When dealing with suspected water intrusion in an electrical component, the most prudent initial step is to inspect, dry out, and if necessary, replace the component. This approach is critical for several reasons.

First, inspecting the component allows you to assess the extent of the water intrusion and determine whether the component is still functional or permanently damaged. Just replacing the component without inspection might lead to unnecessary expenses if the issue is minor and can be resolved with drying and cleaning.

Secondly, drying out the component is essential because moisture can lead to corrosion, short circuits, and other failures. Ensuring that all parts are dried thoroughly can prolong the lifespan of the component and enhance safety by reducing the risk of electrical faults.

If, after inspection and drying, the component shows significant damage or corrosion, then replacement becomes the next logical step. This method serves both to preserve the integrity of the electrical system and to ensure safety by addressing the root cause of the issue rather than just treating the symptoms.

The other options do not provide the correct order of operations needed to effectively manage water intrusion. For instance, replacing the component immediately may overlook the possibility that the component could be salvageable. Calling a professional technician might be appropriate in complex situations, but first addressing the issue personally helps in understanding
