All parts guides
Browse by part family. Each guide explains what the part does, likely failure points, and what to verify before you approve replacement.
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.
Aircon outdoor reactor or choke
Some inverter outdoor units use a reactor or choke in the power path. Learn how reactor-path faults differ from IPM, outdoor PCB, and sensor faults.
Aircon outdoor run capacitor
A weak run capacitor can sound like a dead compressor. Learn which checks separate capacitor and compressor faults.
Aircon outdoor thermistor
Outdoor thermistor faults can mimic real heat shutdown. Learn which checks separate sensor error from heat stress.
Aircon outdoor unit bracket
Outdoor unit vibration and noise can come from bracket issues. Learn how bracket faults differ from fan blade, motor, and rubber support problems.
Aircon pipe insulation
Water dripping from aircon pipes can come from damaged pipe insulation. Learn how insulation faults differ from drain leaks, ice melt, and refrigerant problems.
Aircon power isolator switch
No power or unstable outdoor startup can come from an isolator switch issue. Learn how isolator faults differ from breaker, terminal, and outdoor PCB faults.
Aircon pressure sensor
Inverter cooling faults and unstable operation can involve a pressure sensor issue. Learn how pressure-sensor faults differ from gas leaks and outdoor PCB faults.
Aircon refrigerant system
Low refrigerant is often blamed for poor cooling. But a top-up without finding the leak is money wasted. Learn what we check before recommending any gas work.
