ERR7 displayed; grill temperature reading is extremely high or erratic even when grill is cold.

Safety first: Unplug the grill before working on wiring. Ensure the grill is cool.

Step-by-step checks:

• 1. Inspect probe and wire routing: Look for melted insulation where the RTD wire passes near the firebox or exhaust. Repair or replace any damaged sections.
• 2. Dry the connector: If the grill has been exposed to heavy rain or washing, disconnect the RTD plug at the control board and dry both sides thoroughly. Use contact cleaner if available.
• 3. Check for pinched wires: Ensure the probe wire is not pinched between panels or under the hopper, which can cause a short to ground.
• 4. Replace RTD probe: If visual inspection shows damage or ERR7 persists, install a new Grilla Grills-compatible RTD probe and harness.
• 5. Evaluate control board: If a new probe and harness do not resolve ERR7, the control board input may be shorted internally and require replacement.

When to call a technician: If you are not comfortable replacing the control board or working with electrical connectors, seek professional service.
