Hoping that's it as it's an easy diy fix.
Been there, done that. YouTube has a bunch of videos on it. Easy to do. The other thing is that the door you have to access the insides has a switch on it that has to be depressed before the furnace will work (at least on mine) so be aware of that when you put the door back on. The detector can detect whether there is a flame. If not, it won't feed gas for obvious reasons. Easy to do, but if you are not comfortable, call a pro.
