I have a gas fire place that is operated by a switch (light switch). It worked fine until last year. I have the pilot lit, and when I turn on my switch, nothing happens. I have to open up the lower louver and hit the red ignitor switch a few times. Last year, I only had to do this the first time after turning my pilot back on. So far this year, I have had to do it every time. Is this a simple fix, or do I need a fixit guy?
