Read on to get the scoop on soft starts and the RV air conditioner!
Quick Summary of Key Points
A soft start for an RV air conditioner is a device that controls the electrical current when starting and running the AC unit. It limits the initial startup amps and extends the life of the compressor by gradually increasing the amps as it warms up, reducing strain on the motor.
What is a Soft Start Device for an RV A/C?
A soft start device is a specialized electronic component that helps protect an air conditioning system by providing a gentle, year-round approach to starting up the compressor. This prevents strain on the compressor motor and keeps electrical damage from happening when your RV A/C starts up during the hot summer months or after winter storage. They offer the advantage of longer life, better control over cooling cycles and greater energy efficiency for any type of compressor application.
The debate about soft start devices centers around their added complexity and cost, as well as the potential for failure when separated from other components. Proponents of installing soft start devices point out that although these components are more expensive than regular starters, they can make up for it in energy savings throughout their lifespan, as well as provide extra protection for your RV’s A/C compressor motor. Opponents argue that most RV owners do not need a complex component like this and it isn’t worth the extra cost.
Ultimately, whether or not you decide to install a soft start device is up to you. This will depend on factors such as how often you plan to use your RV and how long you want your air conditioner system to last.
Now that you know what a soft start device is, let’s take a closer look at how they work in the next section.

How Does a Soft Start Device Work?
Soft start devices are electronic components that reduce the high inrush current that AC compressors require to get started. In a traditional RV air conditioner, all of the required power is sent directly to the motor when it is switched on, resulting in a large draw of electricity. With a soft start device in place, the current is instead limited and slowly ramped up over time, allowing the compressor motor to function without drawing as much power suddenly. This reduces the electrical load and associated strain on the AC unit.
On the one hand, soft start devices provide considerable benefits to RV air conditioners. The reduced inrush current allows for more efficient operation, which can help extend the life of the system and protect against surging or “brownouts” due to sudden large draws of electricity that some power sources may not be able to support. Soft start devices also reduce noise associated with starting current spikes and eliminate any potential damage or tripping of circuit breakers that those spikes can cause.
On the other hand, soft start devices introduce their own set of possible issues such as their own failures or incorrect wiring. Without power going directly to the motor upon startup, an AC unit with a soft start device may take longer to cool room temperatures than traditional systems. Additionally, some RV owners have reported having further issues such as compressor motors failing after replacement soft starts were incorrectly installed due to short-cycling or insufficient cooling capacity caused by a lack of direct power during startup.
Overall, however, soft start devices offer numerous advantages that make them worth considering when installing an RV air conditioner. For example, they often save energy compared to standard units and provide greater protection from surges or circuit breaker trips due to high starting amps. As long as they are installed correctly and compatible with the RV’s specifications, they can provide improved performance compared to their traditional counterparts.
To understand better how reducing starting amps improves performance of an RV air conditioner equipped with a soft start device, it is necessary to investigate further in the following section.
Reduces Starting Amps
A soft start significantly reduces starting amps during the initial run of an RV air conditioner. When the compressor and fan motors turn on, they draw a large surge of current that can become costly over time and tax electric systems. By reducing the amount of current draw, soft starts help lower the wear and tear on electrical components, extend the longevity of both components, as well as potentially reduce utility costs. However, some argue that running at maximum amperage for a brief period of time will not cause any real harm to the electrical system, so a soft start may not be necessary.
Still, others recognize that the primary benefit of a soft start is to protect against unexpected power outages and surcharges that could occur when both motors are running full force. While this argument could be disputed in cases with more robust electrical systems, it is essential that RV owners understand how much protection a soft start offers them and why it’s important when considering all facets of their air conditioning system.
Leading into the next section: Knowing how a soft start reduces starting amps is just one part of understanding its overall benefits; next we’ll explore how it delays fan motor start-up time.
- A soft-start kit works by providing a gradual start-up for the electrical motor in the RV’s air conditioner, limiting the initial current spike.
- Soft starters can reduce the amount of energy consumed by RV air conditioners when starting from 35%-50%.
- Studies have shown that replacing a traditional starter switch with a 3 phase soft starter in an RV air conditioner can extend its service life by up to 50%.
Delays Fan Motor Start
Delays Fan Motor Start is an important component of Soft Start. It helps protect the RV air conditioner and improve its longevity. By delaying the start of the fan motor, the RV air conditioner can prevent any sudden electric overload that could be caused by having the fan motor turn on all at once. This gradual start-up process also allows for a shorter operation time as well as reduced power consumption.
Defenders of Delays Fan Motor Start attribute it to reducing wear and tear on the fan motor from frequent starts and stops by spreading out the load instead of rapidly expecting a full load from the fan motor. This extends not only the life of the fan motor but also has the potential to save money in repair or replacement costs over time. They also tout its ability to reduce wattage by 1/3 or more since it spreads out the load of electricity use.
While there are advantages to delaying fan motor start, there are also criticism on this type of soft start feature. Detractors posit that delays fan motor start can lead to inconsistent cooling power and decreased performance as a result due to the slow ramp-up process. In addition, they argue that while cost savings on electricity may be realized, it may come at a higher initial cost since adding these types of features carries an additional price tag depending on the brand, model and specifications.
In conclusion, delays fan motor start can help improve RV air conditioner longevity by avoiding sudden spikes in electricity usage when initiating a full load from the fan and helps spread out electricity usage for greater efficiency and cost savings over time. However, there are critics who suggest that this eventual cost savings may be offset by higher initial costs with this feature included, as well as inconsistent cooling performance. The next section will further explore how Soft Start provides thermal protection with its advanced capabilities designed to avoid costly issues and breakdowns common with RV air conditioners.
Provides Thermal Protection
Soft start technology provides thermal protection for RV air conditioners. When the compressor starts up, it requires more current than when it is running, which places a high demand on the motor and can lead to problems like hot spots in the windings, over-heating, increased bearing wear and shortened motor life. Thermal protection is a safety feature that enables a slow start to reduce the demand placed on an air conditioner’s motor, thus providing protection against these issues. During the starting process, a soft start device ramps up the voltage over time so the electricity used is spread out over a longer period of time. This works to lower inrush current levels to improve motor performance.
The addition of thermal protection via a soft start also provides improved reliability since it reduces some of the major causes of failure in an air conditioner’s compressor motor. Furthermore, this type of protection helps extend its life expectancy by reducing component wear and tear that would occur during the starting process without thermal protection.
On the other hand, adding thermal protection with a soft start increases component cost and complexity, as well as adding additional installation time – all resulting in more expensive repairs or replacements. Depending on usage patterns and conditions, there may be instances where thermal protection isn’t absolutely necessary; however it’s ultimately wise to invest in this feature for optimal performance of your RV air conditioner.
In summary, soft start technology provides thermal protection for RV air conditioners by slowly ramping up voltage to limit inrush current. This helps protect against issues such as hot spots, over-heating, increased bearing wear and shortened motor life – while extending their life expectation and improving their reliability. While there are additional costs associated with installing a soft start device, having thermal protection installed can be beneficial for long-term air conditioner performance.
Next we will discuss different types of soft start devices available for RV air conditioners.
Types of Soft Start Devices
When it comes to soft start devices, there are two major types; integrated and external. Soft start RV air conditioner units that come with an integrated soft start device have a built-in electrical device that helps the compressor motor reach its running speed gradually – reducing the amount of power it needs when starting up.
External soft start devices, on the other hand, are separate pieces of hardware that regulate energy flow whenever the RV AC is turned on. They work by reducing the electrical current that is sent to the compressor motor, resulting in slower acceleration and reduced power draw at startup.
The debate surrounding these two kinds of soft start devices centers on how efficiently they help reduce power during startup. While some argue that integrated soft starts are much more efficient because they provide immediate protection as soon as the RV AC unit is switched on, others prefer an external soft start as they are easily adjustable if needed and can be moved from one machine to another if necessary. Ultimately it is up to you to decide which type of soft start will best suit your RV air conditioning needs .
While both types of soft starts are effective at reducing electricity consumption when starting up your RV AC unit, there are benefits and downsides to each approach. Taking into consideration the pros and cons of each type, you can make an informed decision about which device will work best for you and your vehicle.
To conclude this section, using either an integrated or external soft start device for your RV air conditioner will result in lower power consumption when switching the unit on, offering cost savings in addition to environmental advantages. Now let’s take a look at some of the benefits that a soft start device offers when used with an RV A/C system.

Benefits of a Soft Start Device on an RV A/C
Soft start devices are a relatively new addition to the RV air conditioning world and have been designed to improve the performance of your A/C unit. They reduce the airflow coming from the compressor, reduce noise and eliminate in-rush current during startup.
The main benefit of adding a soft start device to your RV air conditioner is that it helps reduce wear and tear on the unit. By limiting the power surge when starting up, the compressor won’t be subjected to as much stress and can therefore last longer than it would without a soft start device installed. The reduced noise level is also hugely beneficial, especially when camping in close proximity to other campers or in a quiet area.
Another advantage of installing soft start devices on RV air conditioners is easier maintenance. By reducing the amount of electrical load put on the system during startup, maintenance tasks can be completed quicker and with less strain on any technician involved.
In some cases, however, soft start devices may not be necessary or may even hinder performance. Firstly, they add size and weight to an RV A/C unit which can be prohibitive for smaller RVs. Secondly, they can add extra costs to owning an RV since they need to be installed by professionals and may require extra wiring if your unit does not support direct mounting. Finally, these devices may limit total cooling capacity when combined with certain sizes of A/C units.
For most motorhomes and trailers though, a soft start device can provide additional protection for an RV’s A/C system while providing more consistent cooling performance and quieter operation. Installing a soft start device on an RV A/C will therefore act as a shield against power surges and help extend its life expectancy.
Having discussed the benefits of soft start devices for an RV air conditioner, next we will look at how you can install one yourself on your own RV A/C unit.
Installing a Soft Start Device on Your RV A/C
Installing a soft start device on your RV air conditioner can be a beneficial upgrade, as it allows for easier starting of the motor and works to reduce the initial stress on the compressor, helping to increase the life of your air conditioner. Depending on the age and model of your RV air conditioner, the installation process may be a simple task or may require more advanced skills.
The installation process requires disconnecting power to the RV air conditioner, then mounting the soft start device onto an open frame near the relay contacts. Once mounted, connect the 3-wire leads from the device to the capacitor/Relay assembly. Finally, reestablish power, test for proper operation of the AC system, and perform final calibration if applicable.
Before attempting to install a soft start device on your own, weigh the benefits against potential drawbacks such as cost and complexity. Although adding a soft start device is not overly complicated or expensive, in some cases it could be an unnecessary addition or even potentially disrupt power distribution to other components in your RV if installed incorrectly. Additionally, newer-model air conditioners might not need a soft start device at all since some models already come with this option pre-installed. Ultimately it’s important to assess whether or not you are qualified to undertake this project yourself before making any attempts.

Are there any negative impacts from using a soft start for an RV air conditioner?
Yes, there are some negative impacts from using a soft start for an RV air conditioner. While a soft start does help to alleviate some of the stress on the power supply and reduce the amount of voltage spikes which can cause damage to other electrical components, it also shortens the lifespan of the AC unit. Additionally, while a soft starter may initially save energy costs, it will eventually cause one to spend more in repairs and maintenance due to the increased wear and tear on the components caused by the soft start system. As with any type of motor and motor control, it is important to consider the full cost implications when considering whether or not to invest in a soft start system.
What other systems benefit from a soft start for an RV air conditioner?
A soft start for an RV air conditioner is beneficial not only to the air conditioner itself, but also to other RV systems. By slowly ramping up the current used by the air conditioner, it prevents spikes in current draw that could potentially damage the RV’s electrical system and blow fuses. Additionally, a softer start reduces any shock that could be caused from sudden stops and starts of heavy diesel or gasoline engines, which can lead to reduced life of engine components. Since cooling accounts for about 30% of overall energy used in an RV, a soft start can also help save fuel usage. This can result in better fuel efficiency, improved battery life, and a quieter ride for occupants.
What are the benefits of having a soft start for an RV air conditioner?
The benefits of having a soft start for an RV air conditioner are substantial. Soft starts allow for more efficient use of energy and help to reduce the wear and tear on your air conditioning unit. With a soft start, your AC can maintain a consistent temperature without having to cycle on and off so much, resulting in longer service life and lower energy bills. The soft start also helps to reduce sudden spikes in current draw when the AC starts up, which helps prevent additional strain on your electrical system or generator. Finally, increased comfort levels are possible since the AC will not make those jarring stops and starts associated with cycling on and off. Overall, having a soft start is an invaluable addition to any RV’s air conditioning system and is worth every penny.
How does a soft start for an RV air conditioner work?
A soft start for an RV air conditioner works by initially starting up the system in a low power mode to reduce stress on the electrical components. This is beneficial as it minimizes wear and tear, limits current draw, and prevents any shutdowns due to an overload. When a soft start unit is used, the compressor gradually ramps up the power, which in turn helps keep the temperature more consistent by providing a steady flow of cool air. The ramp-up time also ensures that the compressor’s current is maintained at a set level and doesn’t spike or dip suddenly. This helps prolong the life of the compressor and avoid any potential problems with electrical overloading caused by surges or drops in amperage.
How can I install a soft start for an RV air conditioner?
Installing a soft start for an RV air conditioner is relatively straightforward and can be done with a few tools. First, you will need to purchase the correct soft start device for your RV air conditioner. Once you have it in hand, turn off the main power to your RV and disconnect any wiring from the AC unit. Then, following the instructions that come with your soft starter, connect the incoming hot wire from the AC to one of the terminals of the soft starter. After that, run a wire from the other terminal of the soft starter to the line side of your circuit breaker. Finally, using an appropriate size fuse or contactor, reconnect the power lines to your AC unit. Allow plenty of time for any capacitors and/or motor windings to charge up before turning it on.
That’s all there is to it – your soft starter will now regulate the start-up current of your RV air conditioner when you turn it on, reducing strain on its motor and extending its lifespan.
