Last Jan '12 my auger of 11 years gave out. The first gear stripped. So I replaced the auger in my Whitfield Advantage II in about 5 min and 15 min. later the house was getting warm again. But this winter it seemed the stove never gave a big fire.. plus this new auger was a bit noisy. Well just over a year and this replacement auger is making a awful sound and no pellets. This Merkle-Korff auger motor gave up the ghost. From what I can see, the outer layer on the motor is spinning around on the shaft... quality. I'll have to post photos on my web site. So I happen to have picked up two more spare motors off E-bay back in 2009. They have wires to their motor but I just shoved the wires into the old connectors and 15 min later I have heat. I'll have to get the right connectors over the weekend. The new replacement motor is stamped ECM, can't see any other markings. This one is absolutely silent.
