Microwave displays PF or P0 after a power outage; clock may be flashing.

Safety first: Ensure your hands are dry when handling plugs or outlets.

• Reset the clock: Press CLEAR/STOP, then set the clock per the user manual. PF is usually informational only.
• Check power source: Confirm the outlet is working by plugging in another appliance. Reset any tripped breakers or GFCI outlets.
• Inspect power cord: Make sure the Oster microwave’s power cord is fully inserted and not damaged.
• If PF recurs frequently without outages: Have an electrician check the outlet and circuit. Persistent issues may also indicate an internal control board power-supply problem.
