Everything About A Softstart RV

Softstart is an essential feature in any residential ventilation system. It’s part of the control strategy that helps prevent moisture buildup in the home and keeps exhaust air from blowing directly into the house. Instead, it’s routed to a soffit or other open area away from living spaces. There are many different softstart options for residential ventilation systems, each with pros and cons. Here, we’ll dive deep into everything you need to know about softstart RV applications.

1. What Is Softstart?

Softstart is a process that helps you overcome the sudden change from non-production to production mode, allowing for a safe and gradual transition. The term is used in several industries with varying meanings. The manufacturing sector can refer to an alternative to starting up a piece of equipment as usual with a so-called “cold start” or “hot start.” In the RV industry, a softstart can be a system that delays the activation of the ventilation fan or blower until it reaches a specific temperature. This delay is intended to prevent sudden changes in airflow and humidity levels in the living space.

2. How Does The Process Work?

The soft-start process controls the engine speed to keep it under control during such a change. This is achieved by turning off the engine and restarting it after some delay. Additionally, there are several other actions that you need to take before starting up your RV correctly:

• Before turning on your RV, ensure all electrical connections are correctly made and all gas lines are correctly connected at their terminals (for example, at the hose clamps). If this is not done correctly, you may get inaccurate readings and warnings from your onboard or external sensors while trying to start up your RV.
• Make sure that all electrical connections are well seated at their terminals! If they are not entirely seated or have been damaged (for example, pierced by a screwdriver), then you will get incorrect readings from your onboard sensors and warnings from your external sensors.
• Make sure that the electrical connections at their terminals (for example, at the hose clamps) and in the wiring harnesses are well seated! If they are not completely seated in the wiring harnesses, you will get incorrect readings from your onboard sensors and warnings from your external sensors.
• Make sure that all gas lines are properly connected! If they are not correctly connected, you may get inaccurate readings at your onboard or external sensors while trying to start up your RV.

3. Why Softstart Is Used In RVs?

Softstart is essential in all kinds of off-road vehicles that require a lot of power to start up. In case the engine has to be started up very quickly, for example, when a driver is trying to escape from an accident or flood, it is much more likely to fail in this situation. Softstart helps prevent this from happening and makes sure that the engine can be brought up to full speed more slowly, which reduces the risk of damage caused by sudden changes in pressure or temperature. The cooling system of an RV is also compassionate and needs to be cooled down as quickly as possible after a startup. The use of softstart helps ensure that this process takes place as smoothly and safely as possible.

4. What Are The Advantages Of Softstart?

The advantages of using a softstart are as follows.
• It prevents motors from being damaged by reducing the startup voltage. In addition, it prolongs the motor’s life by reducing stress on its bearings or other moving parts. –
• It reduces torque reaction and VFD oscillations. As a result, the motor responds quickly to speed changes without creating torque ripples in the drive train.
• It improves drive reliability and performance by reducing harmonic noise and eliminating vibration caused by high starting torque. And finally, it reduces energy costs as motors use less current during startup. Let’s look at everything about a Softstart RV in detail…

5. What Are The Disadvantages Of Softstart?

The process of softstart works by controlling the engine speed to keep it under control during such a change. This is achieved by turning off the fuel supply and temporarily applying the brakes. This means the engine is not running at full power when switched on, allowing it to cool down more quickly. This process helps prevent the emission of harmful and potentially dangerous gases into the atmosphere during startup.


Softstart is a beneficial technology that allows the engine of an RV to be started up in a more controlled manner. It works by turning off the fuel supply, temporarily applying the brakes, and gradually increasing the engine’s power. This process helps prevent engine or cooling system damage caused by sudden changes in pressure or temperature during startup.
