Why Is My AC Fan Motor Hot And Not Spinning

6. Dezember 2021 | Air Conditioner

Why is my AC Fan Motor hot and not Spinning? Is a question that air conditioning owners ask themselves more often. To ensure that this doesn’t happen to you, check out our blog post on how to prevent this issue!

What Is A Condenser Fan Motor?

Air conditioners and ac units use condenser fan motors to remove hot air from the air conditioning unit. This process is done through a sequence of steps: first, coolant is pumped out of the ac unit and sprayed with high pressure across fins (usually metal). The heat from this process causes warm air around it to be removed by force. The cooled air is then sucked into the ac unit and blown over cold pipes, cooling the liquid refrigerant. The refrigerant is then pumped back to the ac unit to start the process all over again.

A condenser fan motor helps this process by blowing more air across the fins of the condenser coil. Without a working condenser unit, the ac unit will not be able to remove hot air and will eventually overheat.

AC Fan Motor Hot And Not Spinning: What’s The Problem?

Several things could cause an ac fan motor not to spin. One of the most common problems is a blown fuse. The fuse for the ac unit is usually located in the breaker box, and it’s important to check this before doing anything else.

If the fuse is not blown, then the problem may be with the ac fan motor itself. The ac fan motor may have a broken or loose wire, defective bearings that are worn down and making noise, or the ac fan blade might be bent.

If the ac unit is not blowing air out of any vents at all when you turn it on, then there probably isn’t power getting to the ac unit. This could mean that there is a problem with the breaker or that the ac fan motor itself has burned out.

In any of these cases, it’s important to call a professional to diagnose and repair the ac fan motor. Trying to fix the ac fan motor yourself can be dangerous if you don’t know what you’re doing.

But there are other causes that can trigger this problem.

Bad Capacitor

If the ac power supply is not reaching the ac unit, the capacitor has a possible issue. A capacitor stores electricity and helps supply ac to the ac system (it acts like a battery). If the capacitor fails or becomes damaged for any reason, this could affect your ac fan motor as well.

You may also have issues with capacitors if you are trying to use multiple air conditioners together on one circuit. This can overload the circuits in both units, so make sure each ac fan motor has its own dedicated line before plugging them into opposite ends of the same breaker box!

The ac fan motor capacitor is an easy fix if you are comfortable working with ac wiring. Just take the ac unit’s cover off and find the capacitor, which should be labeled. The terminals of capacitors are generally marked + or – or have a + or – printed on them somewhere. If you can’t tell which terminal is which, it’s best to leave it alone and call a professional.

Once you have identified the terminals, use a screwdriver to remove the wires from the bad capacitor. Be very careful not to touch the wire ends together – this can create a spark and cause an electric shock. If you have trouble getting the wires off, you can try gently prying them off with a flat head screwdriver. Once they are loose, the ac unit capacitor will most likely slide out of place with no problem.

You can then install a new ac fan motor capacitor by putting the wires back in and twisting them back down to make sure they aren’t exposed (or touching each other). If you replaced your ac fan motor, you might also want to replace the capacitor. Just make sure the new one is rated for the same amount of volts and amps as your old one.

Burn-out Motor

Burn-out Motor AC Fan Hot and Not Spinning

Another ac fan motor problem that can cause ac units not to work properly is a burned-out ac fan motor. There are various components in the ac unit itself, and some of them come with specific life expectancies – if one part fails or becomes defective, this also affects other parts as well.

If your ac unit has been working fine for years, but all of a sudden it’s starting to blow warm air instead of cool air (or vice versa), then there might be something wrong with the system within the ac unit itself rather than just having an issue with how much power reaches it.

The electric current may be weaker overall due to problems like overloaded circuits or bad wiring somewhere between where you plug the breaker box and the ac unit in. Other electrical devices that share a common line with your ac unit can also trip the breaker if they’re using too much power. This is why you should always try to have as many things plugged into different breakers as possible so that each device has its own dedicated circuit!

If you’ve tried all of these fixes and nothing has worked, then it might be time to call in a professional ac fan motor repair service for help. These professionals can also help you figure out what’s causing your ac unit problems – and they’ll do so quickly and efficiently!

A Faulty Belt

If your ac fan motor isn’t spinning, there may be something wrong with the belt. The belt connects the ac fan blade to the motor, and if it’s broken or loose, this can cause all sorts of problems.

It’s important to check the belt regularly and make sure it’s tight and in good condition. If it’s not, then you’ll need to replace it. You can usually find the belts for ac units at your local hardware store.

Remember that ac units are heavy, so be careful when replacing the belt yourself! It’s always a good idea to call in an HVAC professional if you’re unsure how to do it.

Blocked Air Filter

If your ac fan motor is hot and not spinning, it’s possible that the air filter is blocked and needs to be cleaned or replaced. This can happen over time if you don’t clean or replace the filter regularly.

An ac unit with a clogged air filter won’t blow cool air properly, and it will also use more energy than it should. Make sure to check your air filter every month and clean or replace it as necessary!

So those are some of the most common causes of ac fan motors not working properly. If you’re having this issue, try some of these solutions and see if they work for you. But remember, if none of these fixes work, then it’s best to call in professional assistance.

Lack of Maintenance

Lack of Maintenance

If the ac fan motor is hot and not spinning, a lack of maintenance may be to blame. If you’ve ignored ac unit problems for years, then it could just stop working one day.

Remember that ac units need regular cleaning and maintenance to work properly. You should clean the ac filter regularly and check on all other components in your ac system about once per month so they don’t develop any other issues while waiting for repairs. If ac motors or other parts are already starting to fail or malfunction, these problems will only worsen if you continue to wait around before getting them looked at by a professional!

The best thing to do is call an ac fan motor repair service as soon as you notice any problem with your ac unit. If you practice good ac unit maintenance, then this will be less likely to happen in the first place!

Broken Fan Blades

Lastly, if the ac fan motor is hot and not spinning, one or more of the fan blades may have become broken or bent. If this is the case, you’ll need to replace the fan blades.

Fan blades can be replaced relatively quickly, and you can generally find them at your local hardware store. Just make sure that you buy the same size and type as your old ones!

Again, if you’re not sure how to do this yourself, it’s always best to call in a professional ac unit repair service. They’ll be able to help you get your ac unit up and running again in no time!

So those are some of the most common causes of ac fan motors not working correctly.

What To Do When Your AC Fan Motor Is Hot Or Not Spinning?

So, what do you do when your ac fan motor isn’t spinning, and it’s too hot to touch? The best thing to do is turn off your ac unit immediately and call a professional. Trying to fix the bad fan motor yourself can be dangerous if you don’t know what you’re doing.

The professional may tell you that the ac fan motor needs to be replaced, or they might try to fix the problem for you on-site. Either way, it’s essential to get this issue resolved as soon as possible, especially during the summertime when the weather is warm!

AC motors are one of those appliances where it’s always best to call in a professional. Many times, multiple things can go wrong, and it’s not always easy to diagnose the issue without the proper tools and knowledge. Ac fan motor repairs are one of those things that are best left to the pros.

How To Prolong The Life of Your AC’s Fan Motor

There are a few things you can do to prolong the life of your ac fan motor. First, make sure that the ac unit is properly sized for your home. If it’s too small, it will have to work harder than necessary and could eventually overheat.

Second, keep the ac unit clean and free of debris. This includes leaves, dirt, and other objects that can get caught in the fins of the condenser coil.

Third, don’t let the ac constantly run all day long. Try to schedule breaks throughout the day to cool down for a little while.

Fourth, keep an eye on your energy bills and see if they’ve increased since you installed a new ac unit. It might be time to have your ac unit replaced if they have.

Finally, avoid placing objects in front of the ac vents so that air can flow freely into and out of the ac system. If you need to place something near an ac vent, make sure it is fire resistant.

It’s important not to try repairing ac fan motors without knowing what you are doing because this could result in further damage or even injury if done improperly! Call a professional for help diagnosing and repairing ac fan motors today.


Air conditioners and ac fan motors can be extremely complicated appliances, and issues like ac fan motors not spinning or ac fan motors getting hot aren’t always easy to diagnose. If your ac fan motor isn’t working properly, try some of the solutions listed in this article, but if those don’t work, then you should call a professional ac repair specialist to have the ac fan motor repaired for you.
