It sounds like you all know quite a bit about Harmon XXV stoves. We've had ours since October 05 and have dealt with the noisy blower this whole time. Now a new problem has arisen. In the middle of the night last night a high pitched beeping sounds started. It seemed to beep every minute or minute and a half. At two o'clock in the morning, I just turned it off; it was scaring my lab. My husband and I have cleaned the stove thinking maybe there was ash someplace new, but after a thorough cleaning, it is still beeping every minute to two minutes. Sometimes it corresponds to the feeder; sometimes it doesn't. It's still scaring my lab. Called the dealer; they said they have no idea. It's not a scraping noise; it's a beep. Any ideas?
