The air fiter was replaced recently. The old filter was not very dirty. This condo & furnace are only six (6) months old.
How do I indentify these parts - then - I look for an adjustable setting?
Might look like this one
I've removed a couple of panels exposing the electronics - and I don't see any components like the one in the PDF.
There's a nickle sized component located near the gas burner area. Two wires connect to it. Could this part be defective causing the burner to shut down too early? I guess I'm at the point of calling the repair person.
