What type of components are replaced if the igniter is consistently operating at high amperage?

When the igniter is consistently operating at high amperage, the appropriate component to replace is the hot surface igniter. This situation often indicates that the igniter is struggling to reach the necessary temperature to ignite the gas properly. A hot surface igniter that is malfunctioning may draw more current than normal, which can lead to premature failure or inconsistent operation.

Replacing the hot surface igniter helps ensure that it can effectively reach the required temperature for ignition without exceeding safe operational parameters. This is crucial for the safe and efficient operation of the gas appliance. In contrast, the gas line connections, ignition module, and flame sensor do not directly address the issue of high amperage in the igniter, as their functions pertain more to the gas delivery, control, and flame detection processes, respectively.
