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.
Aircon remote control
Remote not working does not always mean the indoor unit is faulty. Learn how remote-control faults differ from IR receiver and indoor PCB faults.
Aircon Schrader valve core
A tiny service-port valve core can cause slow refrigerant leaks. Learn how Schrader valve core leaks differ from service valve and flare-joint leaks.
Aircon service valve
Poor cooling or post-service cooling failure can come from a service valve issue. Learn how service valve faults differ from flare-joint leaks and deeper refrigerant faults.
Aircon start capacitor vs run capacitor
Understand how start and run capacitors differ in a home aircon, what failure patterns look like, and what should be checked before replacement.
Aircon suction line
Learn what the suction line does, what pipe sweating or line temperature signs can mean, and what to check before repair decisions.
Aircon terminal block and wiring connection
Burning smell, on-and-off startup, or breaker trips can come from hot terminal connections. Learn how this differs from capacitor and contactor faults.
