Wondering why your air conditioner isn’t working well and the coils are frozen, made you curious about how to fix an air conditioner fan motor? There are five easy steps in doing so, and these things you will know as you further read the article.
Air conditioning units are a must-have for everybody around the world, especially for hot and sunny days.
They are ideal to own since they use the heat around you. An internal fan does the majority of the work. First, it suctions hot air into the system’s interiors, where it is then converted to cold air with the help of the coil.
We don’t often realize when they have been overworked because of our air conditioning systems’ energy when they are continually utilized. If ever that happens, then maybe there is something wrong. Thus, you should check your appliance right away once you noticed that it isn’t working well. Good thing you’ve come to the right article.
For people who are having problems like yours, we can help you out with that. Let us teach you how to prevent happenings like this; keep reading to know more about it.
Methods That We Can Do To Fix An Air Conditioner Fan Motor
How to fix an air conditioner fan motor? Air conditioner fans play an essential role in your AC unit’s internal system; without the fan working, it can cause the evaporator coil to freeze and break. You should check its parts frequently as you may not notice that it is slowly breaking because of over-usage. As much as possible, set a time for usage.
If you want your air conditioning unit’s fan to operate correctly, you should always listen for any sounds; with that, you’ll be able to tell if it’s working this way.
Suppose you have your unit’s handbook, then good. Try to go through some of its sections carefully because it could include some helpful information that we might use later. There are some necessary parts that you should know about your air conditioning unit’s internal system so, if you do not have a handbook, you can base from here.
Once you’re done dealing with these, we can assure you; there will be no more problems that you’ll have to deal with anymore. Then, you can have the well-deserved rest that you’ve needed after a long tiring day of work and all. Below are a set of methods that you can use to work efficiently and with ease. In addition, you can use it as a reference so you won’t have a hard time dealing with it.
Step #1. Learning the structure of your air conditioning unit
As we’ve said earlier, it is essential to know about your air conditioner’s external and internal parts; familiarizing it will be a big help if you’re new to this. The condensing unit and the evaporator coils that reside in the plenum of your furnace are the two primary components of an air conditioning system.
Condensing units play a significant role here. They are the ones to blow the air from outside onto the coil to remove the heat. Without it, the evaporator coils may freeze, and your air conditioning system won’t work the same way ever again.
Step #2. Cleaning the condenser coils
Before anything else, the first thing you should always do is turn off the power of your appliance. We want to avoid any injuries while cleaning your AC’s coils. Condenser coils are usually located outside, making it a perfect place to clean off the dust build-ups. So now, what you want to do is take a garden hose with you.
And aim it to the upper part of the coil to remove the build-up of dust around your condenser coils. Repeat this on the other sides and ensure that there is no remaining debris left around the unit.
Step #3. Testing the fuses
Two cartridge fuses are found in many disconnect blocks. Therefore, before you start repairing, you should double-check them to ensure. Usually, a blown fuse indicates that a component inside the condensing unit is deteriorating. With that, you should replace almost all the parts to avoid issues.
Using a multimeter, set it to the lowest Ohms scale and let both red and black leads touch at the ends of the fuse. If it indicates a numerical reading, then your fuse is good; If not, that shows a broken fuse.
Step #4. Removing and replacing the run capacitors
Now what you’ll want to do is first discharge the capacitors by simply removing them from the retaining bracket. Then, using an insulated screwdriver, touch the HERM. Then repeat this step by touching it between the FAN terminal and the C terminals.
Once you’ve done it, please take a photo to use it as a reference for reconnecting the wires later on. You might need it since there are a lot of them in the internal system.
Ready your new dual-run capacitor. Using a pair of pliers, pluck each wire and put them onto its corresponding tabs on the new capacitor. Fit them into place tightly; once you’ve placed all the wires, secure your new capacitor into place.
Step #5. Replacing its contactor
A contactor is a mechanical relay that switches high-amperage current to the compressor and condenser fan using low-voltage electricity from the thermostat. They play an essential role in your air conditioning unit, which is why you should change them frequently; otherwise, it could lead to system failure.
Firstly, unscrew the old contactor from its place; you’ll then want to remove its wires and put it in your replacement unit. Then tighten all of the connectors and secure your new contactor in the condensing unit.
Once you’re done, reinstall all the pieces that you’ve removed earlier and test your air conditioning unit right away to check for issues furthermore. If there aren’t any, then you’re good to go.
And that is how to fix an air conditioner fan motor. Again, keep track of your unit from time to time; once you’ve sensed that there’s something wrong, you can base on the steps above. If you couldn’t handle the situation yourself, we recommend that you contact a professional that can help you out. Do you want to read more articles related to air conditioning units?
