Frequently Asked Questions

How do I know if my combustion chamber needs replacement?

Common signs include excessive soot production, difficulty igniting, reduced heat output, unusual odors during operation, or visible cracks and corrosion on the existing chamber. If your heater cycles on and off frequently or produces black smoke, the combustion chamber may be compromised.

Is this combustion chamber difficult to replace?

Replacing the combustion chamber requires disassembly of the heater unit and basic mechanical skills. You'll need to access the burner assembly, remove the old chamber, and install the new one following Dometic's service procedures. If you're not comfortable with RV appliance repair, consider having a certified RV technician perform the installation.

Will this fix my heater if it won't stay lit?

A damaged combustion chamber is one common cause of ignition and flame stability issues, but not the only one. If the chamber shows signs of deterioration, cracks, or heavy carbon buildup, replacing it often resolves these problems. However, fuel delivery issues, glow plug problems, or control board failures can also cause similar symptoms.

How often should the combustion chamber be replaced?

Combustion chambers don't have a set replacement interval—they're replaced as needed when they show signs of wear, damage, or performance degradation. Regular maintenance and proper fuel quality can extend chamber life. Inspect the chamber during annual heater servicing for cracks, corrosion, or excessive carbon deposits.
