I have a york stellar plus unit model number p2udd020n09501c.
I thought it was the thermostat. It does not turn on at all. Whether I switch it to cool or heat it does not turn on. I purchase a new thermostat thinking and hoping it is that. Well that didn't do anything as well.
I have no idea about this unit. Obviously I have no idea how the unit works. I am on a budget freeze now and winter is around the corner. Im at a lost here. Anyway of doing a diagnostic on this at least trying to find out what is wrong with this.
