Dehumidifier displays F3 and stops dehumidifying; coil may not frost as expected.

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

Broken evaporator NTC sensor, Disconnected sensor plug, Wire break due to vibration, Corroded connector

Safety first: Unplug the dehumidifier and wear gloves when working near sharp fins.

Locate evaporator sensor: Find the sensor clipped to the evaporator coil or inserted into a tube on the coil.
Check attachment and wiring: Ensure the sensor is firmly attached and its wires are intact and connected to the PCB.
Replace sensor: If the sensor is open or physically damaged, install a new Hisense-compatible evaporator sensor.
