Advent Air Accessories and Parts - ACMSCKIT

  • RV Air Conditioners
  • Start Capacitor
  • Advent Air

If your generator or shore power needs a little extra help to start your RV AC unit, this start capacitor will give it the power boost it needs. Relay switch turns the capacitor off once power has been supplied.


Features:

  • Start capacitor jumpstarts the AC (sold separately) when a campsite or generator doesn't provide enough power
    • Stores energy that will later be used for the next startup
  • Relay switch turns starts capacitor off once sufficient power has been supplied
  • Easy, bolt-on installation with the included hardware


Specs:

  • Overall dimensions: dimensions: 2-1/8" long x 3-5/8" deep x 6-5/16" tall
  • 1-Year warranty


How the Start Capacitor Works

If your campsite or generator isn't able to draw the power you need, then you may have difficulty starting your AC unit. The included start capacitor, however, can eliminate this problem. The capacitor stores energy that will later be used to jumpstart the AC. Once the sufficient amount of power has been supplied to the AC, the compressor will start to run, and the internal relay switch will turn the start capacitor off. At the same time, the compressor will send "back voltage" to the relay switch and capacitor in order to energize them for the next startup.


Simple Installation

To install, bolt it to the fan motor support with the included hardware and then route the wires to the run capacitor.

my order left etrailer within an hour of being placed. it arrived freight free 3 days later via ups. the ac was packaged very well and arrived without any visible damage. it is compatible with original thermostat and ceiling control box from a 2003 dometic 15000 btu duo therm . had to make a minor adjustment to the partition between the air chambers.the original ceiling plate was reusable as well.



by:

This was an easy installation, thanks to the etrailer vidio.



by:

It only makes sense to install this extra capacitor to your RV air conditioner. This unit arrived with easy to follow printed instructions and the video instructions were a great help. Installation only took a few minutes.
***One tip I would offer when attaching the capacitor to the blower - screw in the attachement screws first without the capacitor. The screws are a tight fit intially and this step will allow them to go in much easier when you are attaching the capacitor body.

As always etrailer has the right products at the right price with excellent customer service.

Still working strong. Helps start AC with our generator.

Great no Problems!!



by:

Start Capacitor works as it should.



by:

Our AC starts good on 20 amp circuit using this start capacitor



by:

Very fast delivery time. Excellent packaging to help prevent damage during shipment. Haven't installed parts yet but everything looks good.



by:

Installation went well and the instructions was easy to read and understand.I had the old unit out ,cleansed the roof and installed the new unit by myself in half a day and finished up wiring inside in a short time .Everything worked as explained,Thanks so much for your input and help with picking the right replacement ac unit



by:

The item was delivered on time and very very easy to install I had it done and I would say less than 5 minutes between removing the cover routing the wires over to the capacitor and making the connection everything that was needed was included would recommend buying. I'm using a 3500 run time generator at my camper to operate a 15,000 BTU air conditioner and I wanted every Edge to help the compressor start without bogging down the generator I haven't done the actual run yet but I'm sure it will be okay and do as it was meant to do I've noticed Improvement with the startup of the air conditioner even under normal conditions plugged into Shoreline.



by:

Very easy to install. The included instructions were very helpful.



by:

This is a must have for using the advent air 15kBTU with a generator. Great product, very easy installation, very easy wiring.



by:

Not sure if I needed it, but I added it with my new ac because the old one had one. It was the simplest install. You may as well do it and not worry about hard starts.



by:

One of those things. You can't really tell if it's working. Was a quick and easy install though. Instructions were quite clear.



by:

Exactly as advertised, installed myself. If you aren't doing business with etrailer, you get what you deserve.



by:

Installed this start capacitor on my new Advent RV air conditioner that replaced an old Carrier Air V unit that I had installed a soft start on. This start capacitor was only $19 dollars compared to $300 for the Soft start.



by:

I am writing this due to the all the emails etrailer sends to me to remember to review the item… This review is more for etrailer than the product as I haven’t been able to install the item yet. I ordered this because the website said it would be delivered on July 14th, which would have been perfect timing for our trip. I was planning on installing it that afternoon, so we could take off that evening. However, it didn’t ship until the 14th, so I wasn’t able to install it before we left. The AC compressor struggled to start and even tripped the breaker a few times. Luckily, we were in camp when it happened, and not away so I could reset the breaker.

I know it might not be couth to write a review without actually using the item, but I also paid for a service. A service which etrailer fell short.



by:

Very friendly support. Helped with picking right unit for our needs. Quick delivery and arrived undamaged.



by:

Easy to install and works great.



by:

Great unit, no problems since new



by:

Great service



by:

great service.was able to answer all questions and was delivered on time.



by:

Love the Advent. Easy installation and works as advertised.Keeps the trailer that i race karts out of very comfortable.Installed also the heat strip and it does well also when needed.



by:

Installed on Advent air conditioner replacement for a Dometic unit. Easy installation. Works fine.



by:

I just now was able to install. Installation was easy and the start capacitor works as it should.



by:

I don't notice a difference in the performance at start up. Maybe I didn't need this part afterall. It comes on initially but it wont turn back on after i turn the unit off. It didn't come with the mounting screws so I got some from the hardware store. The videos online are wa
Hy I gave it 4 stars and I trust it will serve me well in the future. Don't know we will see.

  • Will A 2,500 Watt Champion Generator Be Enough To Power An Advent Air RV Air Conditioner System
    The start capacitor # ACMSCKIT included with the Advent Air # ACM135C will drop the starting wattage down to approximately 1,800 watts with a 1,450 running wattage so your Champion generator # CH34FR with 2,500w surge rating and 1,850w running wattage will be enough to handle the demand. If you plan on powering more items in your trailer then you can use the Parallel Kit # CH74FR and another # CH34FR to double your available wattage.

    I've attached a video below where Dave will walk you through the installation of the Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT on your Advent Air RV Air Conditioner w/ Air Distribution Box and Start Capacitor - 15,000 Btu - White # ACM150C. At the 1:30 minute mark he'll attach the black wire that has the single connector to the HERM Circuit and the other black wire with the second spade connector coming off of it to the common circuit.

  • Is a Start Capacitor Required to Use the Advent Air RV 13,500 Btu A/C
    No, the Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT is not required to use the Advent Air RV Air Conditioner # ACM135. The Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT will help to jumpstart your A/C if you are not getting enough power to start your A/C. It stores energy that will later be used for the next startup. It is not required to have the start capacitor, but it is a good tool to have.

  • Recommended Replacement for Airxcel model 48253C969
    The Airxcel model 48253C969 that you identify is the same as a Coleman Mach AC unit rated for 13,500 Btu. The Advent Air RV Air Conditioner, # ACM135B that you linked to is a 13,500 Btu and designed to be a cost effective direct replacement for the Coleman AC units. It will install using the Coleman Mach Adapter Wiring Kit for Advent Air RV Air Conditioners, # ACCOLKIT. If you want to add the start capacitor that stores energy to be used later to help jumpstart the unit for the next startup,...

  • Replacement AC For Trailer Trailer With Existing Advent AC
    When it comes to replacing your Advent AC unit on your trailer I recommend The Advent Air RV Air Conditioner - 13,500 Btu - Black # ACM135B.This system will replace, upgrade, or add an additional air conditioner to your trailer. This system is compatible with both a ductless or ducted system. This AC can be paired with a Coleman Mach using the wiring adapter # ACCOLKIT which is sold separately. This system has a bolt-on installation, and has a black, hard plastic cover that protects the...

  • What Is The Smallest AC Unit For Adding AC System To A Cargo Trailer/Camper
    Hello Tyson. The smallest AC unit we offer is the Advent Air Low Profile RV Air Conditioner and this will be a great option for you. Since this is a smaller trailer you can definitely get away with a 13,500 BTU unit. These AC units require the roof to be between 2-1/2" and 5" thick, so please do keep that in mind during your build. For a complete AC system I recommend the following: - Advent Air Low Profile RV Air Conditioner - 13,500 Btu - White # ADV79FR - Air Distribution Box w/ Built-In...

  • Is There A Heat Strip Available For An Advent Air RV Air Conditioner System
    Yes, you're looking for the Advent Air Heat Strip # ACMHD to go along with your # ACM150. This system requires a 14-1/4" long x 14-1/4" wide roof opening, which is pretty typical for all RV air conditioner systems. I highly recommend getting the start capacitor # ACMSCKIT as well to cut down on the power surge every time your unit starts up.

  • Replacement For Dometic 59136.621 Air Conditioner With Heat Pump
    There is indeed a good option to replace your current Dometic 59136.621 air conditioner, which is a 15,000 Btu AC. The best option is one from Advent Air: - Advent Air RV Air Conditioner for Dometic Setup w/ Start Capacitor - Black # ACDOM150B or White # ACDOM150 This is also a 15,000 Btu air conditioner, and it comes with a start capacitor to help boost the power to ensure your AC gets up and running when you need.

  • Replacing a Carrier A/C Unit with an Advent Air A/C Unit
    The Advent Air Rooftop RV Air Conditioner part # ACM135 for 13,500 Btu's or part # ACM150 for 15,000 Btu's are both available and ready for purchase. The Coleman Adapter Kit part # ACCOLKIT that you referenced is for Coleman units so it will not be needed to replace your Carrier. However, both of the above kits come with everything that is needed anyhow. The adapter kit is more or less to retain your wall thermostat which you said you do not have. There are no Advent to Carrier adapter...

  • Compatibility of Solar Panel System for Off-Grid Living
    You can live and run your AC even off a solar power system if you have a large enough battery backup system, but I also recommend having a generator on hand. The Go Power Solar AE-4 All Electric System with MPPT Solar Controller - 760 Watt Solar Panels # 342-75010 is a great option for going off-grid. The battery bank you need will be dependent on your power needs. AC does have a significant startup and draw on power, so I definitely recommend having a capacitor on your AC to assist...

  • AC With Heat Strip For Enclosed 14 By 7 Foot Trailer
    The Advent Air RV Air Conditioner - 13,500 Btu - White # ACM135 can be installed on a trailer and happens all the time. The issue is with the roof of the trailer and making sure if can support the weight of the AC unit and then you will need to route and supply power to the AC. So make sure you build up the roof and add supports to it if needed. This AC unit weighs in at 80 pounds. It also needs a little help to start if you are using a smaller generator so you can get the Start Capacitor...

    Hello Tim. We can definitely set you up with a complete AC system with an Advent low profile unit. We currently do not offer these parts as a package, but you can purchase all of the exact same components separately. To answer your question, yes, the same air handler will work with the low-profile unit.

  • Recommended Ductless Air Conditioner to Replace Fan
    We can get your Keystone Montana set up with an added air conditioner to replace your current fan. I really like the Furrion Chill systems as they tend to be quieter than others, and gives you really nice cooling via its air distribution box that has the controls directly on it. For a smaller AC, like you mentioned, there is a 13,500 Btu unit that will be perfect, and is the following part number: - Furrion Chill HE RV Air Conditioner System # FR52PR

  • Recommended SoftStartRV Kit for a 2022 Forest River Rockwood Geo Pro
    The Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT is specifically for Advent ACs and is not going to work with your Advent AC - you'd need to use the SoftStartRV Soft Start for Single Zone Air Conditioner Setup # SSR54FR which is a universal kit.

  • Replacement For Dometic Duo-Therm Quick Cool RV Air Conditioner
    Hello Cherry. To replace your Dometic Duo-Therm Quick Cool AC Unit I recommend the Advent Air # ACM150. This is made to be directly compatible with your existing Dometic AC system. You'll just need to remove the cover to your air distribution box so that you can get to the mounting bolts and wiring. Aside from you can basically just swap out the rooftop portion and leave the rest of the AC system as-is. I do suggest that you pick up a Start Capacitor # ACMSCKIT. You also have the option...

  • Will Advent Air Replace Dometic DuoTherm Brisk II AC Unit
    The Advent Air Rooftop RV Air Conditioner # ACM135 has connectors that match up with Dometic AC unit wiring. Since your DuoTherm Brisk II is a Dometic AC unit the Advent 13.5K will install directly in its place and you can use the same controls. I do recommend also installing the Start Capacitor # ACMSCKIT as well. This stores energy needed to start the Advent unit so that you aren't pulling a lot of power just to start your AC unit.

    The SoftStartRV Soft Start for RV AC Units # SSR54FR is designed to work with single-phase air conditioner units. If you remove the shroud there's a tag on the compressor that should state if your unit is single-phase or three-phase. If you have an Advent Air unit then you'll want the Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT instead. If you were replacing the start capacitor on a Furrion unit you would want the # FR45FR for a 14,500 BTU unit and the # FR65FR for...

Please note, it also does not come with a distribution box but you can also add one easily using the Air Distribution Box for Advent Air RV Air Conditioners part # ACDB.

If you would like an electric heat pump the # ACMHD can be added on.

  • Best & Most Efficient Replacement For Carrier Air Conditioner
    We can absolutely get you set up with a replacement for your Carrier air conditioner, and the best, most efficient option is from Advent. I highly recommend going with the 15,000 Btu unit for the most cooling power, and you may not even need a new distribution box if your Carrier's is working fine. I say "may" because the adapter needed that makes the AC compatible with your Carrier's air distribution box is not compatible with Carrier units that have a heat pump. To make it simple, I'll...
