My Payne Gas Furnace, most of the time will not light correctly. Usually, 2 of the 4 jets will light and then it shuts down and attempts a restart. If all 4 jets do fire, then it will run for around 3 min and then just shuts off with the blower still operating. After 2 -3 min, it starts over and tries to refire. Is there a problem with the valve to the 2 jets?

There may be a rupture in the gas passage to the unit, or dirt in the valves most likely this , a service by a qualified engineer should resolve your problem, do not attempt this yourself unless you have good knowledge of what you are doing you may blow yourself up and others around you, DANGER!
