Fundamental Concept: When it feels warm while the outdoor condenser fan is turning. It means that the condenser is receiving a signal (please make sure thatthe rest of the air conditioners are turned off). It could be that the compressor is turning but had run out of gas (gas leak) or the compressor is not […]

Remarks:When the fan is not turning, it can be due to : a) a jammed / spoilt fan motorb) a faulty relay switch / capacitor / pcb Diagnosis : Do you hear the sound of the compressor turning? Yes: It is a fan motor related problemNo: It is an electrical/electronics problem)

Clogged Filter Fundamental Concept:The aircon is producing cold air, but it is not strong enough to reach you. Solution is to improve on the air flow. Systematic Troubleshooting (for layman): Step 1:Open the aircon lid cover, you wil see 2 pieces(usually) of plastic net filters. Step 2: Check if the filters are dirty. Yes, they […]

1st:First, make sure that you’ve got new batteries replaced. It takes very little electricity to show the display on the remote controller, doesn’t mean the batteries are OK. The batteries may be too weak to send the signal across to the air conditioner. 2nd :The same brand of air conditioner usually have more than 2 different  types […]

Determine if it is producing cold air Fundamental Concept:Cold Fan Coil  + Strong Airflow = Cool AirWhen your air conditioner is not cold, it can either be that your Fan Coil is not cold or the airflow is weak or both. Therefore, it is important for you to know if it will be a repair job […]

Common Causes: 1) An unbalanced aircon blower. a) The circular aircon fan is too dirty, the weight of the dirt may not be evenly distributed and thus causing the aircon fan to vibrate when turning. b) The balancing chips attached to the circular blower had rusted and dropped off, leaving the blower unbalanced. Or some blades were […]

Common Causes: 1) An unbalanced Condenser Fan blower. a) This is a very rare condition, but I’ve personally come across such before. Normally, the outdoor condenser fan has 3 fan blades. Should any of the fan blade breaks off, the fan will be so unbalanced in weight that it causes the entire condenser to vibrate vigorously. If […]

There are generally 3 types of power tripping: 1) It trips the ELCB (Earth Leak Circuit Breaker) or the RCCB (Residual Current Circuit Breaker). That’s the big circuit breaker with the blue lever. It is often installed on the left, the first one. It will be written ELCB or RCCB. If you are interested in what’s […]

Common Causes:Fear not! It may just be a very simple problem. This problem can be cause by a couple of  possibilities (ranking from the most probable): 1) A faulty miniature aircon ON/OFF switch. Most probable (and cheap to repair)2) A faulty aircon remote controller that keeps sending signal repeatedly.3) A faulty aircon PCB (printed circuit board, […]

You’ve spent a fortune renovating your house and after many years when the air conditioners are old. You’ll like to simply replace the air conditioners while keeping all the pipes. But, the pipes are leaking, and you wondered what had gone wrong? Pipe leakage is often caused by acid build up within the gas system […]
