Atwood Furnace Model AFMD16121 Tune-Up / Repair Kits
Note: Older AFMD16121 furnaces used a curved blade sail switch (31093), newer AFMD16121 furnaces used the flat blade sail switch (33063). If you wish to upgrade to the flat blade upgrade kit then select kit #3. As there is not an accurate serial number break we suggest that you determine which sail switch (curved or flat blade) is applicable to your furnace as this will determine which kit you will need to order.
