What Are the Symptoms of Bad Oven Temperature Sensor

An oven temperature sensor is a device that alters according to the oven temperature. The sensor is wired electrically to the control. This control reads the changes in the sensor and switches the power to the oven elements on and off. When it’s defective the oven may overheat. What are the symptoms of bad oven temperature sensor? Read on…

 

Differences between the thermostat and sensor

The oven thermostat and how it works can be described simply. The thermostat is an on-off switch that controls the heating element. The sensor and the thermostat work together inside the oven. The sensor is a long, narrow tube normally located at the top and back of the oven.

The thermostat won’t shut off the oven until the heat sensor indicates that the optimum temperature has been reached. You won’t be able to increase the speed of heating. If you suspect the thermostat isn’t working properly it may have to be recalibrated.
This can be done by pre-heating the oven and testing with an oven thermometer. If the temperature difference is more than 10 degrees Celsius the thermostat and the sensor may need replacing.

The signs

When the temperature sensor isn’t working correctly it can:

The explanations

A faulty temperature sensor will cause the oven not to heat to the correct temperature. If food is taking longer to cook, or is undercooked when cooking time is completed this is due to the oven not reaching the desired heat.

You need to make sure that the temperature sensor isn’t touching the interior oven wall. This can affect the accurate measurement of the internal temperature. If this is the case you can reposition it.

The resistance of the sensor should rise with the temperature. You can test that the sensor is working by using an ohmmeter. And then you can get the sensor replaced if it appears to be defective.

When cooking isn’t even some parts of your food may be overcooked. And some may still be raw. This indicates that the internal temperature of the oven isn’t matching the temperature dial setting.

The temperature sensor can be the reason why as it can wear out over time. Use the ohmmeter to test the function. And arrange for a replacement part to be fitted.

Other overheating issues

There are a number of reasons why your oven can overheat and these include faulty:

Understanding symptoms of a faulty oven temperature sensor in detail

Let’s dive deeper into the topic of oven temperature sensors. A faulty oven temperature sensor can lead to various issues that affect cooking performance and safety. Below, we’ll explore in detail the symptoms indicating a malfunctioning temperature sensor and discuss the importance of addressing these issues promptly.

Inaccurate temperature readings on the oven display

The temperature sensor detects the oven’s temperature and sends it to the control panel. If it’s faulty, it might show wrong temperatures. This usually requires the expertise of a qualified technician. Fixing it yourself without proper tools and knowledge can exacerbate the problem.

Oven temperature fluctuates excessively during cooking

A broken sensor can cause the oven to heat inconsistently, leading to uneven cooking. It’s advisable to enlist the help of a skilled technician to replace the sensor, as oven systems are complex.

Food takes longer to cook than usual or doesn’t cook evenly

A faulty sensor can cause uneven heating, making food take longer to cook or cook unevenly. While adjusting cooking times might provide a temporary solution, it’s prudent to have a knowledgeable technician replace the sensor for a lasting fix.

Burnt or undercooked food despite following recommended cooking times and temperatures

If the sensor is faulty, it can make the oven either too hot or not hot enough, resulting in burnt or undercooked food. It’s essential to have a professional repair engineer inspect and replace the sensor rather than attempting a DIY fix.

Error codes appearing on the oven control panel

Modern ovens often show error codes for various issues, including a faulty temperature sensor. It’s advisable to consult a skilled technician to interpret the codes accurately and rectify any underlying problems.

Oven fails to reach the desired temperature or takes an unusually long time to preheat

If the oven struggles to reach the set temperature or takes too long to preheat, the temperature sensor might be faulty. It’s safest to have a professional repair engineer diagnose and replace it due to safety concerns.

Overheating or excessive heat in the oven, potentially leading to scorched or burnt food

A malfunctioning sensor can cause the oven to overheat, resulting in burnt food. It’s crucial to have an oven technician inspect and replace the sensor to prevent further damage.

Unusual odors, such as a burning smell, coming from the oven during operation

Excessive heating due to a faulty sensor can produce strange odors. Consulting a repair engineer is vital to identify the cause and fix it safely.

Visible damage or corrosion on the sensor itself

Physical damage or corrosion on the sensor can affect its accuracy. It’s necessary to have a professional repair engineer replace the sensor to ensure the oven functions correctly.

Complete failure of the oven to turn on or maintain temperature

If the oven doesn’t turn on or struggles to maintain temperature, it could be due to a faulty sensor. Immediate attention from an electric engineer is needed to diagnose and fix the issue safely.

Expert DIY troubleshooting tips for temperature tensor woes

Here are some basic troubleshooting tips for people experiencing problems with their oven temperature sensor:

By following these steps, you may identify and resolve minor issues without professional assistance. However, if problems persist or if unsure, it’s best to seek help from a qualified technician.
