Oven Temperature Sensors Help

Oven temp sensors sense the temperature is the oven cavity and the temp sensor changes resistance, this change in ohm resistance tells the oven control what temperature the oven cavity at and tells the control to shut off the element or turn it back on. The most common temp sensors used today ( *not all ) are approx 1000-1100 ohm resistance at room temperature ( 70 degrees F )

Some ohm readings and their temperature:

Degrees F Resistance
100 1143 ohms
200 1350 ohms
300 1553 ohms
350 1654 ohms
400 1753 ohms
500 1949 ohms

The sensor monitors the oven's internal temperature, ensuring that it accurately reflects the set temperature on the oven's control. By measuring the heat inside the oven, the temperature probe helps in maintaining consistent cooking results, preventing undercooking or overcooking of food.

Over time, the oven temperature probe can fail or become inaccurate due to wear and tear, exposure to extreme temperatures, or damage from cleaning and handling. This can lead to uneven cooking results, with food being overcooked or undercooked, despite setting the oven to the correct temperature.

Symptoms of a bad Oven Temperature Probe include:

  1. Oven not reaching the set temperature
  2. Oven temperature fluctuating more than usual
  3. Food not cooking evenly or within expected time frames
  4. Error codes displayed on the oven indicating a temperature sensor issue
