Oster Reduced Fan Performance

Oster air fryer fan speed seems unusually low; food cooks slower and less evenly than before.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Grease buildup on fan blades, Worn fan motor, Low voltage from control board, Obstructed air intake or exhaust vents

Safety: Unplug and cool the unit before cleaning or accessing the fan.

Clean vents: Remove dust and grease from all exterior vents with a brush or vacuum.
Clean fan blades (advanced): Access the fan assembly and gently clean blades with a damp cloth to remove grease that adds drag.
Check motor: If the fan still runs slowly and feels weak when spun by hand, replace the fan motor.
Control board: If the motor is good but receives low voltage, the control board may be failing and should be replaced.
