RV GFI | RV GFCI | Norcold Safe | Dometic Safe | Heater

Does your fridge have an RV GFI or RV GFCI to keep your Norcold safe or Dometic safe? The electric heater needs this protection.

Does your RV have an electric heater GFI?

Dometic GFI or GFCI

The image to the left shows an electric heater GFI on the power supply to an RV fridge. A GFI or GFCI plug are generally the same device. One of our customers reported that the ARP Control turned off their fridge. They turned off the ARP to restart their fridge. Luckily this event happened at night, thus when the fridge restarted on 120VAC the owner of the RV went out to look and witnessed the bottom of one heater glowing red hot.

It is our opinion that the heater could have shored internally. If this is the case, a GFI or GFCI type receptacle may prevent this type of failure mode. A GFI receptacle on your fridge will shut down the fridge if any short to ground occurs. It just makes good sense to take this safety measure on your Dometic fridge.


RV GFI

We encourage you to check your fridge to see if the manufacture has installed a GFI on your fridge outlet. Some manufactures power the fridge from a GFI plug that is located in another part of the RV, such as the bathroom GFI. A GFI receptacle is one part of a package of safety equipment which includes the ARP Control and a fire extinguisher in your RV.
