Possible Causes

Failed convection fan motor, Obstructed fan blades, Faulty convection relay on control board, Broken fan wiring

Safety first: Disconnect power before accessing the rear or interior fan cover.

Listen for fan: Start a convection bake cycle and listen for the convection fan. If silent, proceed to inspection.
Inspect fan: Remove the interior fan cover and check for obstructions or seized blades.
Test motor: Access the rear of the range and test the convection fan motor for continuity. Replace if open or seized.
Control board: If the motor is good but not receiving power, the electronic oven control may have a failed relay.
