For those looking for an alternative option to the dreaded Norcold recall box that stops your refer from working every time it gets wet, this may be it.
The ARPrv Controller
is made by the same people who make the Amish replacement cooling units. It not only monitors the boiler temperature (like the Norcold recall box does), but it also monitors unsafe non-level conditions that can tend to shorten the life of the cooling unit. You can also get a remote controller unit to mount inside the RV. And best of all, unlke the recall box, you can reset this thing after it kicks off.
It looks just as easy to install as the Norcold recall box, and I believe they are selling them for only around $115.
Here are two links I found for this unit...
ARPrv | RV Refrigerator | Controller | Installation by Cooling Unit | RV Fires
... and an older site by the same people here
I have upgraded to a residential refrigerator in my motor home, so I have not had occasion to personally use this unit or research it any further than noting the web pages above. Therefore I am not in a position to personally recommend this unit as a recall replacement. I am posting this only because it looks like an extremely interesting alternative to the troubled Norcold recall. Please do your own research.
