On a repair call, a contractor working a Tillamook County boiler goes straight to the burner assembly and ignition system, because those are the parts that have been cycling hardest. Homes in Tillamook County, OR run heat about ten months a year, from September through June. That kind of continuous seasonal demand builds wear on the igniter, the burner orifices, and the heat exchanger at a pace that shows up long before the boiler fails outright. Cracks in the heat exchanger or a degraded igniter rarely announce themselves; a contractor finds them by opening the unit and looking.
Boilers in houses old enough to have seen multiple heating systems come and go accumulate a specific problem: the components that fail are often from a generation the supply chain has largely moved past. Half the homes in Tillamook County, Oregon were built in 1980 or earlier (2020-2024 ACS 5-year). A contractor opening a boiler here may find a heat exchanger or a zone valve that is still functional by the manufacturer's original spec but has no current equivalent on the shelf. That parts search, not the labor, is what stretches a repair and changes what gets quoted.
The Parts of a Boiler a Contractor Checks First
The boiler itself sits in the basement or utility room and is where water gets heated. A faulty heat exchanger inside it can cause the whole system to underperform or shut down on a safety lockout. The burner assembly, also inside the unit, is a common point of failure when a boiler stops firing or fires unevenly.
The circulator pump moves heated water out through the pipes and back again. When it fails, rooms go cold even though the boiler runs fine. The expansion tank, usually mounted nearby on the supply line, absorbs pressure changes in the system, and a waterlogged or failed one drives pressure readings outside the range the boiler will tolerate.
The drawing shows a representative layout, and a licensed contractor determines which components apply to the specific system in your home.
