Coleman-Mach Soft Start Kit for All Coleman-Mach A/Cs & Heat Pumps – 75% Startup Amperage Reduction (45000/47000/48000)

Since 1967, Coleman-Mach has stood for reliable climate control on the move. The Soft Start Kit is designed to address the moment of demand when the air conditioner cycles from idle to running, offering a measured electrical path that can help stabilize on-board power usage in a busy RV lifestyle. Whether parked in a sun-baked campsite or cruising along a scenic highway, this kit aims to support smoother starts and steady comfort inside your coach without altering exterior styling or the core performance of your Coleman-Mach unit.

How it works: at startup, the kit creates a ramped power draw rather than an abrupt surge. This gradual approach helps the compressor transition more gently to running voltage, which many owners report as quieter starting and steadier cooling or heating. A short-cycle protection feature is designed to reduce abrupt restarts, potentially easing stress on the compressor and contributing to more predictable operation over time.

Key benefits

• Reduces startup amperage by up to 75%, lowering the initial power surge drawn by the compressor.
• Creates a smooth ramp to running voltage, helping to avoid voltage spikes and protect electrical systems.
• Short-cycle protection can reduce startup stress on the compressor and extend cycle life potential.

What to expect in use

• Unibody enclosure shields the kit, supporting durable performance across temperature swings and weather conditions.
• Exterior installation keeps the look of your coach unchanged; no exterior modifications are required.
• Fits Coleman-Mach Series 45000, 47000, and 48000 air conditioners, with an exterior installation process.
• Includes a 2-year limited warranty; installation does not affect your existing Coleman-Mach warranty.

Designed for active travelers, this kit offers a practical option for RV owners who want reliable comfort while balancing power awareness. On hot days in crowded parks or while boondocking, a smoother start can contribute to a steadier interior climate and fewer electrical surprises. While results vary with system condition and use, the upgrade presents a potential path toward steadier performance without promising specific outcomes.
