Welcome! Here are some tips for using this forum.
Last week my oil-fired home furnace "died." I called a local shop with a great reputation and a very
experienced technician showed 2 hours later. He immediately diagnosed the problem as the ignitor (Carlin model 41000), popped in a new one (same model), fired up the furnace, did a thorough tune-up and left. He said this particular model ignitor is prone to failure in 5-7 years. Is that true? And if it is, is there a replacement from another maker that might last longer? (But at age 84 maybe I shouldn't worry about furnace longevity.)
