Help! I have a gas dryer that is now having a problem. Its not WICKED old and worked fine up to recently. When I opened it up and ran it, the gas fired up fint the first time. Then when it cycled off (thermostat) and tried to re-fire, it did not ignite. It has an ignition "glow" wire that glows red, then a click (gas valve?) then...nothing. The barrell spins fine, fan blows fine, no restrictions in the exhust, etc. Should I replace the gas valve? Let me know. Thanks a lot!
