Good Morning!
I am hearing a faint humming coming from inside my boiler and am trying to troubleshoot it. This is what I've discovered thus far.
1) If I turn power off to the boiler the humming stops.
2) If I turn the thermostat off but keep the power on the humming continues.
This very well may be a normal condition, but I had the boiler enclosed on three sides and may not have heard it before. I tore down one of the walls to access some piping before I fired it up. Yesterday we piped in a sprivent and bladder style expansion tank as well.
I'm not overly intimately familiar with everything concerning this boiler and am looking for things I should check.
Thanks in advance for any and all help.
