      If your Weil-McLain boiler's display screen is blank and it's not responding to a call for heat, first, examine the wiring for any short circuits or incorrect connections. Next, check the 3-amp low voltage fuse on the control. Finally, verify the transformer connection to the control, referring to the wiring diagram, and confirm that the transformer is outputting 24V.
