An oven appliance for providing convection and microwave heating includes a cabinet having a chamber positioned within the cabinet. The chamber is configured for receipt of food items for cooking and has a plurality of walls including a top wall, a bottom wall, a back wall, and opposing sidewalls defining the chamber. At least one of the plurality of walls defines a plurality of apertures and a first duct in fluid communication with the chamber through the plurality of apertures. The oven appliance also includes at least one convection heating element for heating the chamber. Further, the oven appliance includes a convection fan in fluid communication with the first duct. The convection fan is operable to cause air to flow out of the apertures. Moreover, the oven appliance includes a convection motor having a motor shaft. The convection motor is operably coupled to the convection fan for rotating the convection fan about the motor shaft. The convection fan is electrically separated from the convection motor to prevent microwave energy from leaking from the apertures.
