Grill powers on but display is very dim or flickers; buttons may be unresponsive.

Safety first: Unplug the grill before accessing the controller or wiring.

Steps to troubleshoot dim display:

• Inspect harness connections: Remove the controller and verify that the main power harness and all peripheral connectors are fully seated.
• Isolate peripherals: With the grill unplugged, disconnect non-essential loads (e.g., igniter, fan) from the controller one at a time, then plug in and test. If the display brightens when a specific load is disconnected, that component may be shorted.
• Check for heat damage: Look for discoloration or burn marks on the controller board, especially near the power supply section.
• Replace shorted component: If disconnecting a component restores normal display brightness, replace that component (fan, igniter, etc.).
• Replace controller if needed: If no peripheral is at fault and the display remains dim, replace the controller assembly.

Note: Operating the grill with an unstable controller power supply can lead to unpredictable behavior; resolve the issue before cooking.
