How to Fix / Troubleshooting

Safety first: Unplug before accessing sensors or controls.

Steps:

  • Verify with thermometer: Place a reliable thermometer inside and log temperatures over 24–48 hours.
  • Check sensor placement: Ensure the cabinet sensor is properly clipped to its mounting point and not hanging loose.
  • Test/replace sensor: Follow E1 steps to test the NTC sensor and replace if readings are unstable or out of range.
  • Thermostat check: On mechanical models, replace the thermostat if it cycles erratically.
  • Control board: If sensors and thermostat are good, the main control board may be mismanaging cycles and require replacement.
