Dryer cooling light on
Does not heat up.

Tried timed dry, still no heat.

tested and replaced ignitor
cooling light still on.
still no heat

tested radiant flame sensor, high heat thermostat (both are at the gas heating tube), both tested ok.

What am I missing to test? Is there another sensor?

Thanks everyone!
