I have a quda mt. vernon that I purchased brand new oct of 05. My question is do some of you replace parts before they go bad? I have been thinking of replacing my exhaust blower auger motor igntor and snap discs. I know it would be around 500.00 to do it. I have never had any issues with the stove but it runs all winter long it goes thiugh approx 5 tons a year it is my main heat source. so it gets a great deal of abuse. I just am not sure of the life span of these parts. All parts are origanal.
