Display shows 'PF' or power failure message; cooking cycle stops unexpectedly.

Safety first: Unplug before inspecting the cord or internal components.

• Check the outlet: Plug another appliance into the same outlet to verify stable power. If it flickers or loses power, have the outlet inspected by an electrician.
• Inspect the cord: Ensure the Instant Pot air fryer plug is fully inserted. Check the cord for damage, kinks, or burn marks. Replace the cord if any damage is found.
• Avoid overloading circuits: Do not run the air fryer on the same circuit as other high‑draw appliances (microwave, toaster oven) to prevent breaker trips.
• Internal check (advanced): Open the housing and inspect the power input connections and internal fuse. Tighten any loose spade connectors and replace a weak or heat‑damaged fuse with the correct rating.
• Control board: If PF occurs frequently on a known‑good circuit with a good cord, the internal power supply on the main control board may be unstable and require replacement.

After resolving the cause, restart the cooking cycle; most models will not automatically resume after PF.
