Want to Solve your Dometic & Norcold Reliability and Safety Issues?

The Fridge Defend is an automatic controller that limits your Dometic or Norcold RV refrigerator boiler temperature.


Both Dometic and Norcold RV refrigerators are fine products. But, as you must know, there have been many recall campaigns due to fire issues. Even if your fridge has not been recalled, let's say it is a newer fridge, your fridge has one of these so called safety recalls on it from the factory.

The Fridge Defend solves the root-cause for the failure of these otherwise great refrigerators. The root-cause of RV fridge failure that leads to fires is the overheating of the boiler. The recalls do not, and can not address the root-cause of failure because the Fridge Defend is patented.


By clicking this link you will learn that by limiting the boiler temperature of your Dometic or Norcold RV fridge, the fridge life is increased while helping to prevent RV fires. This all saves you money and valuable vacation time, while giving you added life and property protection.

Being a retired fire chief, I know the value of fire prevention and also know firsthand the destruction, loss of life, pain, and agony that can go along with accidental and unwanted fire. So I strongly endorse the Fridge Defend by ARP for anyone who has an absorption RV refrigerator.
Mike Burger, Kochville Fire Chief (Ret.)
I am very happy with the Fridge defend and the support Paul & Mao provide.
The ARP improves safety and reliability, and that’s a great gadget!
Mark Nemeth, Escapees RV Club Technical Advisor
Last summer we had a series of flat tires on our 5th wheel. We never worried about our fridge when the trailer was not level on the side of the road. The Fridge Defend protected the fridge from overheating damage, which shortens the life of the fridge. Bob Livingston RV/MH Hall of Fame & Editor Trailor Life Magazine
To me the ARP Controller is a requirement.
I would not operate a Dometic or Norcold RV fridge without the protection the Fridge Defend offers. Brett Wolfe

The Fridge Defender is the best aftermarket item sold today, it is truly a value for anyone with a Dometic or Norcold fridge. You will sleep better knowing such a quality product is helping protect your cooling unit and your safety. Phillip Enoch, RV Inspector & Technician
While in OH, we attended an RV Rally. As usual we leveled our RV, but the leverlers sank into the graound. The Fridge Defend prevented our referigerator from overheating due to being off-level. Thanks Paul & Mao for a great product! JVAndrews, Retired Aeronautical Engineer - USAF

Fridge Doctor Saves


The Fridge Defend monitors the vital signs of your fridge and solves problems before they happen. Your RV Refrigerator boiler operates at about 350 degrees all the time, but even a brief time off-level, like driving up or down a hill , can send that temperature sky-rocketing. Events like this produced a lot of thermal stress in the fridge boiler, stress that causes the metal to fatigue and the anti-corrosion chemicals in the coolant to deteriorate leading to premature fridge failure and perhaps even causing a total fridge meltdown.

The Fridge Defend by ARP can monitor the boiler temperature and automatically shut down the boiler if temperatures begin to climb out of normal range. Best of all, the Fridge Defend by ARP continues to monitor and re-starts the fridge once it cools down again, so that your food doesn't spoil. And all without any effort by you!

Fridge Failure Ahead

We have all heard about the series of recalls for Dometic and Norcold RV refrigerators. These recalls attempt to address premature refrigerator failure and catastrophic rupture type failures. As a frustrated consumer, the inventor of the patented Fridge Defend by ARP found what made these once reliable refrigerators vulnerable to damage, both long term and immediate. The source of many of these issues is a lack of active temperature management of the cooling unit which allows it to overheat on a regular basis, causing slow but cumulative damage that can result in a no cooling situation which may have otherwise been avoided.


The Fridge Defend by ARP addresses these problems with a more sophisticated management technique that controls the cooling unit better, plus it has the major advantage that it will automatically re-start the fridge cooling unit after a high temperature cut-off. This avoids the loss of the food kept in the fridge.

ARP Control Norcold Dometic Fridge


The ARP Control has been designed to be simple on the outside making it easy for Dometic and Norcold installation.

The drawing to the right shows how easy it is to install, just provide power, run one wire to your fridge control, and install the temperature sensor.

Fridge Defend Takes High Road


The Dometic and Norcold controls do a great job for what they are designed to do. These factory controls keep the inside of your fridge cold, but do not keep the refrigerator heating system from overheating the cooling unit. Because the Fridge Defend by ARP is designed by a controls system engineer, the inside of the ARP has a smart control scheme. Smart means that you enjoy your adventure and the Fridge Defend keeps your fridge running safe. This smart method senses overheating situations and automatically turns off the heaters, then restarts the fridge when it is safe, usually before the inside of your fridge can warm at all.


The answer to the above questions is easy, when industry sees the benefits of the patented product, then attempts to patent it for them self!

The ARP Control introduces an improved method for protecting your Norcold or Dometic fridge while maintaining the original warranty ( Further reading see Magnuson-Moss Warranty Act ). The Fridge Defend pro-actively protects your fridge rather than responding after a failure has occurred such as the present recalls do. This is an improvement upon factory control methods, thus Magnuson–Moss Warranty Act insures that you can improve your safety. ( Also see: Restore Factory Settings )

ARP + Fan Control

Star Rating: Super great service. Paul went out of his way help me while I installed the ARP Basic unit in a friends Class A motor home. I installed an ARP with fan control in my Class A MH. I just love how the Fan Control has improved the cooling in my Norcold.

So what is up with the bar graphs and the testimony from LaPlatrosa?
Out of the total number of customer ratings, these graphs show how many people that bought the Fridge Defend by ARP and felt that their family was safer, their fridge was more reliable, and that the ARP + Fan Control made their fridge more efficient. Please note that none of the pets that were left alone in the RV reported , but an independent survey (the dog next door) stated that 100% of pets insist their master is goofy if they do not purchase a Fridge Defend by ARP Control for safety. LaPlatrosa left this review of the ARP Control on 9/5/2015, we love Happy Campers!
