Important Compatibility Note: This electrode is designed for SF series furnaces with serial numbers between 921403895 and 934701426. All Suburban serial numbers manufactured after January 1990 contain nine digits, where the first two digits indicate the year of manufacture, the next set indicates the week of the year, and the remaining digits are the serial number sequence.
