I see your recommendation on bypassing the vent wire and disconnect the end switch! We have power, new gas valve but the damper will turn from open to open and doesn’t send the message to fire the boiler! Last night by a chance it fired then it **** off because the damper closed for no apparent reason! We are 20 degrees high today and it’s calling for heat and hot water t won’t fire up! A few years after we bought this house we had the Honeywell asquaric relay and then added this damper! We have a huge airflow coming into the utility room already! Please help!
