Instant Pot Voltage Sag / Internal Power Fluctuation

Air fryer display and lights flicker when the heater cycles on and off.

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

Weak household circuit, failing internal power supply capacitor, loose neutral connection, overloaded circuit

Safety first: Unplug before internal inspection.

Dedicated outlet: Use a dedicated outlet with no other high‑draw appliances to reduce voltage sag.
Check cord and plug: Ensure a tight fit in the outlet; replace worn outlets or plugs.
Internal board: Inspect the main control board for bulging capacitors or heat damage. Replace the board if components are failing.
Electrical evaluation: If flicker occurs with multiple appliances, have an electrician evaluate the home wiring.
