    Intermittent ignition on gas furnace
    Furnace model GNJ075N12C1.
    Electronic ingition module: SV9500M2682

    Furnace works fine most of the time... then enters the start up mode with no light off and locks out. I have found that if I 'giggle' the ignitor connector in the control module the resistance ignitor comes on, temporary pilot lights, then gas flows and lightoff.

    Woke up this morning with thermostat set for 65. Temp was 60 with noise (no fan air) coming from furnace. Did the 'giggle' and everything works. I've done this before and it works for a few days then happens again.

    How do you change out the igniter. The unit is in the back of the flame tube and I can't see how to disconnect it.
