Gas oven not igniting but smelling gas
Actually everything is working. This kind of gas oven, that uses the Hot Surface Ignitor / Igniter, can take up to 25 seconds to fire the gas.
After turning the oven knob:
Between 0-5 seconds, I don't see anything happening.
Between 5-15 seconds, you see the igniter getting brighter (orange color).
At some point after 15-20 seconds, you finally have fire.

Coming from a gas with a pilot light, I was used to have close to instantaneous fire as soon as you turn the oven knob (because there is fire, pilot light, already).

Thank you all!
