Anybody having problems with CDB100 furnaces lighting incostintentlty? It seems the module de energizes the igniter too soon after opening gas valve. Already changed igniter(oem), gas valve and ignition module. Gas valve outlet pressure is 3.5″ and 120v to igniter. Just put the universal replacement igniter that came with the new module because it claims twice the surface area and its lighting…for now.
