Is it possible for an ignitor on a home furnace to run too hot? I had a heating and air company come out to do an inspection on a rental unit so I can renew the certificate of compliance. It has been renewed now but I was also told the ignitor was running too hot and should be replaced before winter otherwise the renters could be, "Dead in the water and without heat." That was several months ago. Since I don't know a whole lot of information about furnaces I tried looking that problem up and found nothing. After talking to someone who was more knowledgeable about heating and air than I am it now sounds like they might not be so trustworthy and were looking for some extra $$$. Either an ignitor works or it doesn't right? Maybe someone here can give me a second opinion. Furnace is around 20 years old and natural gas. Space that is heated is around 1250 sq ft. Thanks!
