Yes, the bin auger on my LMF Corn Furnace died yesterday. It was the original Gleason Avery motor. I figure it has moved about 100,000 lbs of fuel (50 Tons), not to shabby.
Anyway, I had a new spare 2rpm motor on hand and swapped it out. Back up in running in less than an hour. What I have noticed, in the last 24+ hours is that I am getting way more heat now. Both motors were 2rpm. I am thinking the old one was getting a little tired.
Normally when we are in the mid to upper 20's the tstat will stay at where you set it with the furnace going into high fire occasionally. For instance, I set ours at 67 when sleeping and not at home and 69 when i am home. This morning I was at 72 and at lunch I was at 73-74. And again this evening I was at 73. The furnace is just idling away and providing more than enough heat for us.
On a strange note I am happy the auger failed.
Maybe something to keep in mind if your older unit is not delivering as much heat...
