What might be indicated by a noisy oil burner motor?

A noisy oil burner motor is often an indication of issues with the motor itself or with the pump. This could manifest as unusual sounds such as grinding, squealing, or knocking, which are signs that components may be worn out or failing. A malfunctioning motor can affect both the performance of the burner and the efficiency of the heating system. If the pump is faulty, it may not be delivering the correct fuel flow, leading to improper combustion and noisy operation.

The correct choice highlights that maintenance or replacement may be necessary to ensure the burner operates safely and effectively. Regular inspection of the motor and pump will help prevent larger issues in the system down the line.
