York Stellar Plus won’t ignite
Natural gas furnace, 12 years old, small, only heats 2 rooms, photo with upper part door open here:

Sticker says model # M3UF024SA, can’t find it anywhere.
Situation:
When heat is switched on motor starts running, pressure switch (the one on the right with 2 wires) closes (multimeter reads 0V), but hot surface igniter won’t ignite.
Disconnected the igniter and there is no voltage coming in to igniter contacts.
Igniter itself looks OK, not broken, a little charred, ordered new one just in case.
No diagnostic LED here, like our other unit York Diamond 80 has.
Question:
What could be the problem, can I test further myself or call a pro?

Found answer to the problem on another forum, thermal switch(fuse) was bad. Waiting for the part now.
