Dehumidifier displays H2 and may shut down or not start.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Room temperature below operating range, Faulty low-temperature sensor, Sensor not properly attached to coil, Control board misreading sensor

Safety: Unplug the unit before inspection.

Check room temperature: Ensure the space is warmer than the minimum operating temperature (usually 41°F / 5°C). Move the unit to a warmer room if necessary.
Inspect coil sensor: Verify the evaporator temperature sensor is firmly clipped to the coil and wiring is intact.
Replace sensor: If the sensor reads out of range at room temperature, replace it with an OEM Comfee part.
Control board: If H2 remains with correct room temperature and a new sensor, the main PCB may be defective.
