What is the furnace make and model number? Are you getting any LED flash code?

Customer: replied 1 year ago.
Burnham series 2
No flashing I didn't take the cover off yet though
Expert:  Tim H. replied 1 year ago.

Do you have zone valves?

Customer: replied 1 year ago.
Not sure what that is
Expert:  Tim H. replied 1 year ago.

Single thermostat in the house or more than one?

Customer: replied 1 year ago.
Sorry I'm an idiot l
Customer: replied 1 year ago.
2 thermostats on the same floor
Expert:  Tim H. replied 1 year ago.

Are they both for heating?

Customer: replied 1 year ago.
only heat. No centra air
Expert:  Tim H. replied 1 year ago.

Do you have zone valves down near boiler? They may look like this. Sometimes a different brand may be used other than Honeywell.

Customer: replied 1 year ago.
2 of them
Customer: replied 1 year ago.
The blue cap is buzzing. This is the picture
Expert:  Tim H. replied 1 year ago.

Take the cover off and see if the valve is open. The way you tell is to push the small lever over and if there is no resistance, then it's open. If you turn off that zone and the lever pushes with some resistance, then that valve is closed. Need to know if it's open or closed.

Customer: replied 1 year ago.
The cover off the furnace or the blue cap
Expert:  Tim H. replied 1 year ago.

Cover on zone valve. The one you sent me a picture of.

Customer: replied 1 year ago.
Ok sorry
Customer: replied 1 year ago.
They are both on auto? Not on/main
Expert:  Tim H. replied 1 year ago.

Take the cover off and see if the valve is open. The way you tell is to push the small lever over and if there is no resistance, then it's open. If you turn off that zone and the lever pushes with some resistance, then that valve is closed. Need to know if it's open or closed.

The temperature really dropped I'm in Staten Island , Nyc it's like 5 below
Expert:  Tim H. replied 1 year ago.

I understand your concerns since it's cold there. That's why I need you to do the things I mention so we can try and figure out what's going on.

Customer: replied 1 year ago.
Move the levers both to open
Expert:  Tim H. replied 1 year ago.

Now lets see if any heat starts coming up the pipe.

Expert:  Tim H. replied 1 year ago.

Tell me if the boiler kicks on.

Customer: replied 1 year ago.
Didn't kick on. Cap is still buzzing I don't see a pilot light on
Expert:  Tim H. replied 1 year ago.

Is your boiler electronic ignition or a standing pilot? Standing pilot would be the pilot on all the time.

Customer: replied 1 year ago.
This is what looks like I when i took the cover off
Expert:  Tim H. replied 1 year ago.

That would be standing pilot. Do you know how to light pilot?

Customer: replied 1 year ago.
Not really
Customer: replied 1 year ago.
On the water tank it has a black pilot switch
Expert:  Tim H. replied 1 year ago.

There is a knob on your gas valve. Turn to pilot position, push down, HOLD, and reach in with a long match and light pilot. Continue to hold down for about 60 seconds, then release knob and turn to ON position.

Customer: replied 1 year ago.
Looking for a match
Expert:  Tim H. replied 1 year ago.

OK

Customer: replied 1 year ago.
I have regular matches.. Not long ones.
The pilot on the furnace not the water tank correct
Expert:  Tim H. replied 1 year ago.

The one on the picture I sent you. Blue arrow.

Customer: replied 1 year ago.
Where am I actually putting the match?
Expert:  Tim H. replied 1 year ago.
Customer: replied 1 year ago.
I got the pilot light on , still loud buzzing, and I didn't hear the furnace kick in yet
Expert:  Tim H. replied 1 year ago.

Did you turn valve knob to ON

Customer: replied 1 year ago.
lol
Expert:  Tim H. replied 1 year ago.

If pilot is lit and valve on, either you have a bad thermocouple or not calling for heat. Are the levers on zone valves still in the ON position instead of AUTO?

Customer: replied 1 year ago.
Expert:  Tim H. replied 1 year ago.

Probably have a bad thermocouple then. This can be pulled out, brought up to a local hardware and replaced. It is on the pilot assembly. The thermocouple is at the end of this copper line.

Customer: replied 1 year ago.
What about the buzzing?
Expert:  Tim H. replied 1 year ago.

Nothing to worry about. Zone valves do that sometimes.

Expert:  Tim H. replied 1 year ago.

Did you want to work further on this or can we close question out?

Customer: replied 1 year ago.
Close it out thank you.
It was the following that was buzzing.
Expert:  Tim H. replied 1 year ago.

Your vent damper. Have all your questions been answered?

Expert:  Tim H. replied 1 year ago.
