Have new stove for 1 month that was bought online. Ran great for 2 weeks 4 bags or so. Did not run it for a week and now I am getting saftey smoke alf1 after about 1 minute on phase 1. My flue is not blocked and only 12 feet long. My hopper switch is not the problem. There is a small area of door gasket 1 inch max that appears to have some burn damage otherwise no other ideas as to what may be the cause. Any help would be appreciated. If anyone knows anybody in northern Wisconsin that works on these also would be great. Thanks.
