PROBLEM

POSSIBLE CAUSE

SOLUTION

Poor cooling
performance

Air volume

normal

Compressor
operates

Operating near minimum or maximum of
operating temperature range

Review room environment

Dirt in indoor or outdoor heat exchanger

Clean heat exchanger

Frosting on the refrigerant line caused due
to blockage

Service refrigeration
system

Insufficient refrigerant

Check for leaks, repair,
and add refrigerant
based on the weight
listed on speciﬁcations or
nameplate

Poor cooling
performance

Air volume
normal

Compressor
does not
operate

Low voltage

Repair power supply

Capacitor malfunction
See “Inspection of Parts” on page 42

Replace capacitor

Resistance of compressor coil is zero or
inﬁnity due to a short or open circuit

Replace compressor

If power supply, capacitor and compressor
are normal, there is a problem with relay
board

Replace relay board

Air volume
abnormal

No air

Fan motor malfunction
See “Inspection of Parts” on page 43

Replace fan motor

If fan motor is normal, there is a problem
with relay board

Replace relay board

Air volume
insufficient

Clogged air ﬁlter

Clean air ﬁlter

Clogged indoor or outdoor heat exchanger

Clean heat exchanger

Crushed ﬁns

Repair or replace heat
exchanger

Improper duct connection
(Optional accessories)

Adjust duct connection

Abnormal rotation of indoor or outdoor fan
motor

Replace fan motor
