Intermitted Burner
I have a p-m336. I get intermitted burner fire. When I start heater I get cfh then spk. Pilot lights, but burners do not. I have cleaned everything I know of including connections. Have not found the gas pressure switch to see if this is the problem. Had the burners to light once, but when I put everything back together it would not work again. Any help?
