Fujitsu Ducted Air Conditioner Replaced with New Daikin FDYAN160A-C2V in Seacombe Gardens
7 August 2026When your ducted air conditioner suddenly stops working properly, it doesn’t always mean the entire system needs replacing. Sometimes, a thorough diagnosis can pinpoint the failed components and get the system back up and running with a targeted repair.
That was the case for Sam in Kidman Park, whose LG ducted air conditioning system was having trouble keeping the home comfortable.
The Problem
Sam contacted Morphett Air after experiencing problems with his LG ducted air conditioning system.
Our technician carried out diagnostic testing and found the lower condenser fan motor was faulty.
During testing, the outputs from the PCB were found to be correct, helping rule out the PCB as the cause of the problem. The fan motor could also still be spun by hand; however, it failed resistance testing, confirming a fault with the motor itself.
Rather than simply replacing parts based on symptoms, testing allowed our technician to identify where the fault was occurring and determine what was required to repair the system.
The Repair
Once the problem had been diagnosed, the necessary replacement parts were organised to get Sam’s LG ducted system operating correctly again.
The repair included:
● Replacement of the lower condenser fan motor
● Replacement of the fan motor harness
● Replacement of the fan blade
● Replacement of the disposable air filter
With the faulty components replaced, the system could be returned to operation and provide heating to the home once again.
Before and After
Before:
The LG ducted system had a faulty lower condenser fan motor. Although the PCB outputs tested correctly and the fan could physically spin by hand, the motor failed electrical resistance testing.
After:
A new lower fan motor, harness and fan blade were installed, along with a new disposable filter, getting the system back up and running.
Happy days — Sam’s all warm again! ☀️
Repair or Replace? A Proper Diagnosis Matters
An air conditioner fault doesn’t automatically mean you need a completely new system.
Depending on the system’s age, condition, availability of replacement parts and the nature of the fault, repairing an existing ducted air conditioner can still be a practical option.
That’s why proper diagnosis is important. By testing the system and identifying the failed component, we can give our customers the information they need to make an informed decision about whether to repair or replace their air conditioner.
If your ducted air conditioner isn’t heating, cooling or operating as it normally should, the Morphett Air team can diagnose the problem and recommend the appropriate next step.
