Also, a blown high voltage fuse could be the cause, in which case you'll need a Replacement Fuse Kit, part number 105349-01.
What causes a U.S. Boiler Company Boiler display to be completely dark but the fan is running?
If your U.S. Boiler Company Boiler display is completely dark, but the fan is running, it indicates a lack of 24Vac power to the control. Check for loose 120Vac connection wiring between the boiler J-Box and the transformer, as well as loose 24 Vac connection wiring between the transformer and the control.

Why is my U.S. Boiler Company K2 Boiler experiencing ignition failure?
If you're experiencing ignition failure with your U.S. Boiler Company Boiler (models K2-080 through K2-180), where the flame fails after 5 restart attempts, it could be due to several reasons. Check for no gas pressure or gas pressure below the minimum value on the rating plate. Ensure the gas line is fully purged of air. Other potential causes include a defective electrode, loose burner ground connection, defective ignition cable, or a defective gas valve. Also inspect for a defective or fouled electrode, or a plugged drain line in the trap. If the flame rod isn't detecting a flame or the condensate trap is plugged, these could also be the cause.
