Teledyne Laars EPC-400 lights about 2% of the time I turn it on
My Teledyne Laars EPC-400. When I turn the toggle up, it makes a buzzing noise, clicks, and turns off. After about 50 tries it lights. When it fails, I checked the 25v to the controller and its present so the problem is not with the limits/fuses. The voltages to the gas valve change with the sound, and go back to 0. Any advice? Point me to a manual maybe?

You may want to pull your pilot assembly out and clean it. If you have one. Some of these had a problem with soot building up on the pilot and that would cause the ignition spark to flow threw the soot ball that would build and you would hear a buzz rather than a spark. So no spark no ignition. After it tries a number of times the soot will move enough to let it light, but will build more soot and make it worse for the next time. If this is the problem this will reoccur and you can just set yourself to clean it now and again or the replacement has been improved to allow mor air to keep it from sooting. I hope this helps, good luck.
