Kelvinator inverter split AC shows F2 and may shut down during operation.

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

Open or shorted evaporator thermistor, sensor not properly attached to coil, damaged harness, indoor PCB fault

Safety: Turn off power before working on the unit.

Steps:

Access coil: Remove front cover and filters to expose the evaporator coil.
Check sensor placement: Ensure the thermistor is clipped firmly to the coil tubing and not hanging loose.
Inspect wiring: Follow the sensor wires to the PCB, checking for damage or loose connectors.
Test and replace: Measure resistance; if out of spec, replace with a Kelvinator-compatible evaporator sensor.
