furnace ignitor not working all the time

I have a coleman DGAT056BDC 1995? . It has electronic ignition, the ignitor works sometimes. It worked all night then just quits, a few minutes to hours it will glow and light and run like it should, it will do this alot. I replaced ignition module, I have inspected ignitor looks good, flame sensor & cleaned with steel wool, when it doesn't light it runs the gas valve quick then disengages. I have got 24v before it disengages. Any ideas?

Can I test the ignitor with my vm, what resistance should it be?

Hi,

Test ignitor leads for 120vac with a call for heat whenever the ignitor should be energized.


Thanks,
