Hi my name is ***** ***** I might be able to assist you with some ideas on what you can do here. I'm assuming that you are talking about your fireplace insert that burns wood? You should be able to pull off one of the grills on the stove to get to the motor of the blower to clean it up. It is somehow controlled by a thermostat in the blower. The temperature of the burning wood is what turns the blower on, so are you doing anything differently this year from last year and therefore it's not getting hot as fast:
1) Maybe your wood is too green this year? This would cause the wood to burn slower and it won't be as hot a fire. You shouldn't be burning any wood that hasn't been seasoned for at least 1 to 2 years. Or is your wood overly dry (old)? Here's a good article that describes seasoning your wood: http://www.wikihow.com/Season-Firewood
2) Are you leaving the damper open to build up the heat of the fire, or has it been closed and you didn't notice it? The damper needs to remain open until you get a really good hot fire going.
3) Or it's possible that the switch on the blower is beginning to wear out and will need to be replaced soon?
I would check the first 2 suggestions first and see if that does the trick. If the blower is too loud, it may be time for a new blower too. But first you need to find it and it will probably be at the bottom of the unit.
I hope one of these ideas work for you. Let me know!
