Does a continuously running furnace pilot light need a spark igniter? It does not “NEED” one as the pilot light can also be lit with match or a lighter but it is more convenient to use the igniter. The igniter is only needed if the pilot goes out and needs to be re-lit.

Should the pilot light always be on in a gas furnace?

Should The Pilot Light Always Be On In A Gas Furnace? Yes, if the furnace is in operation, the pilot light will need to be on for it to be functional. However, some homeowners turn off their furnace’s pilot light in the warmer seasons when the gas furnaces aren’t in use.

What is intermittent pilot ignition?





Intermittent Pilot Ignition is an electronic system, which uses an electrode to ignite the pilot gas. In turn, the pilot flame lights the main burner gas. The term Intermittent is used because the pilot burner flame is only present when the main burner is operating.

Can you manually light a gas furnace with electronic ignition?

If your furnace is equipped with an electronic igniter, you cannot light the furnace manually. However, you may be able to get the furnace working by turning off the igniter and resetting it. Find the paperwork for your particular furnace to locate the reset button or switch.

What causes ignition failure on a furnace?

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. Air filters should be changed on a regular basis, to prevent these kinds of problems. However, a lot of furnace owners fail to do this.

What is the difference between direct spark ignition and intermittent spark ignition?

First off lets handle direct spark ignition. There is NO pilot light on this systeml. The spark ignition is directed to the main burner. Now there is a condition known as “intermittant sparking” that refers to the spark continueing to fire after the furnace (or stove) is lit.

What is continuous pilot?





CPI – Continuous Pilot Ignition, means your pilot light stays on constantly, even hen the fireplace main flame is not on. IPI – Intermittent Pilot Ignition, means your pilot is lit only on demand to ignite the main burner, right after you turn the fireplace on.

Quote from Youtube video: Itself now use a probe to touch one of the igniters terminals and the second probe to touch the other terminal. If the meter reading shows a result between 50 and 400 ohms of resistance.

How much does it cost to replace an igniter on a furnace?



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.

Can a furnace ignitor be cleaned?

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.

How do I clean my furnace ignitor sensor?

If your furnace reset button keeps tripping, it’s likely that your furnace is overheating. This may indicate a need for furnace repair services.

Is a flame sensor and thermocouple the same thing?

A thermocouple is a safety device that is used on gas furnaces where the pilot is lit continuously, whether the main burner is on or off. The flame rectification sensor is a safety device used in high efficiency furnaces that use direct burner ignition.

Is flame sensor same as Ignitor?

A flame sensor is a crucial safety component on your gas heating system. During the ignition cycle, your gas furnace goes through a process where a spark or a hot surface ignitor will actually ignite the gas. As the gas is ignited, the flame sensor creates a current of electricity.

How do you reset the flame sensor on a furnace?
