While some furnaces can last over 40 years (extremely rare), the average lifespan of a typical gas furnace is around 15-30 years. As long as you have scheduled yearly furnace maintenance, your furnace should easily last over 15 years.

How do I know if my hot surface ignitor is bad?

Set the multimeter so it can properly measure a resistance of 10 to 200 ohms. Disconnect the hot surface ignitor from the control board and measure the resistance. A good hot surface ignitor will have a resistance of 40 to 90 ohms. Greater than 90 ohms indicates a failing or failed hot surface ignitor.

What does a furnace ignitor look like?

Some burner assemblies may hold a flame sensor as well. The spark ignitor looks like a 1-inch long metal probe attached to one end of a solid ceramic tube with an electrical wire attached to the other end of the tube.

What causes ignition failure on a furnace?

A gas furnace burns a mixture of air and natural or LP gas. Often times the reason air does not get to your furnace's igniter is because it is restricted. The main reason for this air restriction is usually traced back to dirty air filters. So check them if your gas furnace fails to ignite when you turn the system on.

What is an ignitor on a furnace?

The hot surface ignitor is a device used in most modern furnaces to ignite the gas you use for heat. It's a relatively simple component that works quite like a toaster in that its heat is generated by forcing 120 volts through an exposed, resistant material.

How does a spark igniter work on a furnace?

Newer gas furnaces are equipped with an electric ignitor to light the furnace and turn the fuel into heat that then warms your home. The ignitor sparks and lights the burner which opens the gas valve to initiate a combustion process that creates heat.

How do you clean the flame sensor on a Rheem furnace?

How to Clean the Flame Sensor on Rheem Heaters
  1. Turn off the power supply to your heater at the breaker box.
  2. Remove the lower front panel from the heater to access the burners.
  3. Pull out the flame sensor once you locate it.
  4. Wipe the surface of the flame sensor down with 400-grit sandpaper.
  5. Reinstall the flame sensor reversing the steps you took to remove it.

How do you check direct spark ignitor?

Insure the multimeter is set for AC milliamps and turn on the test power cord switch to power the ignitor. If there is no spark, replace the ignitor. Monitor the input current with the multimeter set on AC milliamps for 5 minutes. If at any time the reading drops below 300 milliamps AC, the ignitor should be replaced.

How do you ignite a Rheem furnace?

Once the gas has had time to dissipate, turn the knob to "Pilot." Then, hold down the "Reset" button and bring the flame of a long lighter close to the pilot light opening. This should light the furnace pilot light. Once you are sure the pilot light is on, release your pressure on the reset button.

Does Home Depot sell furnace ignitors?

What causes furnace ignitor failure?

ignitor failure. Call your electric company if you are getting high voltage in your home. Debris from the heat exchanger or bugs/spiders can get on the ignitor while the furnace is not calling for heat and when there is a call for heat the debris/bug can short the ignitor out.

How do you light a gas furnace with electronic ignition?

The pilot light has a separate small gas line running to it with its own valve. When the furnace comes on, this valve opens, and then the electric spark ignites the pilot. A flame sensor detects that the pilot is lit, opens the valve to the burners, and the pilot light ignites the burners.
