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.
