Hi,
I have a 1988 Dolphin with a Dometic 2401 refer. I do not know for sure if it is a 2-way or 3-way type or refrigerator. The selector switch can be placed in the "Gas", "Elec" or "Off" positions. I know that it works on gas and I know that the heating elements work when I am plugged into 110V power (and switched to the "Elec") position. Does anyone know how to verify the "Elec" position heating the elements with 12VDC (thus making it a true 3-way refer)? Or, perhaps someone may know right away that the Dometic 2401 did or did not offer a 3-way model? Thank You, Riverman77
