When working properly, the igniter draws hot air from the convection blower through the igniter housing and over the hot igniter probe to light the pellets.
If the igniter probe heats up in the stove but fails to ignite the pellets, air flow in the firebox may be restricted. When pellets do not ignite, make sure that the air inlet holes on the igniter tube are not blocked by ash or sealant. If the problem continues, thoroughly clean the stove and remove ash build-up from the burn grate, heat exchangers, ash pan, air passages and exhaust venting. A pressure difference of -0.02 or higher between the upper firebox & the lower ash pan area is required for proper stove function and ignition. If the heat does not reach the pellets, they cannot ignite. Once the stove has been thoroughly cleaned, uninstall and clean the combustion blower including the impeller as well as the combustion blower housing. We also suggest bench testing the blower outside of the stove by connecting to wall power. As soon as the motor is connected to power the impeller should start up right away and spin very fast. If the combustion blower runs slowly, it is not creating proper air flow in the stove and it should be replaced.
If the igniter does not heat up in the stove check the probe connections to the timer. Inspect the inline 6-amp fuse and replace if it is blown. Ensure that the pigtail is properly connected between the wire harness and control board. If there is no change, bench test the igniter outside of the stove. Be sure to place the igniter on a non-combustible surface, then connect the igniter to 120 volts from a standard socket. When connected directly to wall power the probe should glow cherry red.
