Is ther a pilot light my roper rgs7648kq2 dryer is

All modern gas dryers use a hot surface igniton system(very old dryers had pilots). There could be a problem with the igniter,gas valve, ect. If you remove the bottom cover panel or inspection cap you can check to see if the hot surface igniter starts to glow when dryer is intially started. Just because the igniter does not glow does not mean that the igniter is the problem. There are two gas valves that work in conjunction with the ignition system as a safety(one could be defective). Also make sure that the gas connector at the back of the dryer is not restricted(kinked) and the gas line valve did not get shut off some how.
