No flames coming from furnace; control board replaced, smell gas

The furnace stopped working, you can tell it’s running, but no flames come out of the jets.

You can smell gas.

Tech came and replaced control board and one other piece (around $1000 total).

I believe he lit it by hand to jump start it (even though the sticker says not to). Worked for the day. Went to bed, woke up and it’s down again.

Thoughts?
