Furnace 'False Starts'

just wanted to throw this out there before i call someone to look at this.
our 3 yr old furnace (weil-mclain) seems to make that click ‘on’ sound and ignite then goes no further and just stops. this is happening when there actually isn’t a call for heat from the thermostat.
it’s working fine when the thermostat requests heat. this is just happening in it’s ‘down time’.
any ideas or suggestions?
No one is going to be able to diagnose this definitively via computer. Sounds like a vent damper thing, but it can be several other things.
I’m not encouraged by your vent damper being disconnected, though. You need to fix or replace that quickly.
sorry for the lack of info…i’ll try though: this is a hot water system with 2 zones/2 separate thermostats. One thermostat seems to work fine and fires the furnace/works when there’s the call for heat…the other produces the mis-starts ( i thought it was doing this without a call for heat). sorry that’s all i know about this…also it’s a williamson, not weilmclain.
also as far as clicks go i think our our plumber disconnected the vent dampener so it’s always open since it was malfunctioning. so there is the one click and what sounds like an ignite, then off.
maybe a wiring problem?
oh and it was converted from gravity-fed hot water wood/coal burning furnace into circulator-forced furnace burning oil. So efficiency in not the name of this game.
I try to convince myself that if time will get tough and I will have no money to pay for oil. I will burn furneture for heat :)… And I can dispose corpses in it for fee 🙂
chaps. I completely agree. We got the house a year ago and will replace boiler coming spring. We would do it past summer but in light of continued recession, we wanted to keep more cash on hands in case of employment difficulties, etc.
I guess that makes three clicks!
Too true MP.
Hey, OP do you have a circulator pump?
Bobjohn, I respectfully submit that it is time for a new boiler…. LOL

what is the zone configuration…zoned by pumps or zoned by zone valves?…is it a primary pump setup or a primary/ secondary setup?…what is the zone controller?
Bobjohn, that is a terribly inefficient and costly way to operate your boiler. For SHAME!
Steam Man, maybe CGmodern is hearing a circulator relay pull in while the boiler is already up to temperature?
Is this steam or hot water? Standing pilot ignition or intermittent? We need to know these things!
my furnace built in 1910. It turns itself on when water temperature goes bellow 150F. Thermostat controls the water circulator not the burner.
thanks steamman…i’ll look into it better and check back. really appreciate your explanantion!
