I hired a heating and air company to do a service on a furnace in one of my rental units in Reno. His diagnoses was that the furnace is in good condition but that the igniter was showing signs of age. My experience with igniters, although limited, is either they ignite or they don’t. Am I wrong? Can a technician tell by checking ohms? Should I just replace the igniter? So many questions.
