An Aircon blower motor is like the heart of your air conditioning unit. It blows cool or warm air through the air vents into your home. This motor makes sure that indoor air keeps moving, spreading the air all around your room or house.
There are typically 2 blower motors in a air conditioning system. The indoor twin shaft blower and the outdoor single shaft blower(s). These blowers are usually 240V three speed units that uses a capacitor. Overtime, the capacitor ages and deteriorates, which is the main cause of motor burnouts.
Recognising the early warning signs of a failing AC blower motor can save you from a motor burnout and unexpected costs. If your system is struggling to circulate air efficiently, it’s time to investigate potential causes and seek solutions that ensure a breath of fresh air for your indoor environment.
Your AC unit not blowing air could mean trouble. Weak airflow or none at all often points to a blower motor that needs help. Dirt and lack of oil can cause this problem, as they lead to mechanical resistance. This makes your fan work too hard and it might stop moving air like it should. If you notice the air is not coming out strong from your vents, take action quickly. This sign tells you that something’s wrong inside where you can’t see. Blower motors don’t fix easily; most times they need replacing when they act like this. Keep them clean and well-oiled so cool air keeps flowing as it should in your home or car.
Blower motors can get too hot if something is wrong. Heat may build up because the motor works too hard or has a problem with its parts. You might notice this if your air conditioner starts to feel warm instead of cool. Strange sounds from your blower motor are not good news either. These noises could be telling you that the inside parts, like bearings, are wearing out. If you hear scraping, whining, or rattling coming from where the air comes out, it’s time to check on your blower motor.
