Our stove stopped igniting in auto mode today. We've had it for almost five years now and this is the first issue we have had, so I guess we are lucky. I checked the burn pot, cleaned out any ash, etc.... Blower is operating. How hard is it to change out the igniter on this stove? When replacing the igniter how do you pull the excess wire out through the back so they are not in the burn pot per the manual - I don't see how to do that without having to maybe take the back of the stove off at the blowers? What does an igniter go for $$$ on the Harmon XXV? Thanks for any help in advance.
