During the Holiday season appliance usage is in high demand for Ranges, Ovens, and Dishwashers.
Check your oven temperature. Purchase an oven thermometer, and preheat the oven for at least 30 minutes. Then record the highest and lowest temperatures for three cycles. If you have an oven that has a low temperature of 325˚ and a high of 375˚ when the dial is set at 350˚, then your oven is working properly.
If the calibration is off by 25 degrees or more, you may have an oven control, thermostat or sensor problem, requiring replacement parts: Range-Stove-Oven-Parts
