Our kerosene refrigerators use Aladdin burners. To get the right part you need the burner number (located on the side of the burner or burner knob), and the make and model of refrigerator. #23 and #32 burners are the most common. #21, #21BC and #B burners are rare.
Note: The #23 Burner interchanges with any burner except #32. Most refrigerators use a #23 or similar burner. Most Sibirs and a few older Dometics use the #32 burner. Parts will not interchange between burners. If not shown above, kerosene burner parts are not available.
