How do I know if my furnace ignitor is bad?
Your furnace won’t run: The most obvious sign that your ignitor is bad is that it won’t ignite, and this generally manifests itself in your furnace failing to run when you activate it. One word of caution, though: this can also be caused by other issues, some of which are electrical.
What does a bad igniter look like?
A No Glow Ignitor When the furnace kicks on, the ignitor should glow. The ignitor needs to get super-hot so that it ignites the gas/air mixture needed for combustion. Look under the furnace for the glow! If you don’t see it, you likely have a bad ignitor.
What causes a furnace ignitor to fail?
As mentioned above, sometimes the cause of a furnace ignitor failing to ignite is due to a safety issue, such as a clogged air filter, for instance. So, if your furnace is failing to ignite, it’s a good idea to check the air filter. If it looks clogged up, then this is probably the source of the problem.
Can a furnace ignitor go bad?
Don’t worry—an ignitor that goes bad is common for most furnaces. Fortunately, you can replace the ignitor without replacing the full furnace. Most ignitors last about seven years.
Can hear your furnace click on but it does not fire up?
The Pilot Light (Faulty Ignition Sensor) The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. This is typically the problem if you can hear your furnace click on but it does not fire up. If the sensor or ignitor is dirty, it will need to be cleaned.
How much does it cost to replace furnace ignitor?
Here’s the bottom line: Whether for a natural gas furnace, oil, or a propane furnace, replacing a furnace ignitor–including parts and labor–will cost you around $300 – $425 for a qualified contractor to install. Compare that to, say, a draft inducer motor, which will cost $400 – $1,500 to replace.
Are furnace ignitors universal?
This universal ignitor is a replacement part for use in gas-fired appliances like furnaces, water heaters, and boilers, compatible with over 150-OEM models.
Are furnace ignitors interchangeable?
Most ignitors are interchangeable as long as they fit in the furnace space provided. Select your ignitor by looking at the one you have, and comparing it to the photos of ignitors here; select the one most similar.
How often do furnace ignitors fail?
According to the Gas Furnace Guide, ignitors have an average lifespan of four to seven years. So, after about seven years, you may have to replace the ignitor; however, you probably won’t have to replace the entire furnace because other parts, such as the heat exchanger, can last more than 15 years.
What causes an igniter to stop working?
A simple issue could be that the limit switch is not working correctly or alternatively the air filters on the furnace could be clogged up. Clogged filters can cause the limit switch to turn the ignitor off prematurely.
Can you clean gas furnace ignitor?
Try Cleaning the Ignitor With Compressed Air If your furnace has a spark ignitor and it’s working haphazardly, it too could be covered with soot, and a blast of compressed air may be enough to clean it. Compressed air can also clean a blocked pilot tube that is causing the pilot flame to burn weakly or not at all.
Can you clean an igniter?
Use the toothbrush and a paste of baking soda and water or a 50/50 vinegar solution to clean the surface of the igniter. Avoid cleaners with bleach, ammonia or any other chemical that could produce noxious fumes. If you have to chip material off it, use a plastic toothpick or kitchen knife.
Why is my gas heater not igniting?
One of the most common reasons for your gas heater not igniting or stopped working is because its thermostat is either off or not working properly. Therefore, make sure you check the thermostat, and if it is off, then turn it on while setting it on heat mode (5 degrees above your room temperature, at least).
What does it mean when your furnace makes a clicking noise?
Your furnace is most likely making a clicking noise due to your furnace’s spark igniter trying to ignite the pilot light/burners. A repeated clicking indicates a failure/system malfunction. This problem is especially troublesome when you are not getting heat at some point during the very cold winter months.
Why does my furnace Keep clicking on and off?
The thermocouple is likely reacting to an abnormal flame temperature and shutting off the gas automatically. This is why the clicking sound continues. If you furnace begins clicking and the blower turns on and off again, this may indicate a faulty flame sensor.
Is it hard to replace a furnace ignitor?
Thankfully, most heating, air conditioning, and ventilation companies sell igniters for most furnace models, including those no longer manufactured. Qualified Technician: Most homeowners will agree that furnace tune-up and replacing an igniter is relatively easy.
