We just went through a Friday running on only the bottom conveyor because of issues with the top. I finally got the top running again about midnight last night and it turned out to be a minor issue that I should have caught earlier. While cursing the top oven last night with my burner tore apart on the dough table, I did some math in my head, then double checked it with a calculator. My top oven is over 10 years old, runs an average of 11 hours per day, seven days a week. That is over 40,000 hours of run time. Using rough estimates, the bottom oven which only runs during Friday and Sat rush or big orders has about 2000 - 3000 hours.
So, you guys running double stack conveyors, do you ever swap out the top and bottom ovens to get more balanced wear on the equipment?
By the way I have lincoln 1450’s and in ten years they have only seen a serviceman about 3 times. Every time we have had an issue it has been the burner control circuit module (2 times) or the pilot flame sensor needing cleaning (several times). I think its a pretty good record for that many hours.
