I own a buck 2700 purchased in 1988 and recently had the blower motor go out of it. I replaced the blower motor. immediately blower would run for maybe 1 minute then shut offf ..run 1 minute then shut off. Thought it was the CPI bar so replaced it with a brand new one.Motor still runs a minute then shuts off.Over and over. If I cover the air intake vent on the CPI bar side,stove works fine. Anyone else have this problem? If so, please advise how you fixed it. I appreciate any help. Thank you
