Valliant model 6a92-140 ei gas fired steam boiler

[Buddy Felt Jr]

My furnace comes on for about 1 minute then shuts off. When it is off, a slight sound is emitted from the motherboard area, like a buzzing, near what I think is the relay switch. Any ideas?

Most circuit boards have an LED that will blink, in different patterns, to notify you of a problem. Example would be; three rapid blinks means (fill in the blank). If you have the manual for the boiler it might have the information in there or perhaps on one of the panels that covers the control section of the boiler. Problem is that most supply houses, for parts, only sell to contractors.

Typically the best thing to do is call a local heating contractor to troubleshoot and repair.

My idea? Call a qualified HVAC technician for evaluation & repair.
