But if unfortunately, your air conditioner outside unit fan is not working, you should get in touch with a professional and ask for help. Another crucial component of your air conditioning system is the capacitor. The small but potent gadget stores energy utilized to operate the inside and outdoor fans on your air conditioner. The fans may stop spinning if the capacitor malfunctions.
They usually stick open, never sending the signal to the motor. This is much easier and less expensive to repair than a motor going bad. The blower wheel may also be clogged with dirt or debri, as shown below.
AC Fan Not Working? Here’s The Likely Culprit
If there is no flame in the furnace, then the furnace will shut down to prevent unburned gas from leaking out. Another common reason for your AC fan not working is a bad capacitor. It also speeds up the repair process when you can correctly articulate your issue with your local HVAC technician. Your outdoor fan is what transfers the heat from your home to the outside air and is located within the outdoor unit. Make sure to turn off your furnace, air conditioner, or any electric device when troubleshooting to avoid safety hazards. While you’re at it, check if there is rust in the pipe and if there is soot in your furnace.
According the Department of Energy, 78⁰F is a good setting for both comfort and energy efficiency when you are home. When your AC unit is not installed correctly, then your fan will not work. The reason why you must ensure the company you hire knows how to install your AC unit properly is because this can affect the wiring. This means your unit’s parts won’t be getting the power they need to do their job, which can be why your AC fan unit is not spinning outside. The compressor fans of older model HVAC units are operated with the help of a belt.
The AC Contactor Is Not Working Correctly
A furnace switch may be located on the unit itself or on a nearby wall. Because it looks like a regular light switch, it could be turned off by accident. Simply put the switch in the On position and you’re good to go. It then becomes a must-have for safety and comfort at home. It may be tempting to try to service the AC yourself. However, being tempted to save yourself a buck can cost you more serious damage to your cooling system and run the risk of complete system replacement.
One capacitor starts the motor, and the other sends standard voltage to keep it running. Unfortunately, capacitors wear out with time and often need to be replaced before the end of the life of the air conditioning system. The capacitor’s job is to store power used to operate the fan motor in the condenser unit. Occasionally, these components fail which prevents the fan motor from receiving proper power as the system runs. Have your HVAC technician replace the capacitor and this fix should correct the outside AC fan not working. Look inside and see if any fan blades are bent, broken, or missing.
Furnace Not Working? Here’s What to Do
You shouldn’t perform this task with your hands because even when at the moment, your central AC fan is not spinning. AC fan won’t turn off and runs continuously without stopping, it could indicate a severe technical problem and call HVAC professional technician. Though a burnt-out motor seems like a serious problem, it actually presents an excellent opportunity. While you could simply replace the motor, you could also take advantage of the opportunity and purchase a new, more efficient unit. Your first thought is to figure out what’s going on and if there’s a way to get it started again without scheduling a service call.
A drain snake can also be shoved up the pipe to dislodge the slime from the drain line. If all else fails, then a drain gun is a last resort to force the clog out of the pipe with high pressure. This small device often burns out due to normal wear and tear or if your AC overheats.
Get notified about company news and be the first to get early access to HVAC, Electrical, Plumbing and home maintenance tips and tricks. A good maintenance schedule can avoid many of the problems listed above. Spending a little bit of extra time ensuring your AC is in good working order can pay dividends in the long run. Testing the contactor risks electrocution, so if you are uncomfortable testing, leave it to the experts.
The evaporator coil sits inside your home within the air handler unit , pulling heat and humidity from indoor air as it passes through. The evaporator coil can freeze up as a result of indoor blower fan malfunction, low refrigerant charge, low outdoor temperatures, or other system malfunctions. The disconnect box is a small box located close to the condenser unit.

Some homeowners have noticed the door will slightly open again. If that happens to you too, that’s a sign you need professional repair. This is not a complex problem to fix, and your HVAC technician will be able to sort it out for you quickly and affordably. However, if the belt is giving you trouble regularly, it could be time to replace the AC unit.
The mere presence of a belt drive in your condensing unit means the system is old, and it’s time to think about upgrading your air conditioner. Newer versions of air conditioner units do not use belts; instead, they use direct drive components to automatically connect the fan and motor. Now you know potential reasons why your furnace fan isn’t working and how to troubleshoot and solve the problem. Remember that fixing the issue early is critical as left unchecked, furnace blower motor issues can transform into more serious problems.

If the circuit breaker continues to trip, you may need an electrician or an HVAC specialist to come and sort the matter out. The good news is that you don’t need a professional to check out if your AC fan is not spinning. You only need to walk out of your house, and if you see that your AC unit fan is not spinning, you found the problem. This issue can originate from a capacitor malfunction, bad installation, a compressor breakdown, or a damaged condenser. But, before taking an in-depth look into each of these possibilities. You need to understand what each part of your AC unit does.
Do not attempt to replace the run capacitor yourself. If you have a battery-operated thermostat, make sure that the battery isn’t weak or dead. If it’s electrically operated, then you’ll want to make sure that the circuit breaker hasn’t tripped. Sometimes this is all that’s needed to reset your unit and get the heat flowing once again. Air conditioner fans not working can be a sign of a frozen evaporator coil.
