Buzzing from boiler

JimmyNJJimmyNJ Member Posts: 92
Hi everyone: This morning as I was getting ready for work I heard a humming from the basement, I walked down and it appears to be coming from the boiler (it was firing). Could it be coming from the gas valve? Never heard this in my 12 years of living in the house. The only thing I can think of that may have contributed, is that last night our washing machine had a little bit of suds overflow which went on the floor and a little bit under the boiler and i used a shop-vac to suck it up. Could that somehow have screwed something up by my boiler burners? Is it a>safety issue? Potential fix? I've tried to post a video of the buzzing sound. Thanks for any help/guidance.

    Can you feel any vibration from the valve body?
    It could be from a transformer as well.—NBC

    @nicholas bonham-carter Is the "valve body" the grate that you can unhook that covers the burners? I didn't notice any vibrations beyond the usual when the boiler fires but could check more when I get home. Never heard that buzzing sound before so a little nervous that something is about to break on the boiler.

    To me it sounds like a relay. Can you post a pic with the door off and show the electrical components?
    I dont believe it's from the water unless it splashed over there.

    It's either the gas valve or a transformer. If you heard it from upstairs, it's most likely the gas valve.

    can you tell specifically where it is coming from? regulators, either at the boiler or the gas meter can make buzzing sounds when they fail along with the electrical components. you could have bumped an electrical component such that the sound is now conducting through something it wasn't before

    I was thinking of the gas valve body first, and secondly, the transformer.--NBC

    Thanks to all for the comments. Strangely enough (or perhaps luckily enough) I have not been able to replicate the noise since, so whatever it was that decided to "buzz" when the heat was on the other morning apparently went away on its own.

    @JimmyNJ Relays are know to do this at times. Occasionally they do not pull in just right and the magnetic force causes it to buzz. If this happens and you want to test this theory. Turn the burner off then back on. If it comes and goes it is probably the motor relay. You may be able to feel it buzzing. I have not found this to be indicative that it is going to fail. If the noise it bothersome, change it out.
