Product review (4 stars): It works now, but for how long?
This the the third spark generator I've put in my Amana range.  They all last a few years, then either quit or become intermittent.  The factory-original module just quit working totally one day.

The next one slowly deteriorated to the point that it worked when the weather was cool and the oven hadn't been on for very long, but wouldn't spark at all if the air temperature here in Southern California got over 105 F or if the oven had been on for an hour or so.  When it cooled off again, everything was fine.

The basic design is apparently a bit marginal or they wouldn't go bad so fast.  I see that this part is used in several different ranges, not just Amana, so I would guess that lots of people have this problem.

What ever happened to the philosophy of spending a few cents more to over-design the product so it gives a lifetime of service?  Apparently that high a standard of reliability doesn't fit in with most corporation's business model for profit maximization.  I'd rate it five stars if they lasted a bit longer.  We'll see how long this one holds up.
