So today I had a hell of a time trying to repair a lang 6valve griddle. I left with it still not operating at full capacity. Idk wtf is wrong with it, but it seems like everytime I touch something on it breaks even more. I believe the problemS with it are the flame sensors, because everytime I jump one of them with a jumper wire the main gas valve turns on and ignites that burner telling me the gas valves are fine on it. So I move a known working flame sensor to the inoperable one and it still doesn't seem to work and then the valve next to it stops working as well... Idk, I told them to buy a new one.
I never cant figure something out and fix it. I put 4hours into this thing and its defeating me. Guess it is time to break out the schematic for it and see how its wired.
