My boiler flue damper is not opening and the unit will not start up.
I do not believe it is the thermostat because I have tried three different thermostats and none correct the problem. I also tried bypassing the thermostat by connecting the red and white wires. The boiler still won't light.
I noticed that when the thermostat calls for heat, the damper as not opening, so I figured a bad damper motor was the problem.
I bought a new damper motor. When I plugged the new motor in, the damper closed. When I turn up the thermostat to call for heat the new damper will still not open, so the unit will not light.
What can I try next?
