What This Does

The 51802 is the piezo igniter with integrated knob that generates the ignition spark for your Dometic RV range or cooktop burners. Meaningful functional benefits:

• Sparks propane ignition without external electrical power
• Self-contained mechanical operation — no batteries required
• Reliable ignition for range burners and ovens

⭐ No External Power Required

Standout feature: piezo ignition works without any external electrical power — meaningful for buyers who want reliable range ignition even when the RV is off-grid, off-battery, or otherwise without 12V DC available. The mechanical piezo generates its spark from the physical action of turning the knob.

⚠️ Professional Installation Recommended

Installation involves gas appliance service — removing the failed igniter, installing the replacement with correct alignment, and ensuring the ignition spark path is undisturbed. Installation should be performed by a qualified RV service technician unless you have prior experience with gas cooking appliance service. Always test all gas connections with leak detection solution before returning the appliance to service.
