Gas fired boiler no heat
I have a old gas fired weil-mclain boiler my thermostat was all the way down "off" during storms with 70mph & brief power glitch I tried turning the heat up but no heat but I could hear it kicked on I checked it no pilot and a clicking sound

have you tried hitting the spill switch on the vent?
Have you tried relighting the pilot?
Is it a continuous click while it’s calling for heat? Clicking could be coming from the a bad gas valve which could also explain why your pilot is out1 -
I shut off the gas and electricity because i was sure what happened

Sorry new to forums my fiance took care of all this but unfortunately he passed away I didn't know if it was safe to light etc I seen that green wire wasn't sure

sounds like it is something you are unfamiliar with and not comfortable touching which is fine. My suggestion would be to have someone qualified to come look at it if that’s the case.
Can even post where you live and there may be someone on here close by or someone who can be recommended too you that you can trust

Ty for replying I appreciate it I'm on this forum because I have no other options to get someone to help

If you shut off the gas, then you need to light the pilot. There should be step by step instructions right on the inside of the door you removed. Got a BBQ lighter?

In the pictures there's a loose C wire from the fan relay I wasn't sure if that's a problem or if it's supposed to be disconnected I shut of the electrical breaker & the square d fuse box switch on the side of the boiler & the gas to the boiler I have a bbq lighter I was leary of trying to light it without knowing if the forked spade green C wire should be connected to anything

Got to ask. How do you know that the pilot is out? There is a metal plate that typically needs to be removed to see the pilot. Seems like it's still in place.

Is the green wire connected to the "c" terminal? It probably bonded one side of the transformer to ground before the wiring was um….reworked.

Yes it's on the C fan relay I figured it was a ground that hooked on a screw

I looked through hole

Where are you located? Maybe we can find a benevolent soul. I really don't think that you should be doing these things yourself. There's an awful lot of risk involved. That wire has nothing to do with the pilot light.

So you turned off the gas and power at an earlier time. Your system probably has a standing pilot and you will need to light it.
Do you smell gas? If you do, turn the gas off at the boiler.
Do you have directions on the side of the boiler? If so, you will need to re-light the pilot light using the directions. Read the direction and be careful.
If the pilot is hard to reach, In the past I have talked some homeowners through the procedure via the phone. A trick is to us a length of pasta. Its longer than a match or lighter and should reach. Light one end of the spaghetti while following all the safety precautions supplied with the directions.
If you are not comfortable with doing this, its time to call a pro.

today I learned, spaghetti is flammable
known to beat dead horses

Never met a pilot, that could not be reached with a BBQ lighter.

Spaghetti works, especially when there isn't a BBQ lighter handy.👍️ "✋" Try it.

Just tried the spaghetti. Does work. Not great but will work in a pinch. My poor wife.... didn't quite know what she was getting into!!!

Mine requires a 13" reach through a small hole. I use a "fireplace match" with an extension!
Trying to keep Bernie burning!

Hi, I wouldn't be surprised if someone here would be willing to use something like Facetime to walk you through the process of figuring it out. Most important is staying safe. I like having tools around. A simple analog volt-ohm meter is probably under $20 and if you had one, it would make the troubleshooting process safer and go better. Then you would get to have this nifty tool to keep and show off! Just a thought. 😊
Yours, Larry

Thanks foe the reply Larry, I have a new digital multimeter my fiance bought before he died but not a analog one & no I've never used one I didn't know if it was a simple fix or the wire got blown off by high winds coming down the chimney I can light the pilot "doesn't need spaghetti" I have my daughter here & wasn't going to risk frying anything or setting it on fire if something got disconnected etc Thanks for your suggestion & reply

Its a ground. Ground it.

You said you shut off the gas. How did the pilot light itself?
Is the arm on the vent damper vertical or horizontal?
0 -
Reading these posts, are we sure the boiler has a standing pilot? My first thought was that it was an intermittent pilot and the clicking noise was the pilot flame not igniting.
1 -
Look at the pictures in the first post. Clearly a standing pilot. Thermocouple is visible

My guess is from 75-80 mph wind gust and a power glitch

That loose wire was purposely taped back some time ago, I don't believe it is part of your problem.
You must get the pilot lite before anything can proceed.
Your pressure gauge shows very little water pressure in the boiler. It should read 12-15 PSI. You need to add water to the system.
Did you ever state where you are located……just city & state. ??

Ok so I lit the pilot but it wont stay lit after releasing the reset button I noticed the spill switch is tripped as well

Might need a new thermocouple. Maybe. I am assuming that you help the button for 60 seconds after lighting ?
1 -
How did you determine that the spill switch is tripped?

Chicagoland, or downstate?
Trying to squeeze the best out of a Weil-McLain JB-5 running a 1912 1 pipe system.0 -
Downstate I'm a hour south of Springfield il

Keep trying. Release the depressed pilot button as if you are in slow motion. Sometimes you need a few tries before it will light. Again…slowly.
1 -
If the button doesn't stay in after holding it for a minute or so most likely the thermocouple is bad, mispositioned, or the pilot burner is mispositioned, dirty, or needs adjustment. It could be a bad gas valve but that is like 1/100 in the possibilities.
3 -
Agreed, but if the inexperienced OP goes too quickly and flicks the button up as soon as the pilot lights the flame can easily go out. Holding for a few seconds or longer and slowly lifting off the button as it rises is a good practice for someone who doesn't light a pilot often. Then they can turn it from the pilot selection to inservice as the pilot stays lighted.

It needs to heat the thermocouple and that takes some time. i haven't owned anything standing pilot in a long time but it would give it a count to 60 or so when i did.
