We bought a JB640DRWW to replace our 15-year-old GE JBP75, a very similar model which we were very happy with. Based on online reviews, we opted for this model, but now that it's here, we've come across some design flaws that weren't evident online.
Beeper volume: The oven timer's beep is so soft it can only be heard from the kitchen. This pretty much defeats the purpose of having a timer - I set the timer so I can leave the kitchen and be reminded when it's time to come back and stir the spaghetti sauce. The 15-year-old oven's beeper had a good volume level - not too loud, not too soft.
Oven light: the oven light only comes on when I manually push the button on the control panel. Opening the oven door does not automatically turn on the light. The 15-year-old oven's light - indeed, every other oven light I've ever seen - came on whenever the door was opened.
"Hidden bake element": my mistake here; I thought this oven didn't have the hidden lower bake element. This is a feature I could do without. We're not messy bakers; we only needed to clean the old oven two or three times a year, so ease of cleaning isn't a big selling point. Quick heat-up time, however, is, and with the hidden bake element, it takes a looooooong time to pre-heat the oven. 15-year-old oven? Used to heat up nice and quick.
Control panel: Why buttons instead of a dial? With the oven dial on the 15-year-old oven, it was a quick task to set the oven to 350 degrees, or 425, or even 175 if I just wanted to keep some food warm. With the push-button method, getting to 350 is easy, but setting it to 175 means one press of the "bake" button, then 15 seconds of mashing my thumb down on the "temp minus" button. Tedious!
It's frustrating. All in all, I love the smooth, glass-top stove and the dual-size burner and the ease of cleaning both the cooktop and the oven. It cooks well and I'm hoping it lasts at least as long as its predecessor.
- I recommend this product.
