No heat
My boiler stopped working at the end of spring. The pilot was lit but it didn't fire. The house vacant and the weather was nice so I put it off. Now I'm trying to ready the place to move in. A Weil McClain CG 4 spdn boiler. I dont know anything. Figuring it out as I go. I've replaced the rollout switch, spill switch and damper motor. I let a couple wires touch and burnt out the transformer so I replaced that as well. I can jump the damper and it will fire but the damper doesn't open. When I replaced the transformer I noticed some faint burn marks on the relay so replaced that. I was going to replace it anyway as I wasnt getting 24 or any reading between the C and Y terminals. Now when I replaced the relay and turn the unit on the transformer makes a very loud , rapid clicking. Any suggestions and help would be greatly appreciated.

Hi, are you sure it’s the transformer that’s clicking?, sounds odd more likely a relay, DON’T change any more parts your wasting money, post some pics of your boiler control.

Ok. Problem solved. I had attached photos as you requested but had to remove them to attach this image. A young man with some experience had been involved previously and he had jumped this device thinking it was no good. When I installed the new relay it was shorting hence the clicking. Just for giggles I removed the wire he used to jump it and the boiler fired right up. I wont be asking that guy for any more help. Lol. Thanks for your support.

I agree. That is the gas valve in your picture and should never have any jumpers added to it.

Is the damper opening? Please verify that it's working and opening when there is a call for the burners to lite. If that's not opening you could be in danger of CO2 poisoning.
