Assembly Instructions For Whitfield & Lennox Igniter With Fuse, H8127

Replacing the H8127, H8127-AMP igniter in a Whitfield or Lennox/ IronStrike Montage pellet stove:

  • Unplug the stove
  • Remove the rear service panel
  • Remove the auger motor from the shaft and remove auger mounting plate
  • On some models and the tools you may be using, the igniter can also be accessed from the left side by removing the room blower
  • Locate the igniter under the hopper, it will have white braided wires
  • Disconnect wires from old igniter and remove the igniter from the stove
  • using a 5/8" wrench, loosen igniter fitting by turning it CCW
  • There will be a red wire with a black cap attached to the igniter wires, this is an inline fuse and must be checked. If the fuse is blown, replace it.
  • Reinstall all items in the reverse order.


Replacing the H8127, H8127-AMP igniter in a Whitfield or Lennox/ IronStrike Montage pellet stove:

  • Sometimes the igniter fitting can be very difficult to crack loose, if this is the case, cut the old igniter wires as close to the fitting as possible and use a 5/8" deep-well socket and a breaker bar to crack the fitting loose
  • Always insert the new igniter and hand tighten it by hand to avoid crossing the threads
  • Stoves equipped with an igniter, especially older Whitfields, must have an igniter present in the igniter tube when the stove is operating. If you decide to use the stove without auto ignition for whatever reason, do no operate the stove without an ignition cartridge in the igniter tube, it will not burn properly

It is advisable to ALWAYS replace your door gasket when you are replacing an igniter. A leaking door gasket is often a contributing factor to igniter failure.

Troubleshooting Igniters:

Igniter failure can be verified on one of three ways. The easiest and most common way to see if the igniter is working is to start your stove or grill and visually look for the orange glow; however, some appliances do not have a visual way to do this, so you may have to physically feel around in the burn pot after the stove has been on for a few minutes to “feel” for heat being generated. If you can see the glow or can feel the heat from the igniter, chances are that the igniter is actually working. If this is the case, retry the startup process. Make sure your burn pot is seated correctly if it is removable. Make sure that your ash pan, door or hopper lid is closed as this will provide an airtight seal on the stove, which most igniters will require for proper ignition. If you still do not have any luck, give the stove a good cleaning, including the vent, and try again. If these attempts fail, further troubleshooting will be required, which leads us to the third method.

For this method, you will need a DMM (Digital Multi-Meter). Gain access to the igniter and remove it from the stove or insert. While you are taking the igniter out, verify that it is installed correctly with the correct mounting equipment, screws, etc.. With the igniter removed from the stove, you will need to look over the part to find the rated watts, it’s usually stamped on the metal somewhere. If you cannot find it, look on our website for the correct igniter; the information you are looking for will be under “technical specs”

If your Ohms reading is within 10%, more or less than the rating (46Ω +/- 10%), it’s good. If the igniter has a “contained short” or a short within itself and not grounding out, your Ohms reading will be very low...usually in the single digits. Generally, you cannot have a faulty igniter with too high of a resistance reading unless an igniter is installed that is way out of spec. An example of this would be your stove requires a 300W igniter but the stove has a 250W igniter installed. The reading in this scenario would be 52Ω. The reading would be correct to the igniter but would be the wrong value for the specified 300W igniter. That’s why it’s usually good to look at the part itself for the watts rating.
