To classify a problem with your outdoor AC unit, you need to escalate how your central unit works. Your home has something in mutual with the walls of your refrigerator. They both cover the cooler air that the AC unit holds ups into your home. Your outdoor air conditioning unit has two fans. The one on the inside of the unit blows cold air into the house. The one on the outside blows air crossways the coils to remove the heat from the air to cool it. When either of these fans is not functioning properly, the efficiency of your unit cooperates.
It’s easy enough to figure out if the AC unit fan not spinning on your AC unit. You can walk outside and listen for a droning sound to tell you that the blades are rotating. You can also visually appraise whether the fan is working. If you hear the hum but don’t see the edges moving, you may have a capacitor problem.
If you observe the AC condenser fan not rotating on your outdoor air conditioning unit, the difficulty is likely one of a few common things.
- If the compressor is working, but the fan won’t turn, then the problem is most possible with the motor and/or capacitor.
- If you don’t hear any sounds to designate that the compressor is waged, and the fan isn’t spinning, the most common reasons are a lack of power or a defective compressor contactor.
Inside your air conditioning unit, the fans turn with the support of motors and capacitors. You can think of the motor on a fan just like the motor in your car. Its job is to reason motion, and that motion transfers the air. If the outside AC fan won’t spin, the whole unit is operative incompetently or not at all. Without the fan, the trained air doesn’t get stirred throughout your home the way it should keep the hotness and humidity under the resistor.
If the motor is similar to an automobile’s engine, the capacitor is similar to the battery. The capacitor stores up energy to transmit out its responsibilities. The two most shared types of capacitors are the run and start variabilities. As you can estimate from the names, run capacitors keep something running, while start capacitors deliver a gust of energy to the motor to start the fan. Inside your AC unit, capacitors are opposite to the indoor and outdoor fans and the compressor. The cause each constituent has a capacitor is that getting the fan to start turning necessitates more energy than keeping it spinning.
When capacitors fail, it’s typically because they lose their aptitude to hold a charge. Over time, the capacitors merely don’t recall energy as well. When you add in factors like experience to risky heat or high power, you can see how easy it is for outside factors to cause this type of harm as well. To evade having your outside AC unit fan not spinning defensive upkeep is the best way to go. Also, if the capacitor goes out on an honest new unit, check your guarantee documentation. Most companies do deliver coverage for the capacitor for a limited date of time.
The issue with Bad Capacitor
One possible reason for your AC unit fan not spinning is to stop waged is a bad capacitor. The capacitor is a small, cylindrical device that delivers energy to your AC unit’s motor. It is answerable for starting up the AC unit and providing extra power as wanted to keep the unit running.
Signs of a bad capacitor include:
- AC having distress turning on
- AC closing off on its own
- AC not gusting cold air
- AC makes droning sound
The Broken Motor
The condenser fan motor on your AC unit is what tries the blades of the fan to setback outside air across the AC condenser coils. This process changes hot refrigerant gas into a cool liquid, eventually providing cool air for your home. A faulty motor is a common offender when your AC unit’s fan stops spinning and should be amended or replaced directly since it will affect your whole system’s presentation.
Having Contactor Problems
An AC contactor is a small device that panels the flow of electricity throughout your AC unit. When you set the temperature on your thermostat, these small parts are accountable for leading and limiting the electrical flows that tell your air conditioner whether or not it should operate.
Often sufficient, contactors burn out due to normal attire and scratch or if your system overheats. When a contractor burns out, the electrical movement of your system is reserved and the adjacent AC components will not obtain electricity, producing them not to function.
Contactors can also become wedged in an “up” or “down” position. When stuck in the “up” position, the electrical flow is congested between gears, whereas contractors stuck in the “down” position will continue running electricity to their components even when the cooling cycle is theoretical to end.
If your AC fan has stopped spinning, it may be because the contactors controlling power to your AC fan are stuck in the “up” position or are burnt out. Proper upkeep is vital to keep your contactors in healthy working condition, but sometimes reparation might be necessary.
A Broken Belt
Fresher AC units don’t rely on a belt system but in its place use direct motors. However, in older units, a broken belt might be accountable for your fan not working correctly. As AC belts age, they become more vulnerable to fraying, tearing, and other injuries. If your belt has gone bad it will make rare clanging, clicking, or harsh squealing sounds. A broken belt will avoid your system — including the AC fan — from working properly.
The Wrecked Fan Blades
Another likely reason your AC fan isn’t operational is due to smashed fan blades. The fan blades are generally noticeable through the openings of your outdoor unit. If any of the blades look bent, cracked, moveable, or otherwise damaged, we recommend keeping your system off until a licensed HVAC professional can check and repair the unit
