gas valve not working:
Sounds like you may have a leak in your flame-tube (fire) box. This
is where the gas burns. Outside the flame tubes is where the air
flows, picking up the heat and bringing into the house distribution
ducts. There are sensors to detect leaks. Leaks would allow gas and
combustion products to leak into the ducts, so if a sensor thinks
there is a leak, it shuts the gas. If your unit is more than 10 year
old, this may be the problem.
