Applied deposit December 19, purchased December 26, delivered December 28, partially installed January 6, installation to working condition January 17.  Upper convection fan not operating…then screw popped out, fan started up & made very bad noise.
Frigidaire repairman arrived to repair today, February 1st…seemed to be minor fix to remove outer cover & reinsert screw.  So haven’t used the two ovens very much yet.  I believe they are working ok?  To clarify, this happened to the upper oven, obviously when on Convection Bake.
