Ive got an Austoria that I purchased new about 11 years ago, Recently I replaced the auger bearing, about 6-8 weeks ago my house filled with smoke and lazy flame. I did a deep cleaning and replaced the combustion motor with an OEM unit, worked great for 6-8 weeks, this am at 6am, same thing, house was filled with smoke and lazy flame and smoke coming out of the heat tubes, Luckly I installed a smoke detector to alert us, What else would cause the blower to stop working ? Thanks for your help in advance
