Dehumidifier shows E2 and stops, compressor does not run.

Safety: Unplug the unit before removing any covers.

• Check filter and airflow: A clogged air filter or blocked intake can cause abnormal coil temperatures. Clean the filter and ensure good airflow.
• Inspect coil area: If you can access the evaporator coil, look for the small sensor clipped to the coil tubing. Ensure it is firmly attached and not hanging loose.
• Check for ice: If the coil is iced over, allow the unit to thaw completely, then restart. Persistent icing may indicate a sensor or refrigerant issue.
• Internal wiring: Verify the sensor harness is fully seated on the PCB and not damaged.
• Persistent E2: The evaporator sensor likely needs replacement. This is a low-voltage part but requires partial disassembly; consider professional service.
