Ambient temperature sensor or cabinet temperature reading is out of range; E14 displayed.

Safety first: Disconnect power before accessing internal sensors and wiring.

Steps to diagnose:

• Locate ambient sensor: Find the Champion ambient or cabinet temperature sensor (often a small probe near the control area or air intake).
• Inspect wiring: Check for damaged insulation, loose connectors, or corrosion at the sensor terminals and along the harness.
• Measure sensor resistance: With the sensor disconnected, measure resistance at room temperature and compare to Champion’s specification chart. Replace the sensor if readings are out of range or intermittent.
• Check for moisture: Dry any condensation around the sensor and connectors. Ensure the control compartment is sealed properly.
• Evaluate control board: If a known-good sensor still triggers E14, the control board input may be defective and require replacement.

When to call a technician: Board-level diagnosis and replacement should be performed by a qualified technician.
