Hey all, New to this madness... so my St. Croix pellet stove is 5 yrs old and Ive had zero problems up until now... Was blinking number 2 and shutting off, I cleaned the entire stove out and still the problem persisted, called up the local dealer and they came out and cleaned it again- fired it up and left. Guess what? in about a hour it cut off and started blinking 3 this time...... Another guy came out and messed with it for like 3hrs without a fix.... Said he will return in a few days for more diagnostics..... Any ideas? Its cold?? Looked up the faults- seems like a proof of fire, damper, augur problem.. Thanks for your help in advance!
