A working furnace is more than just a comfort during colder months. It’s a necessity for homes in Puyallup once temperatures begin to drop. But sometimes, without warning, the furnace won’t start or takes way too long to kick on. Often this connects back to the ignition system. It doesn’t take long for that small issue to grow into a bigger problem if it keeps happening. A faulty ignition system can delay heat, waste energy, and even put parts of your system at risk.
If your furnace has a habit of clicking but not lighting, or starting and then shutting off shortly after, ignition trouble might be the reason. These types of problems don’t always lead to complete breakdowns right away, but they never fix themselves either. Homeowners in Puyallup dealing with ignition problems often notice them first during colder mornings when the furnace should be running but the house still feels cold.
Common Ignition Issues in Furnaces
Furnace ignition systems need to fire up smoothly and safely each time your thermostat calls for heat. When this system fails or slows down, the rest of the unit won’t work properly. Below are some of the most common sources of ignition trouble:
1. Dirty or Clogged Ignition Components
Over time, dust and debris naturally collect on parts inside the furnace. Pilot lights and flame sensors need to be clean to operate well. If the flame sensor has buildup or corrosion, it may stop recognizing that the flame is lit. This causes the system to shut down for safety. Even minor grime on the igniter can cause the furnace to keep trying without success.
2. Faulty Ignition Control
Modern furnaces often rely on electronic ignition. The ignition control board makes decisions about when to start gas flow and fire up the flame. If this electronic control fails, the system might not light properly or may not light at all. Electrical wear, surges, or loose wiring connections can all throw this control off.
3. Problems with the Gas Supply
If gas isn’t flowing consistently to the ignition components, the furnace can’t light. This could happen due to faulty gas valves, blockages, or pressure issues. Even changes in line connection or small valve failures can keep proper ignition from happening, forcing the system to reset over and over.
Here’s a quick summary of signs pointing to furnace ignition issues:
– Your furnace clicks repeatedly but doesn’t ignite
– It starts to run but blows cold air before shutting off
– It delays every time before turning on after you adjust the thermostat
– You notice a smell of gas without the unit fully operating
At first, these situations may seem minor. But over time, they can place stress on your furnace by forcing it into repeat starts, which uses more energy and adds wear on parts.
Warning Signs of Ignition Problems
Early signs of ignition problems can easily get mistaken for other issues like low airflow or weak heating. But catching these symptoms early could help avoid larger repairs. If you notice your furnace isn’t firing up the way it used to, take note of consistency and timing.
Look out for:
– Unusual startup noises, such as repeated clicking or small bangs, that don’t stop right away
– Delayed ignition, where the blower starts running before the flame kicks in
– A furnace that shuts off a few seconds after starting
– Constant resets required to get heat
– The smell of unburned gas in the area around the furnace
For example, if you hear loud clicking every time the unit tries to start but don’t feel any warm air, it may be cycling through failed ignition attempts. This problem doesn’t go away with time. It only becomes more unpredictable. Being aware of how often it’s happening is helpful for a technician tracking down the exact part that’s causing the issue.
In some newer models, control boards may show error codes or blinking lights that help confirm ignition failure. Still, whether your furnace is older or newer, consistent ignition trouble means it’s time to have it looked at by our professionals before a small fix turns into full system damage.
Preventive Measures and Maintenance Tips
One of the best ways to keep furnace ignition problems from showing up is to have a regular maintenance routine. Many issues, like dirty components or loose wires, are easy to prevent when they’re caught early. A clean system doesn’t just run better. It also avoids the strain that builds up when parts have to work harder than normal.
Here are a few ways homeowners in Puyallup can reduce the chances of dealing with ignition troubles:
– Stick to an inspection schedule: Having the system looked at each year by trained technicians helps catch wear and tear before it affects performance
– Clean components regularly: Igniters, burners, and flame sensors need to be free of buildup to work correctly. Dust and debris are common, especially if the furnace is in a drafty or semi-finished area like a garage or basement
– Address small issues early: If you notice slow starts, short runs, or strange smells, don’t wait. These minor issues can put stress on ignition parts, and quiet warning signs tend to grow louder with time
– Check airflow and filters: While this may not directly cause ignition problems, clogged filters can lead to overheating, which may trigger safety systems and cause shutdowns
– Verify gas flow and settings: Valves and pressure settings must stay consistent throughout the year. If something cuts off flow or changes the pressure, your system may fail to ignite properly
Even simple maintenance goes a long way in preventing future repair calls. For example, a dirty flame sensor that’s cleaned once a year can keep a furnace from shutting down repeatedly through the winter.
When to Call Our Professionals
If your furnace continues acting up after a filter change or reset, it likely means something deeper is going on. Ignition systems involve electronic components, fuel lines, safety sensors, and controls. These parts are not just difficult to access. They can also pose safety risks if handled without proper knowledge and equipment.
Call our professionals if:
– You hear repeated clicking without ignition more than once a day
– The furnace starts but turns off within seconds every time
– There’s a noticeable burning smell or gas odor during startup
– Parts look visibly burned, cracked, or corroded upon a visual check
– Resetting the furnace works only temporarily and the issue returns regularly
These are signs that the system isn’t just dirty or slightly out of tune. Instead, there may be broken ignition components or gas flow issues that need expert adjustment. Delaying repairs here can shorten the system’s lifespan or drive up heating bills with constant restarts.
Our technicians have the training and tools to diagnose the specific point of failure and correct it safely. That way, you avoid guesswork and the risk of damaging other parts of the furnace during trial and error.
Keep Your Heating System Strong This Winter in Puyallup
Furnace ignition problems are rarely random. When one symptom appears, others usually follow—and faster than most homeowners expect. Whether it starts with a small delay or ends with total failure to heat, ignition issues need to be addressed quickly. Waiting leads to more wear on internal parts, and sometimes even a complete shutdown at the worst time.
Staying alert to early signs and investing in regular maintenance keeps your system stronger through the colder months. In Puyallup, a reliable furnace isn’t just about warmth. It’s peace of mind. If your heating feels off, or if the system just isn’t starting the way it used to, it’s time to act before things get worse.
