I am sorry you are so distraught.
I am just a technician who works during the day and does this when I can. I occasionally find questions when I log on that have been unaddressed. I know when I take the question I will be greeted with a less than nice or less than professional attitude....but I always check to see if they still need help. I could let go like others but the question would not be addressed.
Now as far as your ignitor, and feel free to consider this no charge advice -
If the furnace is near a dryer, lint can be a cause.
If the unit is short cycling...like a dirty filter, dirty sensor...things that make the furnace stop and restart multiple times in one cycle are the usual culprits.
Example - the furnace starts, faults during cycle and restarts.
The ignitor does 4 years work in a month.
Another common issue...the circuit board leaves the ignitor at times instead of turning it off.
I wish you the best. And I am forwarding to customer service.
