Display shows SEN or sensor error; grill will not maintain set temperature.

Safety first: Unplug the grill before accessing the control panel or wiring.

Step-by-step checks:

• 1. Inspect RTD probe: Check for physical damage, heavy buildup, or loose mounting inside the cook chamber.
• 2. Reseat connector: At the control board, unplug and replug the RTD connector several times to clean contacts.
• 3. Clean probe: Gently clean the probe with a soft cloth to remove grease and soot.
• 4. Replace RTD: If the error persists or temperature readings are obviously wrong, install a new Grilla Grills-compatible RTD probe.
• 5. Evaluate control board: If a new probe does not clear the SEN error, the control board may need replacement.

When to call a technician: For persistent sensor errors after probe replacement, seek professional diagnosis.
