I'm going with the regular iPhone 6 because I already carry an iPad mini Retina for document storage and study so I don't need the plus size phone. And putting a tablet up to your head to make a phone call is just so wrong on so many levels.
Excessive sparking is usually a grounding problem with the spark circuit. The most common culprit is carbon and gookus buildup under the burners, interrupting good grounding with the oven chassis. Remove the burner base and clean both it and the cooktop surface it rests on with a wire brush and / or scotch brite pad.
I was galled, liked dried refuse on a toilet bowl, when I read the ignorant impertanance in DrewT's reply to Brother Fairbanks' most benificent and sage reply, loaded with practical insight.
Brother Fairbank's reply was his signature gracious, knowledgable, and factual style to a neophyte in the craft or a DIYer.
DrewT, if you took any insult from Brother Fairbanks' thoughtful reply, then the problem lies with your own twisted ego, always looking for an insult, rather than in anything Brother Fairbanks said or implied.
The proper reply to Brother Fairbanks then would have been to say, "Thank you, Master, for taking the time to help me."
The proper reply now would be to say, "Forgive me, Master, for I knoweth not what I say."
I love these units because they're so easy to work on and it pays well. Remove the grates and burner caps. Unscrew the brass burner rings-- it helps to push down on the top panel a little as you do this because it removes the tension off the rings and they turn easier. As you lift out each burner base, disconnect the wire to the electrode. Keep everything in order on a separate surface. With the burner bases removed and the wires disconnected, you can remove the entire top panel. The ERC is right there in front and the relay board is below another compartment, couple of screws to remove the cover and access it. Make sure you don't get the spark wires mixed up or you'll have a continuous sparking problem when you re-apply power.
