I have an Englander 25-pdvc and I know from touching my bottom auger motor it is hot enough to burn my finger. I'm also starting to see some grease leaking out of the bearing probably due to the heat. I then seen on the motor that it was Inter. duty on it. I have some experience in motors and this means intermittent duty and since the bottom auger turns all the time wouldn't that mean that it should be a continuous duty motor. My buddy has an older 25-pdvc stove and when I seen him we took his top auger motor out which never gets hot and applied 115 vac (no load) and after 20 min. it got so hot that even the gear box was getting too hot to touch. I looked into Merkle and sent an e-mail and the Englander part is a proprietary part and I couldn't get any info. I have seen from other websites similar motors/gearboxes. Don't get me wrong about the pellet stove, in general it works well and heats my 1500 sqft home. I'm thinking long term maintenance and costs. I bought it to save money. If I'm wrong about the motor please let me know. The above comments are observations only. I'm not a motor expert.
