boiler spark plug no spark

If the boiler spark plug in a boiler is not generating a spark, there could be a number of reasons why. Here are a few possible causes:

Dirty or worn electrode: Over time, the electrode in the spark plug may become dirty or worn, which can affect its ability to generate a spark. If the electrode is dirty, it may need to be cleaned using a wire brush or other cleaning tool. If the electrode is worn, it may need to be replaced.

Loose or damaged wiring: The wiring that connects the spark plug to the ignition control module or spark generator may become loose or damaged, which can prevent the electrical charge from reaching the electrode. Check the wiring connections and repair or replace any damaged wiring as needed.
