whirlpool gas dryer stopped heating what could be the problem

my whirlpool gas dryer model LGR6620PQ0 has no heat but has power to run fine. I noticed that the red glow from bottom of dryer isn’t there anymore. Please help as I have no clue about dyers. It worked perfect yesterday but today no heat
