What to check first
Record make/model, thermostat setting, supply mode and fault indicator. Check only accessible vents for blockage.
When to get help
If you smell propane, stop use and seek qualified help. Otherwise schedule appliance diagnosis before replacing components.
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.
