If your outdoor AC unit fan isn't running, it's likely due to a power or electrical issue. The thermostat may not be receiving the power it needs to send a signal to the outdoor unit to start the fan.
The circuit breaker or fuse may have tripped or blown, causing the fan to stop running. This is often the case if you've recently experienced a power outage or surge.
Check the circuit breaker or fuse box to see if the breaker has tripped or the fuse has blown. Reset the breaker or replace the fuse to see if it resolves the issue.
If you've checked the circuit breaker or fuse box and everything seems fine, the problem may be with the electrical wiring or connections. Check the wires and connections to the outdoor unit for any signs of damage or wear.

Troubleshooting
Troubleshooting is a great way to identify the cause of your outdoor AC unit fan not running. Just remember to exercise caution and avoid any situations compromising your safety around electrical components or refrigerant lines.
A bit of hands-on troubleshooting can potentially save you both time and money. Before escalating to service calls, try to resolve some basic issues yourself.
If your outside AC fan stops working, it will be easy to notice by peaking into the condenser from above. The fan sits near the top of the outside AC unit.
Listen to the unit from the outside to ascertain if you are suffering from a bad fan motor. If you hear a humming noise, it means the fan blades are working.
If you hear a hum but notice the AC unit fan not spinning, then there could be one or more things wrong with the unit.

Power Issues
A tripped circuit breaker or blown fuse can easily cut electricity to your outdoor fan, causing it to not spin. This is usually an easy fix, just flip the switch back on at your circuit breaker box.
The breaker box contains high voltage, so it's essential to treat it with care to avoid an electrical jolt. If you're not comfortable around electrical systems, it's best to call an electrician or HVAC technician.
Loose or corroded wiring connections to the unit can also cause power issues. This is another reason your outdoor fan might not be spinning.
If the circuit breaker continues to trip, you may need a professional to come and sort the matter out.
Electrical Problems
Electrical problems can cause your outdoor AC unit fan to stop running. Faulty capacitors, tripped circuit breakers, and blown fuses are all potential showstoppers that can bring the system to a halt.
Tripped circuit breakers and blown fuses are common electrical issues that can prevent the fan motor from receiving the power it needs to operate. Corrosion on electrical terminals can also cause problems as units age.
Faulty capacitors, like small batteries that store power to start the fan, can fail over time, preventing the fan from spinning. The start capacitor provides the burst of energy needed to get fan blades going, and the run capacitor delivers a smaller amount of current during operation.

Faulty Contactor
A faulty contactor can be a major electrical problem in your AC unit. This electrical switch controls the compressor and fan motor in the outdoor air conditioner cabinet.
The contactor can fail over time, preventing these components from receiving the electrical power they need to operate. This can cause the fan motor not to run.

If the contactor fails, it can prevent the fan motor from receiving the power it needs to spin. The condenser fan won't spin either.
You might hear a humming noise from the unit if the contactor is faulty. But if the fan blades aren't moving, it's a sign that something is wrong.
Electrical
Electrical issues can be a major headache when it comes to your AC system. Faulty electrical connections can cause the entire system to shut down.
Frayed, loose, or corroded connections can be found in the wiring leading to the fan motor, and faulty capacitors may also be visible and failing. This can happen over time due to wear and tear.
Tripped circuit breakers, blown fuses, and loose connections all qualify as potential showstoppers for your AC system. Corrosion on electrical terminals provides another common impediment as units age.
Disruptions in the voltage supply can bring the whole system to a halt. Exercise caution around live currents and always follow safety guidelines when working with electrical systems.

Failed Capacitors
Failed capacitors can be a major issue with outdoor AC fans, causing them to malfunction or not start at all.
These tiny batteries, which store power to start and run the fan, can lose their ability to store energy efficiently over time.
The outdoor environment can be tough on capacitors, exposing them to dust, dirt, wind, and moisture that can cause damage.
In fact, damaged fan capacitors are a fairly common problem, especially in AC units over ten years old.
Proper maintenance can help prevent this issue, but even with regular maintenance, capacitors can still fail due to wear and tear.

Inspect Condenser Unit
Inspecting the condenser unit is a crucial step in identifying electrical problems. Regularly check for any obvious obstructions preventing fan movement, and remove dirt, foliage, or critters blocking the blades.
Power should be off before inspecting the unit to ensure your safety. Carefully remove any dirt, leaves, twigs, or other debris that may be accumulating around the fan.
Environmental contamination can cause fan blade rotation issues. Dirt, leaves, twigs, and other detritus can accumulate over time, interfering with normal fan blade rotation.
Grass clippings getting sucked against protective grilles can make matters worse. Weigh removing any shrubbery in close proximity to maximize airflow clearance.
Regular maintenance can resolve cases of impeded blade spinning. By clearing debris and obstructions, you can eliminate frequent culprits behind poor airflow.
Mechanical Issues
A mechanical issue with your outdoor AC unit fan is a common problem that can be caused by a faulty motor.
The motor could be worn out or damaged, which would require professional repair or replacement.
A worn or damaged motor can cause the fan to not spin, and it's essential to contact a local HVAC technician to diagnose and repair the issue.
The technician will be able to assess the motor and determine the best course of action to get your AC unit running smoothly again.
In some cases, a simple replacement of the motor might be all that's needed to get the fan spinning again.

Safety First
Dealing with electrical components can be extremely dangerous if handled improperly.
Shut off all power sources to the outdoor condenser unit before attempting any hands-on troubleshooting.
Always follow the manufacturer's instructions for disconnecting power to your AC unit.
Protection
Direct sunlight can damage condensing fan motors, accelerating component degradation and leading to premature failures. This can happen whether temperatures rise or units ice over.
Installing a simple awning or compressor blanket provides ample shielding without restricting airflow. These shields can be a game-changer in protecting your equipment.
Applying fresh motor shaft grease annually is another easy step to take. This simple maintenance task can help fend off premature failures.
By taking these protective steps, you can significantly reduce the risk of equipment damage and extend its lifespan.
