What to Do If Your Furnace Won’t Ignite

Posted on

Nothing’s quite as frustrating as coming home to find your home cold, even though you had your furnace switched on. When you’ve checked the system and found that the furnace isn’t igniting, you are left wondering what to do.

While you are always welcome to contact the Air Professionals team for help, you may be able to fix this one on your own. Here are some common reasons for a furnace to not ignite!

What Causes a Furnace to Not Ignite?

If your furnace won’t ignite, it could be due to a number of concerns. Some of these include:

  • Problems with the thermostatIs the thermostat set properly? Does the thermostat have an error code or need a fresh battery? These problems can be the underlying cause, and are easy to fix.
  • Problems with the gas line If the gas line is not sending gas to the furnace, it won’t ignite. Check the shut off valve located outside your home. You can also test by turning on your gas range to see if it turns on.
  • Problems with the furnace Your furnace should have a switch that turns it on and off. Make sure it’s set to “on.” Check the gas valve, pilot light and circuit breaker for problems. If you’ve tripped the breaker, only try resetting it once, as continual problems mean an electrical issue that needs to be addressed by a pro.

Each of these you can check on your own and, if you find the problem, handle the fix without help.

Signs Your Furnace Igniter Needs to Be Repaired or Replaced

If your furnace has an igniter, then you’re in luck. The signs of igniter problems are fairly easy to spot. If you’re noticing one of these signs of igniter failure, give Air Professionals a call.

  • You had a power outage, and now your furnace won’t work. A power outage can damage the electrical components in your home’s appliances, including your igniter. If you had a power outage, and now the furnace won’t respond, then the igniter was probably burned out in the surges that caused the power outage.
  • The furnace turns off before properly heating the home. If the furnace seems like it’s working as it should, but then kicks out before the home is heated, then it’s probably a problem with the limit switch. If the limit switch, which monitors the internal temperature of the furnace, isn’t working, it will prevent the igniter from responding. While not technically a problem with the igniter, this still requires attention.
  • The furnace dies suddenly. If you’re using your furnace and it suddenly dies and refuses to start back up again, then the igniter is probably the culprit. The igniter isn’t going to last as long as the furnace, and replacement is typically necessary every few years.
