Possible Causes

Open or shorted ambient temperature thermistor, Disconnected sensor harness, Corroded sensor connector on control board, Damaged sensor from condensation

How to Fix / Troubleshooting

Safety first: Unplug the dehumidifier before accessing internal components.

  • 1. Locate the ambient sensor:
    • Typically mounted near the air intake grille or on the evaporator frame with a small clip.
  • 2. Inspect wiring:
    • Follow the two-wire harness from the sensor to the control PCB.
    • Ensure the plug is fully seated and wires are not pinched or broken.
  • 3. Check for moisture damage:
    • Look for corrosion or water marks around the sensor and connector.
  • 4. Replace sensor if needed:
    • If E1 persists, replace the ambient temperature sensor with a Crane-compatible thermistor assembly.
  • 5. Control board check:
    • If a new sensor does not clear E1, the control PCB may have a damaged sensor input circuit and require replacement.
