Crane dehumidifier displays E5 and shuts down; may coincide with frost on the coil.

Safety first: Unplug the unit before accessing internal components.

• 1. Check room temperature:
  • Ensure the dehumidifier is used within the recommended temperature range (typically above 41°F/5°C).
• 2. Inspect evaporator and sensor:
  • Remove the cover and inspect the evaporator coil for heavy ice buildup.
  • Locate the defrost sensor clipped to the coil; ensure it is firmly attached.
• 3. Allow manual defrost:
  • Turn off and unplug the unit; allow all ice to melt completely (may take several hours).
• 4. Replace sensor if needed:
  • If E5 returns quickly and the sensor is properly placed, replace the defrost temperature sensor.
• 5. Control board check:
  • If a new sensor does not resolve E5, the control PCB defrost circuit may be faulty and require replacement.
