Hi all, I have this strange problem with my 10yrs old fireplace. It started last winter when it just wouldn't start after working fine during the fall. I turn on the switch and it'll click and you can see the spark but no fire. I thought it was dead but last summer the kids hit the switch by mistake and it worked again. So we started using the fireplace again in the fall and everything worked fine. My wife can leave it on all night no problem. Just this past Christmas it got much colder and the fireplace acted up again. Turning it on only produces the clicking sound but no fire. Does anyone have any idea where I should look for problem? thank you.
