I have a Frigidaire Model GLEB27T8CSA Double Wall Oven. The lower oven's convection fan is not operating. The heating elements are fine and the door switch is fine since the light operates normally. I was hoping someone else has had this trouble and could tell me if it might be the convection relay on board for the lower oven or some other part. The lower over has been lightly used and I do not think it is the fan itself.

Please and thank you of course!

The fan is the most likely candidate, primarily because it is seldom used. I'd try to see how freely the fan turns by hand and compare it with the other operating one. The bearings may have gotten gunked up and all it requires is cleaning.
