If I reset the Satronic after the system has cooled the burner will fire, run for about 1 1/2 to 2 mins, then go out with the fan running on for about 30 secs, then go to lockout. I am able to reset the satronic, but the burner will not fire again for about 20 to 30 mins, when it will do the same again (go out after about 2mins with the fan running on for 30 secs.)

Any ideas please, as its getting colder again from tonight!
