What to check first
Identify the heater model, review its service interval and inspect only after cooling and depressurizing according to the manual.
When to get help
Ask for seasonal service and model-matched replacement if needed; avoid assuming every heater takes the same anode.
Your RV’s make, model and component instructions control. Stop use and seek qualified help for propane odor, smoke, active electrical danger, unsafe braking or other immediate hazards. This guide does not diagnose your RV or establish part compatibility.
Next step
Check the exact component manual and model number before following a model-specific procedure.
