RV life is all about freedom, adventure, and comfortable travel. But there’s one common challenge that can quickly turn a blissful journey into a sweaty ordeal: getting your RV air conditioner to run smoothly without tripping breakers or maxing out your generator. Especially when you’re relying on limited shore power or a smaller portable generator, that initial surge of power (known as inrush current) from your Dometic RV AC can be a real headache.
That’s where a soft start for Dometic RV air conditioner comes into play. These clever devices significantly reduce the power spike when your AC compressor kicks in, making it easier to run your cooling unit on lower amperage sources. Imagine being able to power your 15,000 BTU Dometic AC with a small 2200W generator or even a 20A household outlet – that’s the magic of a soft start. Beyond saving you from inconvenient power trips, they can also extend the life of your AC unit and even reduce its starting noise.
If you’re looking to upgrade your RV’s power management and enjoy a cooler, quieter camping experience, you’ve come to the right place. We’ve compiled a list of the 7 top soft start options perfect for your Dometic RV air conditioner, breaking down what makes each one a great choice.

FAQ Section
Q1: What exactly is a soft start for an RV air conditioner?
A: A soft start device is an electronic module that reduces the sudden surge of electrical current (known as “inrush current”) when your RV’s air conditioner compressor first kicks on. Instead of a hard, instant start, it provides a gradual power ramp-up, drawing significantly less power initially.
Q2: Why do I need a soft start for my Dometic RV air conditioner?
A: Dometic RV air conditioners, especially larger 13,500 BTU or 15,000 BTU units, require a lot of power to start. A soft start is beneficial because it:
* Allows you to run your AC on smaller generators (e.g., 2000W-2200W).
* Prevents circuit breakers from tripping on 20A or 30A shore power.
* Reduces noise and vibration during startup.
* Extends the lifespan of your AC compressor and generator.
* Enables you to run other appliances simultaneously.
Q3: Is a soft start difficult to install on a Dometic RV AC?
A: Most soft start kits are designed for DIY installation, often with detailed instructions, color-coded wires, and sometimes even video guides. While some basic electrical knowledge is helpful, many RV owners find the process manageable, typically involving connecting 3-5 wires inside the AC unit’s control box. If you’re uncomfortable with electrical work, professional installation is always an option.
Q4: Will a soft start reduce the cooling capacity of my Dometic RV air conditioner?
A: No, a soft start only affects the initial startup phase of your AC compressor. Once the compressor is running, the soft start goes into bypass mode, allowing your AC to operate at its full cooling capacity without any impact on performance.
Q5: Can I run two Dometic RV air conditioners on a 30-amp hookup with soft starts?
A: Yes, in most cases! By installing a soft start on each of your Dometic RV air conditioners, you can often run both units simultaneously on a 30-amp shore power connection or even on a single powerful generator. Each soft start reduces the individual AC’s power draw, making it feasible for the combined load to stay within the 30-amp limit.
Q6: Do soft starts work with all Dometic RV air conditioner models?
A: Most soft start kits are widely compatible with various RV AC brands, including Dometic. However, it’s always best to check the product’s compatibility list or description to ensure it supports your specific Dometic model (e.g., specific BTU rating or unit type).
Q7: How much noise reduction can I expect from a soft start?
A: While the primary benefit is power management, many users report a noticeable reduction in the loud “thump” or “clunk” that often accompanies the startup of an RV AC compressor. This translates to a quieter, smoother start, which can significantly improve comfort, especially during nighttime operation.
Q8: Are “learning cycles” necessary for all soft start devices?
A: Some soft start models feature “learning cycles” where they need to start your AC several times to “learn” the specific electrical characteristics of your unit and optimize their performance. Other advanced models may not require these initial cycles and are effective immediately after installation. Check the product description for details on this feature.
