When you turn on your oven, every model will first run a pre-heat cycle that will allow it to reach the appropriate temperature before it turns to try to maintain that temperature. This is crucial for items such as baked goods that need to be baked at very exact temperatures right from when they go in the oven. However, if your oven becomes stuck on the pre-heat cycle it means that something is wrong.
Failed Heat Sources
Gas ovens use igniters to produce heat while electric ovens use a heating element. If one of the ignitors is not working or if one of the heating elements is broken in an electric oven, then your appliance will not be able to reach the temperature you set it to. A pre-heat cycle should take, at most, 30 minutes. If it is going on any longer or stays stuck in the cycle, then a failure of a heating element may not be allowing it to reach the temperature quickly or at all.
Faulty Thermostat Sensor
The temperature probe found inside the oven that communicates the temperature to the oven control board can fail as well. If it is not functioning, the oven may never come off a pre-heat cycle as it cannot detect the correct temperature. These probes can be checked for a specific ohm resistance of around 1100 ohms at room temperature. If the probe is way off this amount, it needs to be replaced.
