I agree with those that say replace the module. I had a S310 a 2007 model I lived in a high humidity, rain, and cold with snow area. And I had to change mine out after about 7 years. Mine was a east/weat burner model but it plays the same the module is not a weather proof component.I am with Larry in that I would just buy a whole new igniter module. You can get the whole thing for twenty something dollars on Amazon. After 10 years it is time for a new one in my opinion.

Great rifle I have it also, perfect for small game.I pull a chair up in the shade with a nice cold Iced Tea and sit there with my Ruger 10/22 and subsonic rounds across my knees.
I have not noticed any propane smells or chew marks on the hose yet LOL - a rubber snake by the propane tank would probably scare me every time I go to light my grill.... I think I might go with the plastic trash panda to keep the squirrels away from key areasAgreed....those vermin are all well in good if they stay in their habitat.....but once they enter our attic...garage....cars....or even grills they can start causing big expensive problems. If they frequent your grill often u can do things to keep them away.....keep grease trey clean for one.....but I believe moth balls and or a plastic snake or plastic racoon might do the job. I keep a rubber snake and 2 way oversized rubber rats on my boat while it is under cover.....I dont wanna jinx my success so I will just leave it at that.
