[F04] / [19]
(Current code / AI-NET)
Check code name
TD1 sensor error
Cause of operation
TD1 sensor Open/Short
This error code means detection of Open/Short of TD1 sensor.
Check disconnection of circuit for connection of connector (TD1 sensor: CN502, White) and characteristics of
sensor resistance value. (Refer to Outdoor unit temperature sensor characteristics.)
If sensor is normal, replace outdoor I/F P.C. board.
