Product review (1 stars): Serious Oven Users:  AVOID THIS RANGE!
This range has decent, but not high-end features.  I would have given it 4-5 stars except for what I consider a fatal flaw with the oven, as described below.

The first thing I cooked in the oven was a pork tenderloin with a pop-up timer.  At the time listed on the package, the pop-up hadn't popped.  15 minutes later, it hadn't popped.  At 20 minutes, I cut into the tenderloin to see if it looked done.  It did, so I pulled it out.  But that, and reading another review suggesting that the oven temperature wasn't accurate caused me to buy a good oven thermometer and run some tests.

A small part of the problem is that the oven consistently read 25 degrees higher than the temperature on the thermometer.  A nice feature of the range is that you can adjust the oven up or down up to 35 degrees using the menu.  But that by no means solved the problem.

Here's a test done after I recalibrated the oven temperature.

Set the oven to 400 degrees.  PRE (for pre-heat) appears on the screen.

In 8 minutes, the oven pre-heats to 275 degrees and beeps.  PRE changes to the set temperature, 400 degrees.

By 12 minutes, the oven has pre-heated to 350 degrees and the bottom element goes off.

At 20 minutes, the oven is finally at 400 degrees.  That's when you can put whatever you're baking in the oven and have the baking time be meaningful.  The oven seems to hold the set temperature well once it has been reached.

And that explains why the tenderloin timer didn't pop up when it was supposed to.

GE's helpline said that the unit probably needed a tech to do a re-calibration beyond what a user could do.  They scheduled a tech to visit me.  The tech called a special GE hotline for techs.  They told him that that was normal behavior for this unit.  The premature announcement of completed pre-heating was a "feature" to prevent the outside of meat from being over-seared.  The slow actual pre-heating is an "energy-saving feature."  Despite what the hotline said, the circuit board in this range can't be adjusted.

I had trouble believing that all this was true, but a different tech I talked to by accident confirmed it.  I don't mind so much the time it takes to pre-heat, but GE should devise a way to announce that pre-heating is complete only when it actually is.

In the meantime, I'd strongly recommend that any purchasers also get a good quality oven timer and use that to determine when to put anything into the oven if they want baking directions to be at all meaningful.
