Lennox Whisper Heat doesnt heat

I have an older Lennox Whisper Heat furnace that doesnt produce heat. I place the thermostat in auto and set the temp, but nothing. the fan comes on when placed on the fan mode, and when i place it manual. no matter what it does there is no heat produced. any suggestions would be great

Remove the upper door (bumped out one) and near the burner box there is a damper door, when the t-stat calls for heat, this door should open, then once that opens all the way, the ignitor should start sparking to light the pilot.

Report back on your finding.
