Hello All, I have a zone on my boiler that is not getting heat. So I have been getting information on how boilers work. I can not find any zone valves on my boiler. All I have are relays that are mounted to the boiler that are wired to the circulation pumps. I don't think this is too common because everything I've watched or read refers to zone values turning on the circulation pump and heat. Thanks Joe

Hi! I have a question. Recently my furnace started to act funny. It starts and heats up fine but towards the middle/ end of cycle you can hear the air flow slow then speed up and keep repeating and while it's doing that you can hear a rapid clicking sound. The burners will eventually shut off and the air flow will be normal again. I can hear the air flow difference through vents but worse next to furnace. I have new air filter and checked for blockage and build up. No error codes. Slow green light blinks while off then amber lights blinks slow flash while on. It's a luxaire furnace .Also the other day my thermostat wouldn't shut off heat at set temperature but that seems to be ok now unless it's going bad? Changed batteries. I'm not sure if this is safe to be running or not? Hope you can help! 😀
