I have an Austraflamm Integra FS pellet stove from 1992. It has always run great up until this season. Upon startup, nothing would work and the red light was blinking rapidly. I noticed there was some power going to the auger as it seemed like it was attempting to turn. I replaced the auger but the same issue appeared with the red light blinking and nothing running. I then changed out both the low and high limit switches. The stove actually fired up and ran great for 2 weeks. I gave it a thorough cleaning and went to re-start it when the blinking red light of death appeared and now nothing works again. Any suggestion?
