Have three issues with range, all are intermittant.

1) Main burner (largest of the four) intermittantly lights with spark.
2) Light on Electronic Control Unit will become dim and then become bright, seems to be no pattern, works great for a couple of days, then goes dim, then bright again.
3) Oven intermittantly will decide not to light but the broiler will. Then on it's own, next time we try, it works great.

Any ideas.

Thank

Thanks for the advise. I just checked the ignitior and no spark, so will order a new ignitor and also the control board. Could the dim light be a power supply going bad or should the control board replacement solve that problem also.

The control board supplies power to the display. The spark from the electrode is supplied from the spark module. Brfore you order a new electrode, try cleaning the old one with a mild wire brush, and make sure the diffuser is free of grease or anything that prevents a good ground for the spark.
