Hello, I have a Kinderhook FS pellet stove . The stove is three years old and came with the house i just bought. I had a stove shop do a seasonal clean out and go through the stove.It is wired to a thermostat and the mode is on auto/off. I have had no issues till last night it went off and the red light was flashing on the heat output indicator. The stove was running on the lowest heat setting. I couldn't find an error code for this in the manual.I unplugged the stove and vacuumed it out (usually done every 2 days). When i plugged it back in it started up, i raised the temp setting up to the second level and its been running now for about 20 minutes. What does the flashing red light mean on the heat output indicator? Thanks, South Shore
