Gave the stove a good cleaning and fired it up this fall. Ran great the first several burns. Now the stove won't ignite. Just replaced the ignitor last year with a new one that has a lifetime warranty. Thought the ignitor was bad but when I tried the stove the other day, it actually lit. Now it hasn't lit since then. Any ideas? I also just replaced the control panel last year. All wiring is proper and tight. Thanks!
