Oil Burners License Practice Test

The first step when an oil burner will not start is to check for power supply. Ensuring that the burner has power is essential before diagnosing other potential issues. A lack of power could stem from various sources, such as a blown fuse, a tripped circuit breaker, or disconnections in the wiring. If the burner is not receiving electricity, no other troubleshooting steps will have any effect, as the unit will not operate without power.

Once the power supply has been confirmed and is functioning properly, it becomes possible to move on to other aspects like checking the fuel level, cleaning components, or resetting the thermostat. These subsequent steps are important, but they rely on the burner having an adequate power supply to begin functioning in the first place.
