I have a Model 140 Jenn Air Grill-Range with Self Cleaning Radiant Bake and Convection Oven installed in 1986. I have not used the Convection Oven as every time I turn it on there this rattle like the fan or some part of the fan is hitting something.  Has anyone else run into this?  Was it difficult to correct?
