Hi,

cannot find how to relight the pilot light for the gas
You would need to go back approax 20-25+ years to find a dryer with a standing pilot light. All now are are an hot surface ignitor to light the gas, The ignitor is feed power and the ignitor glows red hot to ignite the gas.

Igniter kit

There will be a small square plastic plug on the front of the dryer near the bottom...with the plug removed this is a view point so we can see inside to find out if the ignitor is comming on or not.
