Disgnostic step (Aircon not cold)
Fundamental Concept:
When it feels warm while your hand is placed right at the outlet, it means, the air conditioner is not producing cold air at all. It cold be due to:
a) a faulty indoor pcb that doesn’t send a request to the condenser, or
b) the condenser receives a signal from the indoor unit, but is not processing it, or
c) a faulty starting capacitor that doesn’t kick start the compressor, or
d) a compressor that runs out of gas (gas leak), or
e) a faulty compressor, or
f) the compressor has overheated and shut down, or
g) the outdoor fan motor is jammed or spoilt, or
h) the outdoor condenser is choked
Remarks:
When an air conditioner is not producing cool air, it can be caused by a number of factors. Most people jump to the conclusion that it has run out of gas. Nevertheless, this is the least probable of all. Ranked highest is in fact: “c) a faulty starting capacitor that doesn’t kick start the compressor” for a non-inverter system
Nevertheless, we will guide you step by step to help you streamline what exactly had gone wrong.
Systematic Troubleshooting :
Step 1:
Make sure that the remote controller is set to the “cool” mode or the snow flake icon.
Step 2:
Can you see the front of the condenser? Is the fan turning? Note: if you cannot see the front of the condenser, take a
piece of paper and put it on the condenser fan coil;if the fan is turning, it will suck the paper towards it.
Is the fan turning?
