I've replace igniters on my Mt Vernon AE multiple times in the 20 years I've owned it - they just go bad. I had one go the other day, and I replaced it. The new one worked for one night, then a wire came off - I thought that was weird. I replaced it with a second igniter, and now my main circuit is blowing, not the fuse on the power supply but the main panel circuit. Both replacement igniters were third party from a reputable ebay supplier. Is there something I should check before installing a third igniter (OEM) or are there known issues with third party?
