E15 error, audible alarm, unit may shut down cooling as a safety precaution

Safety: Unplug the appliance before testing sensors.

• Identify affected sensor: Refer to the service manual or wiring diagram to see which sensor triggers E15 on your model (cabinet, evaporator, or zone-specific).
• Inspect sensor wiring: Look for crushed or rubbed-through insulation where the sensor cable passes through metal or foam.
• Disconnect sensor: At the control board, unplug the suspected sensor. Measure resistance across the sensor leads. A reading near 0 Ω indicates a shorted sensor.
• Replace shorted sensor: Install a genuine Hotpoint NTC sensor and route the cable to avoid sharp edges and moisture.
• Check connectors for moisture: Dry any damp connectors thoroughly and correct the source of condensation or leaks.
• If E15 persists with new sensor: The control board input may be shorted internally and require replacement.
