Abstract

A diagnosis control method of an air conditioner is provided to clearly inform a user of an air conditioner installation error. The diagnosis control method includes receiving a test run command or a self-diagnosis command for diagnosis of the air conditioner, performing a first test run to diagnose an assembly state of the air conditioner, performing a second test run to diagnose pipe connection of the air conditioner and an amount of refrigerant in the air conditioner, performing a determination including diagnosing a state of the air conditioner based on operation results of the first test run and the second test run, and displaying the diagnosis result through a display device provided at an indoor unit of the air conditioner.

Claims19

Dependent claims

An air conditioner comprising:

an indoor unit including an indoor fan, an indoor heat exchanger and a temperature sensor configured to detect a temperature of refrigerant at an inlet of the indoor heat exchanger;
an outdoor unit configured to be connected to the indoor unit by at least one refrigerant pipe, and including a compressor;
and
at least one controller configured to:
receive a test run command to perform a test run including a first test run and a second test run,
control the air conditioner to perform the first test run by operating the indoor fan of the indoor unit,
control the air conditioner to perform the second test run by operating the compressor of the outdoor unit, and
diagnose whether a valve of the air conditioner is clogged based on a first temperature detected by the temperature sensor before the compressor is operated in the second test run and a second temperature detected by the temperature sensor after the compressor is operated in the second test run.
