T-stat is working...cause fan comes on
Fan is working cause cold air blows out registers
Sail switch is closing allowing DC to circuit board for ignition & gas valve opening (slight smell of propane)
So it sounds like:
Clogged burner slots----propane obstructed
Improper spark gap (1/8")-----no spark
Bad spark electrode-------no spark
Bad connection on wire from circuit board to spark electrode
Bad circuit board
NO you can not light it manually.
Can you hear the spark electrode fire.....CLICK, CLICK, CLICK?
What is the furnace BRAND/Model?
