The only other thing that would cause this issue would be a faulty gas valve that would need to be replaced.

Thanks for your help @Ed_C_APP_Team .

If I can remove the Dryer Igniter and Igniter Sensor and they show no signs of installation, is it possible for them to be returned for a refund or am I just out of luck?

Asking as I’m confused by the “We will gladly offer a full refund minus shipping costs on products that are new and have not been installed or show signs of installation” clause on Cancellations & Returns - AppliancePartsPros.com - seems as if it should say “We will gladly offer a full refund minus shipping costs on products that are new and have not been installed or show no signs of installation”?
