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 identify these parts - then - I look for an adjustable setting?
Should be small little control with silver cover maybe 2 x 3" has dial inside with three pins attached to there temperature settings lowest is fan off next is fan on and the highest is high limit.
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.
