Need help with non working furnace

Racine near Garfield, Chicago IL

Description

My furnace will not stay on. It’s throwing a error code. I can send you the code upon asking. I’ve changed the gas valve and the flame sensor. I was told to check the igniter but that was changed a year ago and looks good. I have a Payne furnace model number Pg8maa024070ADJA I’m here at the place now. The first person that can get here will have the job
