Gas Range Knob Kit Universal For: RK203, 4590-211
Safety first: Knobs install by hand with the gas supply off; no tools or disassembly of gas components are required.
Replace missing or worn range controls with this ERP replacement gas range knob kit. The kit includes five black knobs, ten shaft inserts, and surface and oven overlays so the knobs can be matched to a wide range of compatible gas ranges. Worn, cracked, or missing knobs make burner settings hard to read and can leave a range unusable. This kit is a direct replacement for the listed part numbers. Verify the appliance model and original knob dimensions before ordering.
