1107-2 Control Not Flashing

in Gas Heating
Hi all - have a Weil McLain CGA4 boiler with the 1107-2 IBCM (not to be confused with ICBM). We had an over-voltage event and lost some appliances, the furnace was one of them. I get no lights on the board at all - wondering if this is a good bet to try swapping it out or if there are some diagnostics that I can do prior to buying a new board? When I set the thermostat to heat, the circulating pumps come on, but I get no lights or anything on the furnace at all.

    If it wasn't apparent - this is a hot water boiler, natural gas and it circulates through radiators. Thanks!!!

    Is there power to the board?

    I expect that that board is toast. If the surge was bad enough to get appliances, it surely was bad enough to get the board.

    I think you need a new board.
