Fujitsu General Error Code E:06

Fujitsu General Error Code E:06 generally indicates an outdoor coil temperature sensor fault. This can cause overheating protection shutdowns, poor cooling performance, or inconsistent operation.

The outdoor coil sensor monitors heat transfer and helps prevent compressor damage. If it fails, the system may stop to protect itself or run inefficiently. Causes include sensor failure, wiring faults, corrosion, or weather exposure affecting components.

If your system runs for a short time and then stops — or cooling performance drops — E:06 should be inspected.
