Quick Answer
A propane range that ignites but won't stay lit often has issues with air flow, burner orifice size, or a faulty igniter. Check the burner orifices for blockages and clean them with a small brush. Adjust the burner orifices or replace the igniter if necessary.
Inspecting Air Flow and Burner Orifices
Inspect the burner orifices for blockages from debris, soot, or grease. Clean the orifices with a small, stiff brush (such as a bottle brush) to restore proper air flow. Make sure not to scratch the orifices, as this can damage the burner. Use a propane range-specific cleaning solution if the orifices are heavily clogged. A clogged burner orifice can cause inadequate combustion, making it difficult for the flame to stay lit.
Checking the Igniter
Check the igniter for signs of wear or damage. If the igniter is faulty, replace it with a new one. The igniter should be cleaned and maintained according to the manufacturer’s instructions. Typically, the igniter should be cleaned every 100 to 200 uses or at the manufacturer’s recommended interval. If the igniter is cleaned and maintained properly but still not working, consider replacing it entirely. A faulty igniter can prevent the burner from staying lit.
Adjusting Burner Orifice Size
If cleaning the burner orifices or replacing the igniter does not resolve the issue, adjust the burner orifice size to optimize air flow. Typically, propane ranges have adjustable burner orifices that can be fine-tuned for optimal combustion. Use a propane range-specific adjustment tool to adjust the orifice size. Adjusting the orifice size can help ensure proper air flow and combustion, making it easier to maintain a steady flame.
