Exclamation Trane XE-78 no heat

The system only blows cold air. I watched the startup sequence and the ignition glows red for a few seconds then fades. It does this a couple of times and then the blower turns on. I never see blue flames that would indicated the gas igniting.

Can you suggest what steps I should take next?

"a few seconds" is a vague comment. How many seconds does the ignitor have to heat up before shutting off?

Does the main burner gas switch on after the ignitor starts to heat up?
