How to Buy a Hard Start Capacitor for RV AC?

Trying to start your RV air conditioner without the right hard start capacitor can be a real pain on a hot day. That's why it's important to do your research and make sure you're getting the best possible product for your needs.

Here are a few things you should consider before making your purchase:

Size:

The first thing you need to consider is the size of the hard start capacitor. If you buy a large one that is not compatible with your RV, you could end up damaging the equipment.

On the other hand,  if you buy a small one, it may not be able to handle the load. Make sure to read the specifications carefully and select the right size for your needs.

Voltage:

The capacitor should also be compatible with the voltage of your RV. Some compressors operate with a low voltage and others with a high voltage. Most of the time this will be 120-240V, but make sure to check before you buy.

Compatibility:

You'll want to make sure that the hard start capacitor you choose is compatible with your RV air conditioner. The last thing you want is for it to be too big or too small, or for it not to fit your unit properly.

HP:

The horsepower of the air conditioner also needs to be considered. Not all capacitors are made to work with all air conditioners, so make sure to check before you buy.

Ease of Installation:

The last thing you want is a hard start capacitor that's difficult to install. Make sure you choose a model that's easy to set up and doesn't require any special tools or expertise.

Brand:

Not all brands are created equal, and not all hard start capacitors are made the same. Make sure to do your research and find a reputable brand that you can trust.

Price:

Finally, think about your budget and what you can afford. There is a wide range of hard start capacitors available on the market, so you're sure to find one that fits your needs and your wallet.

How to Install a Hard Start Kit?

A hard start kit is an electrical device that is used to help motors start more easily. Installing a hard start kit is a pretty easy process, but it's important that you take your time and follow the instructions carefully.

Here are the steps you need to take to install a hard start kit:

1. Locate the hard start kit. The kit will be either in the motor's original packaging or in a separate box.

2. Remove the old capacitor. The capacitor will be located near the motor and will have two leads coming out of it. Disconnect the leads and set the capacitor aside.

3. Install the new capacitor. The new capacitor will have two connectors on it. Reconnect the leads to the capacitor and tighten the screws.

4. Test the capacitor. Turn on the RV and start the AC motor. The capacitor should start humming immediately. If it doesn't, turn off the RV and check the connections.

5. Replace the cover. Replace the cover on the capacitor and tighten the screws.

6. Connect the wires. Connect the black wire to the negative terminal and the white wire to the positive terminal.

7. Secure the wires. Use electrical tape or a wire nut to secure the wires.

8. Repeat on the other side. Repeat the process on the other side of the RV.

Once you have installed the hard start kit, test it out by starting the AC motor. If it starts up without any problems, you're good to go!

FAQs:

There are a few frequently asked questions when it comes to hard start capacitors. Here are the most common questions and answers.

01. How Do You Size a Hard Start Capacitor?

When sizing a hard start capacitor, you need to find the running current of the AC motor. This is usually listed on the motor's dataplate. Once you have this information, you can choose a capacitor with a capacity that is equal to or greater than the running current.

02. When Should You Use a Hard Start Capacitor?

You should use a hard start capacitor when the RV AC motor doesn't have enough torque to start quickly. This usually happens when the weather is hot and the AC unit is running continuously. If the RV manufacturers installed a hard start capacitor, then it is not necessary to add an additional one.

03. Can RV Air Conditioner Run Continuously?

Yes, an RV air conditioner can run continuously without damaging the compressor. However, using a hard start capacitor will help the AC motor run more effortlessly. When the weather is very hot, this can make a big difference in your comfort level.

04. Where is the AC Capacitor Located?

The AC capacitor is located on the outside of the RV near the AC unit. It is typically a cylindrical object with two wires coming out of it.

05. Can Hard Start Kit Damage Compressor?

A hard start kit will not damage the compressor. Sometimes it can overheat the compressor, lead to compressor failure, or increase the running current. However, these are rare occurrences and typically only happen when the hard start kit is oversized.

06. How Many Watts RV Air Conditioner?

Most RV air conditioners have a power rating of around 1500 watts allowing them to operate on a smaller generator. However, there are some units that are as high as 3000 watts. The high inverter generator is the best choice to power the RV air conditioner.

06. How Many Watts RV Air Conditioner?

This will vary depending on the size and type of AC unit. Most RV air conditioners have a rating of between 1900 to 3500 watts to startup. It uses between 600 to 1700 watts to run.

07. What is a Hard Start Kit for RV AC?

A hard start kit is an electrical device that helps an AC motor start more quickly. It is typically used when the weather is hot and the AC unit is running continuously.

08. What Happens if You Oversize a Capacitor?

If you oversize a capacitor, it can raise energy costs. It is important to choose a capacitor that is equal to or greater than the running current of the AC motor.

09. What's the Difference between the Micro Air Start and a Hard Start Capacitor?

The micro air start is a small, lightweight device that is connected directly to the compressor motor. It is perfect for use on small AC motors. A hard start capacitor is a heavier, more durable device that requires installation. It is typically used on larger AC motors.

Conclusion:

Installing a hard start capacitor is a great way to help your RV AC motor run more efficiently. It can be especially helpful in hot weather when the AC unit is running continuously.

When shopping for a hard start capacitor, it's important to keep the above factors in mind. By considering the capacitor's capacity, voltage, temperature rating, and connection type, you can choose the best hard start capacitor for rv ac.
