Aircon filter
A blocked filter is the most common cause of weak aircon cooling. Learn how to check yours, when to clean it yourself, and when a service visit is needed.
Aircon filter drier
Some refrigerant repairs involve a filter drier in the refrigerant path. Learn how filter-drier issues differ from leaks, metering faults, and compressor-side faults.
Aircon flare joint
Slow gas loss can come from a leaking flare joint. Learn how flare-joint leaks differ from coil leaks and service valve leaks before any top-up is recommended.
Aircon float switch
Aircon keeps shutting off from a drain issue? Learn how float switch faults differ from drain blockage, drain pan faults, and other shutdown causes.
Aircon four-way valve
On heat-capable systems, a four-way valve can affect mode switching and cooling behavior. Learn how four-way-valve faults differ from compressor and control faults.
Aircon indoor fan motor
Weak room airflow can come from motor fault or blocked filters. Learn which checks separate the two.
Aircon indoor PCB
Indoor PCB faults can look like wiring or sensor problems. Learn which checks confirm board failure.
Aircon indoor thermistor
Indoor thermistor faults can cause early cut-off and warm rooms. Learn which checks confirm if replacement is really needed.
Aircon indoor unit insulation foam
Indoor sweating and drip patterns can come from damaged internal insulation foam. Learn how insulation-foam faults differ from drain leaks and coil icing.
Aircon interconnect communication wire
Indoor and outdoor units must pass signals through the interconnect wire. Learn how communication-wire faults differ from PCB faults and terminal connection faults.
Aircon inverter power module (IPM)
No cooling, trips, or unstable inverter behavior can involve the inverter power module. Learn how IPM faults differ from outdoor PCB, compressor, and sensor faults.
Aircon IR receiver
Remote commands not reaching the indoor unit? Learn how IR receiver faults differ from remote battery issues and indoor PCB faults.
Aircon liquid line
Learn what the liquid line does, how it differs from the suction line, and what pipe signs can and cannot prove.
Aircon louvre swing motor
Swing flap not moving or stuck in one angle? Learn how louvre swing motor faults differ from vane linkage jams, remote issues, and indoor PCB faults.
Aircon louvre vane linkage
Flap movement problems can come from broken louvre linkage parts. Learn how vane linkage faults differ from swing motor faults and command issues.
Aircon noise filter (EMI filter)
Some outdoor units use an EMI or noise filter in the power path. Learn how EMI filter faults differ from fuse, isolator, and outdoor PCB faults.
Aircon outdoor fan blade
Outdoor noise, vibration, or weak heat release can come from a damaged fan blade. Learn how fan-blade faults differ from motor faults and bracket vibration.
Aircon outdoor fan motor
A failing outdoor fan motor traps heat in the system. Learn which checks confirm motor-related failure.
Aircon outdoor PCB
Outdoor PCB faults can look like compressor failure. Learn which checks confirm board failure.
Aircon outdoor PCB fuse
No outdoor response can come from a blown outdoor PCB fuse. Learn how fuse faults differ from terminal, PCB, and power-switch faults.
