Product review (2 stars): Poor oven temperature control
I bought this range several years ago and have been unhappy with the purchase. My primary dis-satisfaction is with the oven.
Issues:
- It is extremely slow to pre-heat
- The temperature swings 60 degrees around the set temperature so short cycle baking is very challenging (for example,  cookies can burn very easily).  I used a professional temperature gauge from ThermoWorks (ThermoQ) which tracks High and Low temperatures for a cycle (as defined by the high when the heat cycles off and the low when the heat cycles on). The standard test is to determine the high & low for 3 cycles and average the temperature.  In my case, Setting the temperature at 350, my cycles went between 332.8 degrees and 394.3 degrees which is 61.5 degrees. The cycles are pretty long (10 minutes or longer) so you could be baking your cookies way over temp and each batch is very different depending on where you are in the cycle. While my average based on the 3 cycles was only 364.9 degrees (so the company would probably argue that it is close to set), it is extremely challenging to produce consistent baked goods. It behaves fine for longer cooking roasts, turkeys, etc where the cycle is not as important.

sorry for the long detailed critique but it is a somewhat complicated to state why this oven behaves poorly.
