Frigidaire 5303303673 Range Burner Knob – Burner Won't Control Temperature or Knob Is Broken, Missing, or Slipping
A broken, missing, or slipping burner knob turns a simple cooking task into a guessing game — you can't set heat accurately, you can't tell if the burner is on or off, and a loose knob on a gas range is a genuine safety hazard. The 5303303673 is the OEM burner control knob for Frigidaire gas and electric ranges, with a precision D-shaft insert that locks onto the valve stem and permanently molded temperature markings that won't fade or wear off. Choose OEM for factory-original fit, or XPart for a premium aftermarket alternative at a lower price point.

Burner knobs on the same range age at the same rate — heat cycling, UV exposure, and daily use affect all of them equally. If one knob has cracked or faded, the others are close behind. Replacing all knobs at the same time costs a fraction of multiple service visits and gives your range a consistent, like-new appearance. It also eliminates the mismatched look of one new knob among worn originals. Check all knobs for D-shaft play, cracking at the base, and legibility of markings while you're already at the range.
