York furnace issue

[Philipk66]

Hi, I have a 17 years old York Diamond 80 unit barely used since I live in coastal CA.
I was working fine now does do anything. Did all the usual trouble shooting.
When I pull the panel and push the safety shut off button there is 1 red flash for a one second
then nothing after that. Any ideas? Thanks! Kevin

Try turn ng off power then turn it back on at the breaker panel.
