If your CPU fan does not spin, the issue could be anywhere from the fan, the motherboard, to the power supply unitpower supply unitThe efficiency of a computer power supply is its output power divided by its input power; the remaining input power is converted into heat. For instance, a 600-watt power supply with 60% efficiency running at full load would draw 1000 W from the mains and would therefore waste 400 W as heat.https://en.wikipedia.org › wiki › 80_Plus80 Plus - Wikipedia. The fan can get clogged with dust and lint hence preventing it from spinning. The same problem could originate from the PSU (power supply unit) if it is not able to output the 5V or 12V to power your fan.

Why is my outside AC fannot spinning?
One of the most common reasons fans stop spinning is because of a dead capacitor. Each air conditioning system has several capacitors, including the start capacitor, which sends signals to the motor, and the run capacitor, which keeps the motor running. Capacitors can go bad over time and need to be replaced.
What causes condenser fan to stop running?
There are several reasons the capacitor of your HVAC unit can fail. These include overheating, running too long, power surges, and age. When the capacitor fails, the condenser fan will no longer rotate.Aug 9, 2019
What happens when the condenser fan motor fails?
However, a condenser (outdoor) fan-motor failure can be even worse. Since the refrigerant isn't being condensed, it causes the pressure on the discharge side to get very high and the compressor (since it isn't being cooled) gets extremely hot, which breaks down the internal lubricant and contaminates the system.
What do you do if your AC fan wont spin?
Turn off the AC from the thermostat and the circuit breaker. Check the fan for any debris or components it is contacting while spinning. Using your kick-start stick to manually spin the fan makes this easier. If you notice any debris, clear it out, turn everything back on, and listen to it again while it's running.
Why is my outside fannot spinning?
If the fan doesn't start running, you may have a bad fan motor. If you have difficulty getting the blades to turn, there may be debris wrapped around the fan axle, or the motor bearings may be dirty or jammed.
How do I reset my outside air conditioner fan?
- Power down your AC. Start at your circuit breaker panel and flip the breaker that powers your AC.
- Find the button. Most air conditioning units are equipped with a reset button.
- Hold down the reset button for 3 to 5 seconds and then release.
- Restore power to your AC.

Why is my condenser fan stopping?
One of the most common reasons fans stop spinning is because of a dead capacitor. The AC's capacitors are small, cylinder components that send energy signals to power the fan motor and the rest of the AC unit. Capacitors can go bad over time and need to be replaced.
Why is the fan on my outside AC unit not running?
If the fan doesn't start running, you may have a bad fan motor. If you have difficulty getting the blades to turn, there may be debris wrapped around the fan axle, or the motor bearings may be dirty or jammed.
What to do if AC stops spinning?
The air filter might be clogged, and you need to clean or change it. Another cause of an AC unit fannot spinning is a clogged air filter. If you can't remember the last time you replaced the unit's filter, it's time for a replacement. This is an approachable solution for homeowners to tackle.
What does it mean when the AC fan outside not spinning?
If the compressor is working, but the fan won't turn, then the problem is most likely with the motor and/or capacitor. If you don't hear any sounds to indicate that the compressor is working, and the fan isn't spinning, the most common causes are a lack of power or a faulty compressor contactor.

How much does it cost to replace an AC fan motor?
When your air conditioner's fan motor breaks, it will typically cost about $300 to $600 to replace. It's imperative to get this fixed quickly, since without a working fan motor your air conditioner's compressor can be the next domino to tumble. Its repair is even more significant — usually running closer to $2,000.
Where is the blower motor reset button?
Locate the reset button on the furnace and press it to reset the furnace. It is usually located inside the blower compartment on the side of the blower motor. Be cautious as the housing may be hot. If the button is popped up, press it down.
What controls the AC condenser fan?
The condenser fan relay is the electronic relay that controls the power to the AC condenser cooling fan. The AC condenser is designed to cool down and condense incoming refrigerant vapor into cooled liquid and uses the fan to help keep it cool. The fan's power is controlled by the condenser fan relay.Jan 5, 2016
How do I know if my HVAC blower motor is bad?
- AC Fan Doesn't Start. Even though you have the AC turned on, the fan does not start.
- AC Fan Doesn't Stop.
- Slow Rotating Blades.
- Outside Fan Blades Are Still.
- Rattling, Humming, and Buzzing Noises.
- AC Runs Intermittently.
- No Cold Airflow.
What controls the condenser fan motor?
The contactor is a switch found inside your HVAC unit that controls the voltage distributed to the compressor and condenser fan motor.Aug 9, 2019
