Atwood Furnace Model AFMD20121 Tune-Up Kit
$37.98
$28.71
Note: Older AFMD20121 furnaces used a curved blade sail switch (31093), newer furnaces use a flat style blade sail switch (33063). As there is not an accurate SN break you need to determine which sail switch is applicable to your furnace as this will determine which kit you will need to order.
