Yes. The Norcold Burner Tube 621073 fits the Norcold N300, N300.3, N301.3, N302 and N302.3 with a serial number above 738384. Your serial (15013899) is well above that, so it's the correct burner tube for your N302. The "R" at the end of the model number doesn't affect fit.
Replace the burner tube when it's rusted through, scaled or warped, or when the flame is lazy, yellow or lifting. A rusty burner is a common cause of weak cooling on LP gas and of the flame going out. While you're in there, clean the burner orifice and the flue and baffle so the new tube can give a clean blue flame. The 621073 currently has a 2–3 week lead time, and we're accepting orders now.
