Air Conditioner

Error Code
Possible Causes
Solutions

F0

General/system fault or Controller/PCB issue

Fault in control board, invalid feedback, overall system error; could also be sensor feedback loop failed

Reset power, inspect control board for damage; if persists, service technician needed

E6

Communication failure or Protection limit exceeded

Indoor-outdoor communication faulty; sensor feedback missing; possibly overload or high temp protection triggered

Check communication wiring between indoor & outdoor units; reset unit; ensure ambient conditions are within spec

F1, F2, F3

Fan motor / Sensor / External component faults

F1 may be indoor sensor fault, F2 possibly outdoor unit sensor or ambient sensor, F3 might indicate something like tube sensor or similar

Identify which sensor/fan the code corresponds to; test it (open/short); replace sensor or fan motor if needed

H6

Jumper cap / Protective module / safety or limit switch

According to the AC manual I saw, H6 was “jumper cap malfunction protection” (something like a protection due to wrong configuration or hardware jumper cap issue)

Check hardware jumpers (if any) inside unit; check wiring harness to see if a jumper or cover is missing; call service if it’s internal module issue

P1 / P01

Pressure / Compressor or Refrigerant related

High pressure or low pressure in refrigerant cycle; issue in compressor protection; possibly clogged filter, refrigerant leak or overcharge

Check refrigerant levels; inspect filters & valves; get technician to verify pressures, replace or repair affected components

E1, E2, E3

Sensor issues / Temperature sensors open / short or misread

Indoor/Outdoor sensor open‐circuit, shorted sensor, wiring loose or corroded

Inspect respective sensors (ambient / tube), check their connections; replace sensor if reading out of range
