Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|
Auto ignitor without function | No ignition sparks heard or fewer than two sparks per second during start-up due to battery or contact issues. | Check and replace the battery if necessary, verify installation polarity, and clean oxidized battery contacts. | DIY Safe |
No flame | The auto ignitor functions, but no flame is produced due to a disruption in the gas supply. | Check gas cylinder fill level, open cylinder and appliance valves, verify/reset hose rupture protection and crash sensors, and check gas filters for oil contamination. | DIY Safe |
Operational Fault | Butane is unsuitable for heating at temperatures below +10 °C. | Use propane and switch on or retrofit the EisEx regulator heater. | DIY Safe |
Operational Fault | Reduced heating performance or blocked airflow. | Check the chimney opening for obstructions such as snow and retrofit a chimney extension if needed; remove carpets or obstructions blocking airflow in front of the heater. | DIY Safe |
Automatic igniter not working | Automatic igniter is not working or no ignition sparks are heard. | Check the battery, verify the correct polarity (plus/minus), and clean any corrosion on the battery contact points. | DIY Safe |
No flame | Automatic igniter operates, but no flame is formed. | Check gas cylinder filling level, open cylinder valve, reset hose rupture protection if fitted, check/replace gas filter, and ensure the crash sensor or device valve is open. | DIY Safe |
Operational Fault | Butane is not suitable for heating at temperatures below +10 °C. | Use propane and switch on the EisEx regulator heating (if available). | DIY Safe |
Heater malfunction | Heater is not operating correctly due to blocked flues or obstructions. | Check whether the flue opening is blocked (e.g. by snow) and remove any carpets or obstructions from in front of the heater. | DIY Safe |
Frequently Asked Questions
Q: What should I do if I smell gas in the vehicle?
Avoid ignition sources, extinguish open flames, do not operate electrical switches, mobile phones, or radios, do not start the engine, open windows and doors, evacuate all persons, close gas cylinders, and have the entire gas system inspected and repaired by experts.
Q: Can the heater be operated while driving?
Yes, provided a safety shut-off device (such as the Truma MonoControl CS or DuoControl CS complying with UN ECE regulation 122) is installed to prevent uncontrolled gas escape in an accident. If no such device is present, the gas cylinder must be closed during travel.
Q: How do I ignite the heater?
Open the gas cylinder and quick-acting valve, turn the control knob to thermostat position 1 to 5, press down to the stop for a maximum of 30 seconds while the automatic ignition sparks, monitor the flame through the mica window, and hold the control knob down for an additional 10 to 20 seconds after ignition.
Q: How do I turn on the Truma S 3004 / S 5004 heater?
Open the gas cylinder and quick-closing valve, turn the operating knob to a temperature setting between 1 and 5, press it down fully, and hold it for up to 30 seconds while ignition takes place automatically. Keep the knob pressed for another 10 to 20 seconds after the flame is established.
Q: What type of battery does the automatic igniter require?
Use only heat-resistant (70 °C) and leak-proof 1.5 V mignon batteries (type LR 6, AA, AM 3, part no. 30030-99200).
Q: Can I dry clothes or towels on the heater?
No. To avoid overheating and fire hazards, the hot air outlets must never be blocked, and items such as laundry must not be hung on or in front of the heater.
