Does your boiler have a vent damper? is it open?

Ok, next check the blocked vent switch attached to the bottom of the draft diverter bell (see pics). Push the button that's between the 2 wires. If it clicks you have reset it and the burner will fire up with any luck

The draft hood is working fine the furnace is not firing
Expert:  Rick replied 9 months ago.

Not what I said. I said to check the blocked vent switch on the bottom of the draft hood.

Expert:  Rick replied 9 months ago.

I posted a picture of the switch

Done. I am a general contractor with 45 years of experience and I still have not got it to work I know the basics
Expert:  Rick replied 9 months ago.

Ok, next jump out the flame rollout sensor that's above and just outside the burners. If you have a multi-meter you can also check for 24 vac at the gas valve.

I am running to the hardware store to get a new one of those
Expert:  Rick replied 9 months ago.

A new what? flame rollout sensor?

Expert:  Rick replied 9 months ago.

Did the burner fire up when you jumped it out? BTW you won't find one at a hardware store. Only a plumbing supply house is likely to have one

Customer: replied 9 months ago.
What you sent a picture of? You say a plumbing store will only have one of those
Expert:  Rick replied 9 months ago.

Yes. Did the burner fire up when you jumped it out?

Expert:  Rick replied 9 months ago.

How did this work out?
