Gas valves are an integral part of any furnace. They supply fuel to the burners, which enables ignition to take place. Gas valves have many integrated safeties in place to prevent dangerous failures. This can sometimes make them difficult to diagnose. Keep in mind that there are two key factors that need to be checked when diagnosing a valve.
The final thing to consider when dealing with gas valves is the “on” and “off” switch which is located on most valves. Be sure that this switch is turned “on” when attempting to light the furnace. Many technicians have wasted many hours and good gas valves due to overlooking this simple switch.
