I have a Harmon P 68 pellet stove that’s approximately 12 to 13 years old. The distribution blower seems to not be working properly. No fault lights are illuminated. The stove is feeding the hopper and I have a nice flame but no matter what temperature I put the stove on the flame gets bigger, but the distribution blower does not move the air.I have it set on room, temperature, auto ignite. I recently cleaned the stove out because it was making a weird noise. Any advice is appreciated.
