Frequently Asked Questions

Q: How do I know if I need to replace my burner jet?

A: Common signs include uneven flame distribution, flame that's too high or too low, yellow or orange flame color instead of blue, or difficulty maintaining consistent heat. If cleaning the burner doesn't resolve these issues, the jet likely needs replacement.

Q: What does the #45 jet size mean?

A: The number indicates the orifice diameter in thousandths of an inch. A #45 jet has a specific opening size designed to meter the correct amount of gas for your burner. Using the wrong size jet can cause performance and safety issues, so always replace with the exact size specified for your cooktop.

Q: Can I install this jet myself?

A: Yes, most RV owners can replace a burner jet with basic tools. Turn off the gas supply, remove the burner grate and cap, unscrew the old jet, and install the new one. Always check for gas leaks with soapy water after installation and ensure proper flame operation before regular use.

Q: Will this jet work with LP gas and natural gas?

A: Burner jets are fuel-specific. This jet is designed for the fuel type your Dometic cooktop was manufactured for (typically LP/propane in RVs). Converting between fuel types requires different jets with different orifice sizes. Verify your cooktop's fuel type before ordering.
