Quick Answer
Kerosene heater ignition issues can be caused by a faulty spark generator, dirty or clogged burner, or low kerosene levels. Check the fuel supply and clean the burner to resolve the issue. If the spark generator is defective, replace it.
Inspecting the Fuel Supply
To troubleshoot a kerosene heater ignition issue, start by checking the fuel supply. Ensure the kerosene level is above the minimum recommended level, usually around 1-2 inches below the top of the tank. If the level is low, refill the tank with fresh kerosene. Use a fuel stabilizer to prevent degradation and contamination. Check the fuel filter for blockages or corrosion and replace it if necessary.
Cleaning the Burner
Next, inspect the burner for any debris or soot buildup. Turn off the heater and let it cool before cleaning the burner. Use a soft-bristled brush to gently remove any visible debris. Use a small amount of kerosene to clean the burner, making sure to wipe it clean with a lint-free cloth. Check the burner orifice for blockages and clean or replace it if necessary.
Replacing the Spark Generator
If cleaning the burner and fuel supply does not resolve the issue, the spark generator may be faulty. Locate the spark generator, usually located at the bottom of the heater. Remove any screws or clips holding it in place. Inspect the spark generator for any signs of wear or damage. If damaged, replace it with a new one, following the manufacturer’s instructions for installation.
