Signs Your Furnace Ignitor Is Faulty
The furnace ignitor is one of the most important parts of your furnace. It is a small ceramic rod that uses an electrical current to create heat. This heat is then used to ignite the gas in the burner assembly and start the flow of hot air.
Over time, ignitors can wear out and become less effective. Precise Air Systems, Inc. provides quality furnace repair in Glendale, CA. Contact us today at (818) 240-1737.
If your furnace ignitor is faulty, it can be difficult to tell. Some signs that your furnace ignitor may be losing efficiency include the following:
- The ignitor glows, but the burner doesn’t light: If you can see the ignitor glowing but the burner doesn’t light, that’s a sign that the ignitor is faulty. Additionally, a faulty wire or connection usually causes this problem.
- The ignitor glows for a long time before the burner lights: If it takes longer than usual for the burner to light after the ignitor glows, that could be a sign that the ignitor is going bad. Ignitors typically only need to glow for a second before the gas ignites.
- The furnace produces a strange sound: If your furnace starts making strange sounds like popping, clicking, or buzzing, it could signal that the ignitor is faulty. If you hear these sounds, turn off the furnace and contact our professionals for furnace repair in Glendale, CA.
- The furnace doesn’t produce enough heat: If your furnace isn’t heating your home as well as it used to, it could be a sign that the ignitor is faulty. A bad ignitor can prevent the burner from igniting properly, reducing the heat produced by the furnace.
- The furnace turns on and off frequently: It may indicate a damaged ignitor if your furnace starts and stops more frequently than usual. A faulty ignitor can cause the furnace to cycle more often because the burner isn’t igniting properly.
If you notice any of these issues, call our professional HVAC contractors at Precise Air Systems, Inc. for furnace repair in Glendale, CA. We can help you diagnose the problem and get your furnace back up and running quickly.
Furnace Ignitor Testing And Replacement
If your furnace is having trouble igniting, it may be time to test or replace your furnace ignitor. Testing the ignitor is a simple process that can be done with a multimeter. Simply set the multimeter settings to the ohms and connect the probes to the two ignitor wires. If the ignitor works properly, you should see a reading between 4 and 10 ohms. If you don’t see a reading or the reading is infinite, the ignitor is likely faulty and needs to be replaced.
Replacing a furnace ignitor is a relatively simple process that can be done in an hour or less:
- Turn off the power to the furnace, remove the access panel, and locate the ignitor. Once you’ve found the ignitor, disconnect the wires and remove the mounting screws.
- Install the new ignitor in the same position as the old one and reconnect the wires.
- Replace the access panel and turn on the power to the furnace.
