I have been researching how to diagnose this intermittent lighting issue with my furnace but the common issues do not seem to apply.
- Blower turns on
- Ignition coil turns cherry red
- Sound of gas blower starts
- No ignition, ignition coil dims, and blower remains on
I've uploaded a video as well: https://youtu.be/Y9umhFh6_gc
I am trying to figure out a strategy for determining what part I may need to order and replace.
