The Parts that Fail Most in Furnaces (and Why)
When you pull back the cover of your furnace it may look like there’s a lot going on, and there is. The good news is of all those parts, there are only about a dozen components that go into making your furnace work. But, they are all absolutely essential. While most components do their part in producing and distributing heat, others are solely dedicated to the safety of your family and home. While it may be a hassle to call in a technician, there’s often a good reason why your furnace has shut down and you should have a professional take a look before tinkering yourself. Before you call out a furnace repair technician, be sure to check that your gas service is on and/or that your propane tank has adequate pressure.
So what components of your furnace fail the most and why? Read on to find out:
1) The Ignitor — When you look into a properly functioning furnace, the ignitor is the part that glows red as electricity passes through it to heat up the metal. The constant heating and cooling of this part makes it one of the most common parts we replace. An ignitor can easily short out due to debris, dirt, and even insect interference. Or, it can also be something as simple as the ignitor reaching its functional lifespan after years of countless on/off cycles.
2) Pilot Light — While the part itself may not fail since it has no moving parts, pilot lights will eventually become clogged with ash and soot if regular maintenance is not performed. Save yourself the chill of winter and the cost of an unnecessary repair by scheduling regular maintenance on your gas furnace.
3) Power Vent Motor — Power vent motors often fail since they are subjected to high temperatures radiating from the flue gas. While all furnaces have the same aim — to heat your home — some furnaces are simply not up to par with today’s manufacturing practices. Before you purchase a new furnace, we would be more than happy to recommend a unit that is designed to last.
