I have an Englander PDVC 25 stove that was made in 2005. The stove has given me great service since I bought it. I've replaced 1 auger motor,1 convection motor and 1 exhaust motor in the past 15 years of service. All the motors made that tell tale screech that the bearings were done for. I replaced the combustion motor in 2009 because it had gone by. Last year I removed it and inspected the blower fins and there was some wear to them but not that much. But lately I've noticed a large build up of glowing pellets in the burn pot. I'm still getting an active flame however. Just wondering if the motor might be slowing down due to age and should be replaced.
