They’re a great investment because they take advantage of the heat in the air. The majority of the work is done by an internal fan. The first step is to draw hot air into the system’s innards, where it is transformed into cold air by the coil.

When our air conditioning systems are always running, we often don’t notice that they’ve been overworked. If it occurs, then something is definitely wrong. Because of this, it is imperative that you immediately inspect your appliance if you detect it is not working properly. Fortunately, you’ve found your way here.

If you’re dealing with a similar issue, we’re here to help. We’ll show you ways to protect things from happening in the future; keep reading to find out more.

What is a Fan Motor?

Compressor overheating can be prevented by using the condenser fan motor. Refrigerant flows through condensing coils in your outside unit, and this portion is responsible for cooling it down. Put your palm over the air conditioner while it is operating and you can feel the heat being drawn away from the device. The condenser is to blame for this.

The condenser fan motor, the blower motor, and the compressor motor are all separate motors in your air conditioning system. It’s in the air handler where the blower motor is. Outdoors, you’ll likely need to replace the entire air compressor if the outside compressor motor goes out.

You should replace your fan motor if you see any of these signs:

• Overpriced utility bills
• Temperatures in your home are higher than average
• More time for the air conditioner to chill your house
• The outer unit makes a buzzing sound.

In the event that you detect any of the following symptoms, contact an HVAC repair service firm immediately. Repairing a fan motor as soon as possible may help prevent future harm to your appliance.

What’s the Cost of Repairing or Replacing a Fan Motor?

Between $300 and $500 is the average price of a condenser fan motor (not including installation). There’s a considerably more expensive problem if the compressor fails, which might cost up to $2000.

Your fan motor may be covered by a warranty in some situations. However, it is crucial to know what kind of warranty you have on your air conditioner. For the first five to ten years following installation, a components warranty is likely to cover the expenditures. The majority of component warranties only cover the cost of the part, not the work associated with installing it. If you didn’t register the device and get regular maintenance inspections, several part warranties will be null and void.

Contractors provide labor warranties as a guarantee of their work. This warranty is usually good for a year or so after the installation.

Air conditioner problems might be difficult to pinpoint. That’s why it’s critical to have a professional air conditioner repairman to your home as soon as possible if you discover any problems with it.

Methods That We Can Do To Fix An Air Conditioner Fan Motor

How do you fix a fan motor in an air conditioner? The evaporator coil can freeze and break if the AC unit’s fan doesn’t work, thus it’s critical that your AC unit has one. There’s a good chance you won’t notice it’s progressively breaking down because of overuse. Set a time limit for your use.

As a rule of thumb, if you want your air conditioning unit’s fan to run properly, you should always pay attention to any noises it makes.

If your unit has a manual, you’re good to go. Because it may include useful information, we should spend some time going through some of its sections. If you don’t have a guidebook for your air conditioning machine, you can use this guide as a starting point to learn about its internal workings.

We guarantee that once you’ve dealt with these, you won’t have to deal with anything else. After a hard and exhausting day at work, you deserve a well-earned relaxation. We’ve compiled a list of tools and techniques that will help you get the job done quickly and easily. Because of this, you won’t have a hard time dealing with it in the future.

Step #1. Learning the structure of your air conditioning unit

As previously stated, familiarizing yourself with the external and internal components of your air conditioner will be extremely beneficial if you are a novice in this field. Both the compressor and the evaporator coils are located in the furnace’s plenum and are the most important parts of your air conditioning system.

Here, condensing units are critical. They are responsible for removing heat from the coil by blowing air from the outside onto the coil. If you don’t have it, the evaporator coils may freeze, and your air conditioning system won’t function the same way again.

Step #2. Cleaning the condenser coils

Turning off the electricity to your appliance should always be your first priority. Coils in your air conditioner should not be touched while we clean them since we don’t want anyone hurt. Since condenser coils are typically positioned outside, they are easy to dust off. You’ll want to bring a yard hose along with you now.

Clean your condenser coils by directing the vacuum cleaner toward the higher portion. Verify that the area around the unit is free of any debris by repeating the procedure on the other side.

Step #3. Testing the fuses

Many disconnect blocks have two cartridge fuses. As a result, before beginning any repairs, make sure everything is in order. When a fuse blows, it usually means that a part of the condensing unit is failing. To avoid problems, you should replace nearly all of the pieces.

Set the Ohms scale on a multimeter to the lowest setting and touch the red and black wires of the fuse to each other. Your fuse is in good condition if it displays a numerical value; if not, it is defective.

Step #4. Removing and replacing the run capacitors

First, remove the retaining bracket from the capacitors and let them discharge. Touch the HERM with an insulated screwdriver. Then touch it between the FAN terminal and the C terminals again.

A snapshot of the finished project is a great reference for later reconnections of wires. The internal system contains a large number of them.

The new dual-run capacitor is ready. Pick up each wire and place it on the new capacitor’s tabs with a pair of pliers. Once all the wires have been inserted, fix the new capacitor in place with a screwdriver.

Step #5. Replacing its contactor

Using the thermostat’s low-voltage electricity, a contactor mechanically shifts a high-amperage current from the compressor and condenser fan to the thermostat. You should change them frequently because they serve a critical part in your air conditioning unit, which could lead to system failure if you don’t.

To begin, remove the old contactor from its location by unscrewing it. Next, remove the wires from the contactor and insert them into the replacement. Your new contactor should now be securely attached to the condensing unit.

Check your air conditioning unit right away after you’ve finished installing all the parts you’ve removed previously. No worries if there are none to be found.

Preventing a Fan Motor Breakdown

The condenser fan motor must be maintained annually in order to run at its peak for a long time. If you want your fan motor to last a long time, you should oil it. To ensure that your fan motor is in good working order, contact an HVAC repair firm for regular inspections. A minor repair bill is preferable to a large repair bill when it comes to preventative measures like these.

Professionals can perform thorough inspections of the air conditioning unit during maintenance visits to ensure that everything is functioning as it should. If you notice any flaws, it’s best to solve them as soon as possible so that they don’t become more serious later on. Aside from that, doing these maintenance checks might extend the life of your air conditioner.

If you live in Kansas City and need a new condenser fan motor, give Cates Heating and Cooling a call at 913-888-4470. Your fan motor may be replaced in no time by one of our local skilled experts, so you won’t be without cool air during the summer.
