Why Choose This Burner Control Knob?
Not all replacement knobs are created equal. Generic aftermarket knobs often fit loosely, fade quickly, or lack the tactile precision of the original. This Greystone CF-RV17 CF-RV21 replacement burner knob is sourced through authorized channels, ensuring the same fit, feel, and durability as the factory-installed part. Whether you're a full-time RVer or a weekend warrior, a properly functioning burner control knob is essential for safe, reliable cooking on the road.
The burner control knob is one of three knob styles available for the CF-RV17 and CF-RV21 — see the comparison table below to find the exact knob type you need.
Compare Greystone CF-RV17 & CF-RV21 Replacement Knobs

Frequently Asked Questions
Which knob do I need — burner, igniter, or temperature?
The burner control knob (this listing) regulates gas flow to each burner. The igniter knob controls the spark for ignition. The temperature knob controls oven heat. Check which knob is damaged or missing on your range before ordering.

Can I buy all the knobs I need in one order?
Each knob is sold individually (1 per order). Add multiple knobs to your cart to replace all damaged or worn knobs in one shipment.
