Oster Erratic Control Input / Electrical Interference

Oster air fryer time or temperature settings change by themselves during cooking.

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

Moisture on touch panel, Faulty touch controller, Electrical noise from nearby appliances, Loose control board ground connection

Safety: Unplug the fryer before opening the control housing.

Dry touch panel: Ensure the panel is completely dry and free of grease. Do not operate with wet hands.
Relocate appliance: Move the fryer away from high-power devices (microwaves, induction cooktops) that may cause interference.
Inspect grounding (advanced): Check that the control board ground connection to the chassis is secure.
Replace touch panel or board: If settings continue to change without user input, replace the touch control panel and, if needed, the main control board.
