Review: Critical Missing Instruction for model 450XX with Heat Pump - I installed the Soft Start on a 2024 Coleman Model 45004-0792 that is also a heat pump. Overall, the installation was very straight-forward and the instruction manual was very helpful. There is, however, a critical instruction missing. The manual has you disconnecting and discarding the Start Capacitor & PTCR, together with their red and yellow wires. The problem is that there is also a black wire connected to the Start Capacitor. What the heck do you do with that? There is no mention of it in the instructions. The answer can be found on the yellow schematic on the A/C unit, if you are familiar with how to read a schematic diagram. The schematic shows a black wire from the reversing solenoid going to the yellow terminal block of the Run Capacitor. I'm happy to say that when connected this way, the unit operates correctly - much quieter starting while drawing many fewer amps. A great upgrade for my RV! Review: Super easy install. - I liked that this is a specific soft start made specific for the Coleman Mach air conditioners, not a generic that has more complication. Ours is a 482xx Mach Quiet. Only 4 wires to install and comes with the Mach mounting bracket. The install took about 20-25 minutes max. Works great. We can run the AC off the inverter now if needed. After the fan, then compressor started up it read +/- 1250w ac load from the inverter with just the air conditioner running. Don't forget to put the sealing putty around the wires or you will have to pull the cover back off to install it when you thought your were done! Pro tip: Take some wasp spray up with you. When I pulled the cover, I found 4 wasp nests inside (3 old - 1 new) and had one wasp who kept trying to "help me" with the soft start install! ## Features - REDUCE START-UP AMPERAGE - Extend the life of your Coleman-Mach air conditioner with our new soft start kit that reduces inrush amperage up to 75% and lessens overall power consumption - HOW IT WORKS - Creates a ramped-up power draw at cycle startup for a smooth progression to running voltage thus eliminating troublesome voltage spikes. A short-cycle protection feature increases the overall life of an air conditioner with a Coleman-Mach soft start by lowering startup stress on the compressor. - FEATURES - Unibody enclosure protects unit allowing for optimal performance in a range of weather conditions; No change to exterior aesthetics of AC unit; Easy install from the exterior of your coach - FITS - Coleman-Mach Series 45000, 47000 and 48000 air conditioners - WARRANTY - 2 year limited warranty; Installation will not adversely impact the existing Coleman-Mach warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CF41ZW4W | | Best Sellers Rank | #35,486 in Automotive ( See Top 100 in Automotive ) #103 in RV Heating, Ventilation & Air Conditioning #182 in Industrial Electrical Passive Components | | Brand | Coleman | | Customer Reviews | 4.5 4.5 out of 5 stars (211) | | Date First Available | August 8, 2023 | | Item Weight | 1 pounds | | Item model number | 1497-3601 | | Manufacturer | Coleman-Mach | | Manufacturer Part Number | 1497-3601 | | Model | Coleman-Mach Compressor Soft Start Kit | | OEM Part Number | 1497-3601 | | Product Dimensions | 12 x 6 x 4 inches | ## Images ![Soft Start Kit for All Coleman-Mach Air Conditioners and Heat Pumps - Reduces Start-Up Amperage by 75%, Fits Series 45000/47000/48000, Smooth Ramping for Improved Performance (1497-3601) - Image 1](https://m.media-amazon.com/images/I/51v5vsZD44L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Critical Missing Instruction for model 450XX with Heat Pump *by J***. on January 27, 2025* I installed the Soft Start on a 2024 Coleman Model 45004-0792 that is also a heat pump.

The small generator installed on the Tellaro could not handle the air conditioner surge and would cut off every time. Now the generator handles without a problem. Can't wait for boondocking and tailgating this summer! ## Frequently Bought Together - Coleman-Mach 1497-3601 AC Capacitor Soft Start Control Kit - Coleman-Mach 48204-069 Mach 15 Plus, 15,000 BTU A/C, Black, Wood Skid - Coleman 9233A4551 Heatstrip Assembly --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/550954408-soft-start-kit-for-all-coleman-mach-air-conditioners-heat](https://www.desertcart.hr/products/550954408-soft-start-kit-for-all-coleman-mach-air-conditioners-heat) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-19*
