Grates up and the cooktop opened to get at the burners

Case Study · BlueStar Range Repair · Woodinville, WA
One burner on this 36-inch BlueStar range gave no spark, and the owner smelled gas from the oven during bake, so they stopped using it until it was checked. We found a failed spark module and a weak bake igniter drawing only 2.8 amps, too little to open the oven gas valve reliably. We replaced both and tested every burner and the oven. Real photos from the job below.
What happened
The problem
One of the six open burners on this BlueStar RNB366BSS gave no spark and wouldn’t light. The owner also smelled gas from the oven during bake, even with the flame lit, and had stopped using the oven until it could be checked.
What we found
The spark module for that burner had failed. In the oven, the bake igniter still glowed, but the clamp meter showed it drawing only 2.8 amps. That current is what opens the oven gas valve, and at 2.8 A it wasn’t enough to open it reliably, so the bake burner was slow to light. We leak-checked the oven gas valve and found no leak. The smell came from that delayed ignition.
The fix
We replaced the spark module and the bake igniter, then tested all six surface burners and the bake function. The range lights normally again, and the repair carries our 90-day warranty.

On ovens with a glow igniter, the gas valve opens only once the igniter draws enough current. A weak igniter opens it late, so gas can build up before the burner lights. On this BlueStar the igniter drew only 2.8 A. We leak-checked the oven gas valve, found no leak, and replaced the igniter. If a gas smell is strong or doesn’t go away, turn the oven off, leave the house and call your gas utility from outside.
With a clamp meter on the igniter circuit while it’s glowing. An igniter can glow and still be too weak to open the gas valve, so the current reading matters more than the glow. The old igniter on this BlueStar read 2.8 A, not enough to open the valve reliably.
Usually clogged burner ports, a faulty igniter, or a spark module issue. On this BlueStar RNB366BSS the spark module had failed, so the burner got no spark at all. We replaced it and tested all six burners.
