What to check first
Stop if you smell propane. Otherwise record the model, which burners work and the symptom without disassembling the gas path.
When to get help
Ask for qualified appliance service; do not bypass safety devices.
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.
