Furrion Stove / Range: “Oven lights then goes out”
warning RV stove & oven problems
What it means
The oven ignites but the flame extinguishes once the knob is released or shortly after. This is the classic flame-supervision-device (thermocouple) fault: the thermocouple must be heated by the pilot/burner flame to generate the small voltage that holds the gas safety valve open. If it does not get hot enough, the safety valve closes and shuts off gas, which is the device working as intended on a marginal flame.
Most likely causes
- Thermocouple tip not fully in the flame, bent, or misaligned so it never gets hot enough most likely
- Loose thermocouple connection nut at the gas valve common
- Knob released too soon before the flame and thermocouple stabilized (hold ~5+ seconds) common
- Dirty pilot/burner producing a weak, lazy flame common
- Worn-out thermocouple that no longer generates sufficient voltage less common
- Inadequate combustion air in a fully closed oven causing flame to weaken less common
Safe checks you can do yourself
- When lighting, hold the knob in for at least 5 seconds (longer if needed) so the thermocouple heats before releasing.
- With the oven cool and gas off, gently reposition the thermocouple tip so it sits directly in the pilot/burner flame.
- Snug the thermocouple connection nut at the valve hand-tight plus a slight turn; do not overtighten.
- Clean any soot or grease from the pilot and thermocouple tip.
- Try the first burn with the oven door cracked a few inches for 3-4 minutes to confirm a combustion-air issue.
- Confirm the flame is mostly blue and steady, not yellow and lazy.
How to reset / clear Oven lights then goes out
- Turn the oven OFF and wait a few minutes.
- Relight per the manual, holding the knob in long enough for the flame to stabilize.
- Release slowly; if it drops out, repeat after reseating/cleaning the thermocouple.
- If it still drops out after a clean reseat, plan to replace the thermocouple.
When to call a technician
Call an RV/LP technician if the flame will not hold after reseating and cleaning the thermocouple, if the thermocouple needs replacement and you are not comfortable doing it, or if you ever suspect the safety valve is not shutting off gas when the flame is out.
