American Standard (Trane) Freedom 90 Furnace will not fire up no heat
My furnace will not fire up (American Standard or Trane Freedom 90) at all. When I turn the gas switch to on and then turn on the power switch I hear a click and then nothing, no other noises, no glow or ignition or anything. If I set the thermostat to have the fan on then the fan does come on and runs. There are lights on the control board so it is getting power. A friend has suggested the control board may be bad and to replace it but I thought I would get a second opinion here just in case. I would hate to replace a part that isn’t the problem. I attached some pictures for reference on the type of furnace it is. I think the red light blinks twice so it is “locked out” but turning the power off (resetting it) even for several hours doesn’t seem to get it out of this mode. Or maybe I’m reading the lights wrong. Any help is greatly appreciated!
Edit: I added a video of the startup code. I really hope it’s not the control board because I can’t find the replacement part it may be too old to buy a new one.
