  • An air conditioner is a critical part of any homes HVAC system, particularly in areas that experience warm climates throughout the year. It keeps living spaces cool, improves air quality, and minimizes exposure to disease-causing allergens.

    However, AC systems are prone to malfunction like any other equipment. Sometimes, they stop spinning, making it challenging to keep your home cool. Identifying the cause of the problem is the first step. The next part of the article highlights why your AC fan is not spinning and the possible remedies.

    Why Is The Heat Pump Fan Not Spinning When The Unit Is On

    If you find that your heat pump is on but the outdoor fan isnt turning, there could be a few issues at play. Outdoor debris can get into the system and clog it. It is important to have a clear area around your heat pump year-round. If you see something that is lodged in your heat pump fan, turn off the power and then see if you can dislodge it with a tool or a stick. Never stick your fingers in a fan.

    Sometimes you can push-start your condenser fan by giving the blades a push. If that works, it could be a sign of a bad fan motor that will need to be replaced soon. If your fan does not move with a push, then you should have it repaired immediately. Do not run your heat pump without a working fan as that could cause damage to the compressor. A damaged compressor can lead to a very costly repair bill or replacement of the entire system.

    How To Tell If Your Ac Capacitor Is Bad

    Outside Ac Unit Fan Not Spinning

    As noted, the capacitor provides the power needed to start the cooling process. If the capacitor is faulty, you are likely to notice one or more of these symptoms:

    • The air conditioner is buzzing but not starting
    • Delayed cooling after turning the system on
    • The AC unit starts shutting off at random
    • The AC is refusing to turn on
    • A hike in energy bills
    • The vents release warm air while the AC is supposed to be on

    Any of the above signs should alarm you. However, it is best to look out for more than one symptom to rule out other problems such as clogged vents, a faulty blower, a dysfunctional condenser, or an aging compressor. Different systems operate using different mechanisms. If your system has a heat pump, it may work differently from other types.

    The most important thing to look out for is a fan. If the fan is not running and the humming noise is coming from the unit, then you can be certain that you have a faulty capacitor.

    You can visually inspect the capacitor once you have identified the problem. In most cases, the capacitor will have a slightly puffed-up top if it has gone bad. It may also be rusty or leaky. Once you notice any of these signs, be assured that the capacitor is your source of trouble.

    What Are The Signs An Ac Fan Motor Is Bad

    If the outdoor AC fan stops running, you may notice the results right away. Instead of oh-so-wonderful cold air, the air conditioner may push out hot air. Maybe the fan is running, but much slower than usual. Sometimes, you can still cool your house, but the AC has to work much harder to keep up, running a lot longer than usual. If you get a huge electricity bill, theres a good chance that an AC not working is the reason.

    The Importance Of Maintenance

    As you can see from our laundry list of diagnostics, poor maintenance is a common culprit in many AC problems. Setting up a routine maintenance contract with a trusted HVAC professional can keep your air conditioner in working order, preventing costly repairs down the road. A professional can also advise you of the maintenance tasks youll need to perform yourself, such as changing filters. Proper maintenance will also make your air conditioner more efficient, cutting down on your power bill and helping extend the service life.

    Both The Ac Compressor And Ac Fan Are Not Working

    If no sound is coming from the compressor and the fan isnt turning, then you may not be getting power to the unit itself and your AC fan is not working. Check the obvious first. Is the breaker to the unit tripped? If so, use the thermostat to turn off the unit and reset the breaker. Then turn the unit back on at the thermostat and see if that corrects the problem.

    If that doesnt work, then the problem may be with the compressor contactor. This is a part of the unit that sends power to the ac fan motor and the compressor. You should not try to fix this yourself. Call a professional Phoenix air conditioning repair company to get the work done safely.


    Signs And Symptoms Of A Bad Ac Fan Motor

    how to fix a humming non functioning air conditioner

    The air conditioner fan is located in the condenser unit . Therefore, to determine whether or not this part is working, youll have to walk outside and look at the fan through the vents of the condenser unit.

    Signs that your fan is having issues include the following:

    • The fan wont start even though the AC is on
    • The fan wont stop, even when you shut the AC off
    • The fan turns on, yet the blades are rotating very slowly
    • Theres a rattling noise coming from the condenser unit when the fan is turned on

    That being said, it could be tricky to figure out whether the issue is the fan or the capacitor since the capacitor is the part that provides the energy for the fan motor to operate.

    One way to know for sure is to unscrew the side panel of the condenser unit . The capacitor looks like a large, cylindrical battery, with cables connected to it. Its top should be flat. If it looks swollen, the issue is with the capacitor. If its flat, you could narrow down the malfunction to the fan.

    Fixing this issue as soon as possible is crucial, since having a faulty fan can shorten the lifespan of your AC compressor, resulting in the need to replace both parts. Purchasing a new compressor is substantially more expensive than replacing the fan.
