"I have a JGBP30WEW1WW gas range. A few weeks ago, I turned it on and in about 30 seconds it indicated it was at temp. Knowing this was not true, I put a thermmeter in and waited to see how long it actually took. In About 20 minutes, it stopped heating and was off by over 100 degrees. So we had to do the musical thermostat dance to get it to the right temp. Was trickey with the pies I'll tell ya.
