Dunkirk DXL170 boiler issue

[craigibc]

Hey,

My house boiler stopped working last night and hope someone with experience can guide me in the right direction.

I have not had good success with a heating guy over the last few years so I am going to go it alone for now.

Here is the basis of the issue. The Taco meter calls for heat and then the damper opens and there are 3 beeps and the furnace lights up and warms the boiler. Last night the 3 beeps and the boiler stopped firing. I have tested the control board and the damper to make sure they work and all seems fine.

No pilot and no beeps and no boiler firing. Everything seems great..... I even checked the rollout switch and it seemed to have continuity.

Antyhing I am missing?

Thanks,

Craig

this should be your boiler info....with a call for heat...check for 24volts at terminals 24v and 24vground at ignition module...if your good there ...trace issue to bad module...pilot/sensor assy. issue or Burner ground....
