To make your central air conditioner work, there are dozens of moving parts and components. The air conditioner cannot work sufficiently, or at all without these parts. The air conditioner cannot work efficiently, or at all without these parts. The air conditioner will eventually need repairs with so many parts that naturally decay over time and use. Before the progression is extreme with routinely scheduled maintenance that can catch problems early on, many of these repairs can be avoided or stopped, however. The common problems AC fans experience and the fundamentals of the central air conditioner fans in your Las Vegas Valley home is what we at Hal Mechanical would like to share today.
What Causes AC Unit Fan Motor to Stop Working?
There are two fans featured in a central air conditioner. One fan is located in the inside unit that blows cool air for your home, and the other releases heat from your home and is located in the outside unit that blows over condenser coils. The home cannot be cooled efficiently should either of these fans experience any fault. The reasons that these fans commonly do not work properly or at all are listed below.
1) Worn AC Contactor. In addition to the condenser fan motor, the compressor is controlled by an air conditioner’s contactor is a switch in which electricity flows in and out. It is common for the contactor to wear down over time, restricting the outside unit’s fan from functioning properly. To replace the contactor safely and easily, you need a professional HVAC contractor.
2) Bad AC Capacitor. The capacitor stores up energy that is used to provide power to your air conditioner’s fans. For quite a few reasons, your capacitor can go bad and stop working properly and it will then force one of your system’s fans to stop spinning. A bad capacitor will need a professional replacement, more often than not.
3) No Power to AC Unit. As opposed to air conditioner fan problems being the fault of the fan’s assembly, a power issue can be at fault. If the various parts of your air conditioner can overheat and trip your circuit breaker, the air conditioner can be forced to shut down, for example. If it continually occurs, you should have a professional inspect the unit as to the underlying cause, though if it happens occasionally, you can flip the switch at your circuit breaker back on should this be the cause.
4) Burnt Out AC Motor. Especially being prone to wear and tear, fans can burn out when they undergo too much stress. When the air conditioning unit is not properly maintained, they are even more vulnerable to excessive wear. A bad fan motor is a more serious issue that will either require professional repairs or a system replacement, depending on the age and condition of your system.
5) Air Filter Clogs. If your air filter is severely clogged and your indoor fan is working properly, the air that it blows will be completely blocked. Particularly if it sounds like your fan is working but you don’t feel any air in your home, check your air filter and replace it if it’s dirty.
6) Loose or Snapped AC Belts. The fan to stop spinning properly in older systems with belt-powered fan can be caused from belt can get loose or break. It can also be an indication that a new air conditioning unit is in order since you likely have an older, less efficient unit where this issue can be repaired.
