The Norcold N3150 is a 3-way fridge, so it runs on LP gas, 120V AC or 12V DC. On propane, an absorption fridge this size uses only a small amount of gas, and a typical 20 lb tank lasts a long time on the fridge alone. Actual use depends on the outside temperature. The N3150 has been discontinued by Norcold, and the replacement is the Norcold N4150. See our Norcold replacement guide.
