Possible Causes
Undersized or failing internal power supply, Loose AC connections, High resistance in power cord, Overloaded household circuit
How to Fix / Troubleshooting
Safety: Unplug the unit before internal inspection.
Steps to reduce display flicker:
- Dedicated outlet: Plug the Ultrean fryer into a dedicated wall outlet without sharing with other high-wattage appliances.
- Inspect cord and plug: Check for heat discoloration or looseness. Replace the power cord if suspect.
- Open base: Remove the bottom cover and tighten all AC input screws and connectors.
- Board evaluation: If flicker persists, the low-voltage regulator on the main control board may be failing. Replace the main control board.
Warning: Persistent dimming of lights in your home when using the fryer may indicate a household wiring issue; consult an electrician.
