Why does my oven thermometer read less than the temperature the oven is set at?
An oven doesn't go to the temp selected. That is the average temp. If you set it to 350, it may drop to 300, then to 400, but will maintain an average of 350. Without knowing your model #, it is hard to say. Some have anticipator (that anticipates the temp and controls the heater and the thermocouple that is trying to keep the temp steady. Some models have an adjustment at the oven switch (rear) that can be adjusted for temp up or down.
