a heater to ignite.
Gas heaters, whether they warm up air or water in a home, rely on a pilot light to trigger the flame of the actual heater. If this pilot light ever goes out, the heater has no way of actually turning on to heat the water or air that your particular type of heater circulates to warm the house or other elements. Knowing how to maintain the heater and troubleshoot the everyday type of issues with pilot lights will help you avoid costly repairs.
Corroded Pilot Tip
Gas is funneled to the tip of a pilot light via a supply line that is connected to a natural gas or propane supply. As the gas passes through the tip of the pilot light, it is ignited by the action of the pilot light, which is either electronic or manual. Over time, this tip can become corroded with soot and residue, blocking the gas from exiting the tip. It must be cleaned to operate at full capacity. A toothbrush works well, but you can also run a piece of flexible wire in and out of the orifices on the tip to scrape debris off. You should check at least every six months for the best results, although your manufacturer may have a different suggestion.
Size of Flame
Most furnaces have an adjustment element on the pilot light that allows manual adjusting of the size of the pilot flame. The exact location of the adjustment element varies by heater and manufacturer, so always refer to your manual or the pilot light instruction label, which is usually near the pilot light on a wall panel. While ideally the adjustment screw or bolt never needs to be adjusted, over time situations such as accidentally turning it while cleaning or experiencing an earthquake can cause the adjuster to move. If you have a flame that is too small to ignite the burners, this could be the culprit. Adjust the flame size larger until you reach a point where it lights the burners as intended.
Another culprit for not a large enough flame is insufficient gas. Alternatively, the pilot light may not stay lit after initially being triggered. First, make sure that you have sufficient gas in your reservoir by checking the pressure gauge on your supply tank. Also, make sure that all of the gas supply lines are in the “open” position. Tanks generally provide enough pressure until the reservoir is completely empty of gas, but in some cases once you reach the last 5 percent of a tank, the pressure will begin to wane, and it can sometimes be insufficient to keep a pilot light lit for a long duration.

If the gas valve is getting 24 volts when the ignitor is at it's hottest, then it is the valve or the pressure to the valve. If it is not getting voltage then it is the control or if there is a limit in the low voltage line from the control to the valve it could be that. You need to phone another company and ask that company for your money back as that is something an apprentice with a volt meter could find
