Tanya W. for Model Number SC8720EDB Whirlpool 30-in 4-Burner Gas Cooktop (Black)
Answer Tanya, the aeration pan is part number 3401X055-09 and the burner grate is part number Y04100335. These parts come one per package. Unfortunately, the knobs have been discontinued and are no longer available. Thanks for your inquiry.
