How To Know If Your Furnace Ignitor Is Bad?

If you have a gas furnace, you rely on an ignitor to light the burner. Without a functioning ignitor, your furnace won’t heat your home. If your furnace is having trouble igniting, there are a few things you can check before you call a technician.

First, check the ignitor itself. If it’s cracked or damaged, it will need to be replaced. If the ignitor looks good, the problem may be with the gas valve.

Make sure the valve is open all the way. If it’s not, turn it clockwise until it stops. If the valve is already open, the problem may be with the pilot light.

• Inspect the ignitor for any cracks or damage
• Check the ignitor wire for any signs of wear or fraying
• Check the ignitor electrode for any build-up of dirt or debris
• Test the ignitor with a multimeter to see if it is producing a spark
• If the ignitor is not producing a spark, replace it with a new one
