KDRS505XSS03 Whirlpool Double Oven Gas Range used

30-inch stainless steel gas range with a double oven five-burner cooktop Pullout rack, total 3 oven racks included range is used, so it has some wear and tear, but it functions perfectly well except **2 knobs (for both back burners) which do not turn and need repair/replacement** I'm asking $350, which reflects its condition Parts: PartSelect #: PS11756456 Oven rack [compatible WPW10570870] PartSelect #: PS16620328 PartSelect #: PS11752381 Burner cap PartSelect #: PS11752259 Knob PartSelect #: PS11749521 Centre burner cap PartSelect #: PS3407761 Griddle PartSelect #: PS11751372 Grate kit
