Answer the question from the Australian user：My diesel heater is showing a ignition fault light but does end up starting but stops after a short time?
It sounds like your diesel heater is experiencing an ignition or combustion issue, even though it eventually starts. Here are a few common reasons for this behavior:
Fuel Delivery Problems: Ensure that the fuel lines are not clogged or obstructed and that the fuel filter is clean. Insufficient fuel flow can cause the heater to shut down shortly after ignition.
Air in the Fuel System: If there is air trapped in the fuel system, it can disrupt the combustion process. Try bleeding the fuel system to remove any air pockets.
Glow Plug Issues: The glow plug is essential for igniting the fuel, especially in colder conditions. If the glow plug is faulty or worn out, it may not heat up enough to initiate proper combustion, causing the system to stop shortly after starting.
Sensor Faults: The ignition fault light may indicate a problem with one of the sensors (like the flame or temperature sensor). If a sensor is malfunctioning, it could cause the system to stop once it detects an error.
Electrical Problems: A poor connection, faulty wiring, or issues with the control unit can lead to intermittent operation. Check for loose or damaged wires, especially around the ignition and fuel systems.
Exhaust Blockages: Ensure the exhaust pipe is clear of any blockages. Restricted exhaust flow can cause the heater to shut down due to overheating or a safety shutdown mechanism.
It's best to consult the heater's manual for specific troubleshooting steps or consider having it inspected by a professional to properly diagnose and fix the issue.
