Furnace ignitor keeps breaking. Replaced it twice within the last month, for a total of 3 ignitors for one winter. I've been extra careful not to handle the graphite. Furnace was cleaned in the fall and the filters changed whenever they needed it. Goodmand GMPN060-3

Make sure that there is no water dripping off of the heat exchanger onto the ignitor. Reconnect all electrical connections on the circuit board and make sure the ground connections are clean. Test the polarity of the power coming in with a multimeter. Reverse polarity will fry ignitors. Make sure the furnace is on it's own breaker.
