How to Install RV AC Soft Start

Installing a soft start device for your RV’s air conditioning unit can greatly improve its performance and overall efficiency. A soft start device helps reduce the initial power surge when the AC is turned on, preventing electrical system overload and potential damage. In this guide, we will walk you through the step-by-step process of installing an RV AC soft start.

What is an RV AC Soft Start?

Before we dive into the installation process, let’s understand what an RV AC soft start is and why you need it. A soft start device is an electronic component that helps manage the power load when your AC unit is turned on. It reduces the initial power spike and gradually ramps up the power supply, resulting in smoother operation and reduced strain on the electrical system.

Supplies Needed

Before you begin, gather the following supplies:

  • RV AC soft start kit (make sure it is compatible with your AC unit)
  • Screwdriver
  • Wire cutters/strippers
  • Electrical tape
  • Wire connectors
  • Drill (if necessary)

Step-by-Step Installation Guide

Step 1: Turn Off Power

Before starting any electrical work, make sure to turn off the power supply to your AC unit. This can usually be done at the RV’s main electrical panel or by switching off the AC’s circuit breaker.

Step 2: Locate The Ac Unit’s Capacitor

The AC unit’s capacitor is usually located inside the RV’s control panel or near the AC unit itself. Remove the cover of the control panel or any access panels to locate the capacitor.

Step 3: Disconnect Power Wires

Using a screwdriver, carefully disconnect the power wires connected to the AC unit’s capacitor. Take note of which wires are connected to each terminal to ensure proper reconnection later.

Step 4: Install Soft Start

Follow the instructions provided with your RV AC soft start kit to install the device. Typically, you will need to connect the soft start between the power source and the AC unit’s capacitor. Use wire connectors to secure the connections, ensuring they are tight and well-insulated.

Step 5: Reconnect Power Wires

Reconnect the power wires to the appropriate terminals on the soft start device. Double-check the connections to ensure they are secure and properly tightened.

Step 6: Secure The Soft Start

If necessary, use screws or other securing mechanisms provided with the soft start kit to secure the device in place. Ensure it is properly positioned and well-protected from any potential damage.

Step 7: Test The Installation

Once the soft start device is securely installed, switch on the power supply to the AC unit and test its operation. The AC unit should now start smoothly without any sudden power surge or overload. If everything is functioning properly, proceed to secure any access panels or covers.
