I'm wondering if you can help me with my Englaner pellet stove. The top auger does not turn. I swapped the wire with the bottom motor and then it turns. I jumped the vacuum switch leads together and it still didn't turn. So it will run if wired up to the bottom auger leads but will not run as wired from factory. It's less than 2 years old and the rubber hoses are sealed and still in great shape. Any idea on what could be wrong?
