THIS IS A GUIDE AND CANNOT PROVIDE ALL DETAILS FOR EVERY SITUATION. There is also detailed written replacement instructions & another video if you scroll down to the bottom of page Introduction The most common types of furnace are the gas furnaces. The more modern gas furnaces do not have hand-lit burners anymore. Standard hot surface ignitors need replacement about every 3-5 years under normal conditions, although the silicon nitride kind do last a couple years longer. It's a good idea to always have a spare or two waiting so that they can be switched out when necessary.

DO NOT TOUCH THE CERAMIC PART OF THE HOT SURFACE IGNITOR!! In fact, don't even bump the ceramic part of the ignitor against anything. If it gets even a hairline crack it will fracture and not work! Use the right tools for the job. Pay attention to what your doing! If unsure, call a professional. Verify The Ignitor Is The Problem Before Proceeding To Next Step Before proceeding with the ignitor replacement, you should verify that it is the cause of the problem. On spark ignition systems, it is rare for the ignitor or flame sensor to go bad. They are really just a piece of metal with a ceramic insulation mounting base. If they appear to be bad, look for a crack in the ceramic base. If you do not see a crack the ignitor or sensor is probably not defective. Sometimes they get a buildup of deposits on them which cause them not to sense the flame. Instead of replacing it, you should clean the sensor by wiping the deposits off or shining with a piece of steel wool. On hot surface ignition systems, if the ignitor does not heat up and glow bright orange, look for a crack in the ignitor. It is usually easy to spot. If there is not a crack, the ignitor is good. How To Change The Hot Surface Ignitor On Your Furnace DIFFICULTY LEVEL: Moderately easy Things You'll Need: Flashlight Socket wrench with 1/4" socket Also see this great step by step video to see how to replace your gas furnace ignitor STEP 1 Turn off the power to your furnace at the electrical breaker box. STEP 2 Take off the front panels of your furnace. To get to the hot surface ignitor you have to take off the top panel first. In the Trane XE80, this panel covers the blinking lights that tell you if your furnace is working properly. STEP 3 Now remove the bottom panel that covers the motor and the hot surface ignitor. It also holds the gas valve. Just to be safe, go ahead and turn off the gas valve. IF YOU SMELL GAS AROUND YOUR FURNACE, STOP RIGHT HERE AND DON'T CONTINUE UNTIL YOU'VE HAD YOUR FURNACE CHECKED BY YOUR GAS COMPANY. STEP 4 Locate the hot surface ignitor. It is close to what looks like a back wall inside the furnace; you can see the plastic plugs here where it was plugged into the electrical wiring for the furnace. STEP 5 Go ahead and unplug this part STEP 6 Now locate where the ignitor is actually inserted; notice the single screw that is holding it in place against a bracket. STEP 7 Using the proper tool for the job, which in this case is a 1/4 inch socket, remove the screw and pull out the hot surface ignitor STEP 8 To find a replacement hot surface ignitor shop online (this will save you tons of money!) You can go online and compare your hot surface ignitor to the photos provided and pick the one that matches. This easy chart can also assist you in proper selection. You can also contact a supplier with the Model # of your ignitor and have them tell you precisely which part you need. STEP 9 Look at your burned out hot surface ignitor - note the ceramic end that actually turns red hot inside your furnace. NEVER TOUCH THIS!! When you get your replacement part, use gloves if you have to, but DO NOT TOUCH THE CERAMIC PART OF YOUR IGNITOR! The oil on your hands will ruin the ignitor and it will blow up again in just a few days after installation. I can't emphasize this enough. STEP 10 Insert the hot surface ignitor, put the screw back in and gently tighten. Plug in the plastic end to the furnace electrical wiring. Replace your furnace panels. Following the instructions on your furnace, proceed to start it up again. (I turn my thermostat all the way down, turn the gas valve on, turn the breaker switch back to ON, then turn my thermostat to the temp I want and voila' - it works!
