The igniter glows red and then lights the burners in the gas furnace. Over time, the igniter is continually getting red hot and then cooling, creating stress on the element. Because of this, igniters have a 3-5 year life expectancy. They will eventually crack and need to be replaced.
Age and wear: Ignitors typically last three to five years before needing replacement. Physical damage: Cracks or breaks in the ignitor can occur during maintenance or because of debris. Electrical issues: Voltage problems or wiring faults can damage the ignitor.
A gas oven igniter replacement costs $150 to $325 on average, depending on the brand and model. A new oven igniter costs $20 to $50 for the part alone. A broken igniter results in the oven not heating, clicking noises without lighting the gas, and gas leaks.
How Often Should a Furnace Ignitor Be Replaced? On average, furnace ignitors will last about four to seven years. This depends upon how well maintained the system is. After the seven-year mark, you should replace it.
Whether it's grease buildup or food crumbs, one of the most common causes for a gas burner that has trouble igniting is debris blocking gas flow to the igniter. The fix: Begin by removing the grate covering the troubled burner. Next, remove the burner cap, which should lift off with ease.
Introduction. Have you noticed your gas oven is taking too long to heat up, or it no longer heats at all? There's a 95 percent chance you just need to replace a $25 igniter. Gas oven igniters last around eight years.
The Short Answer Is: Warning signs of a bad furnace ignitor include the furnace not starting or heating, a noticeable clicking sound without ignition, or frequent short cycling where the furnace turns on and off rapidly. Additionally, if the ignitor appears cracked or discolored, it may need replacement.
A furnace ignitor replacement costs $100 to $250 on average. Most universal hot-surface ignitor prices are $15 to $35 for the part alone. Gas furnace ignitor prices are $20 to $100 for parts from the original manufacturer (OEM). The labor cost to replace a heater ignitor is $80 to $200.
Can you DIY a furnace ignitor replacement? In short, yes, you can DIY a hot-surface ignitor replacement. It shouldn't be too difficult if you have experience fixing things around the house. However, if you typically feel clueless about troubleshooting household appliances, this may not be the right job for you.
Inspect the pilot hole and use a wooden toothpick to clean it out. If the buildup is excessive and cannot be removed, you will need to replace the igniter to restore your gas oven. Once you are done cleaning, turn on the oven and observe the igniter to see if it glows red-hot during the ignition process.
The cost of a furnace ignitor can range from $20 to $100 for the part itself, depending on the type of ignitor and whether the replacement part is universal or from the original equipment manufacturer (OEM).
If you see any gaps, bends, or other mishap that makes the burner cap not fit snuggly on top, then that might be the reason your stove keeps clicking. A misshaped burner cap needs to be replaced as the clicking sound you hear could be the gas stove's igniter constantly trying to spark, even when it's turned off.
Remove the ignitor carefully by holding only the base. Avoid touching the ignitor surface with bare hands. Use compressed air to remove carbon deposits. Gently wipe the surface with a soft cloth or scuff pad until shiny.
The Average Furnace Lifespan
A well-maintained furnace can last at least 15 to 20 years, but completing annual maintenance and being diligent with repairs can extend its life even longer.
Here are some of the most common reasons why the ignitor fails. Using The Wrong Ignitor: Ignition failure will happen if your furnace uses an ignitor that has the incorrect voltage. The Limit Switch Becomes Too Hot: Furnaces have a built-in limit switch that detects high temperatures and prevents overheating.
Because of this, igniters have a 3-5 year life expectancy. They will eventually crack and need to be replaced. If you suspect that you have a damaged HSI, you will most likely be able to change the part yourself. Like a light bulb, they are a regular replacement item.
The Furnace Doesn't Blow Hot Air.
The furnace ignitor is the light switch in the heating process. Without it, the pilot light cannot recondition air intake. No fire transforms air into heat, resulting in cold air distribution.
Pilot Lights and Flame Sensors Could Be the Issue
A modern furnace without a pilot light relies on flame detectors to ensure the successful completion of a heating cycle. If the flame detector is covered in dust, dirt, or grime, you will quickly lose heat and your gas furnace will start blowing cold air.
A spark igniter electrode is made of metal and the base of the igniter is ceramic. This ceramic base can withstand the high temperatures put out by the burners. The ceramic is fragile and over time may crack or may have other damages and it may be shorting to ground and unable to ignite the gas flame.
Today's furnaces rely on electronic ignitors. These systems can be divided into two groups: pilot systems that are intermittent or ignition systems that rely on a hot surface. A spark in the intermittent pilot system turns on the pilot light, as opposed to the old pilot light that burned continually.
However, as so much rests on this little igniter, they are prone to a bit of wear and tear. If you find your gas oven igniter is not working, you should first try to troubleshoot the issue and double check it is your oven igniter that's not working.
The national average for gas stove repairs ranges from $150 to $400. Most homeowners pay $200 for replacing a gas stove igniter. Some repairs are cheaper or expensive, depending on the problem, part costs, and labor.
