What consequence arises from a partially frozen pump gear in an oil heating system?

A partially frozen pump gear in an oil heating system can lead to increased amperage. This occurs because the motor has to work harder to overcome the resistance created by the frozen components. When the pump gear is partially frozen, it obstructs the normal flow and operation of the fuel delivery system. As a result, the motor draws more electrical current to deliver the required performance, leading to elevated amperage levels.

Increased amperage not only indicates the system is working inefficiently but can also put unnecessary stress on the motor and electrical components, potentially leading to other operational issues if not addressed. Understanding this relationship helps in diagnosing and maintaining oil heating systems for optimal performance and longevity.
