How do I know if my oven temperature probe is bad?
It’s simple to check your oven’s temperature probe. The resistance between the two prongs on the sensor connection is measured at room temperature. In normal operating conditions, the sensor resistance should be 1080–1090 ohms. That means you’ll need to replace the sensor if the reading is incorrect.
How do you test an oven thermostat?
To test the thermostat, you’ll first need to remove it, then use a multimeter to test it. If you want a quicker and easier, but less accurate test, you can use an oven thermometer to test the temperature of the oven and compare that to the digital readout on the oven itself. Turn off the circuit that powers your oven. Turn off and unplug your oven.

Oven Never Reaches Desired Temperature
If your oven’s temperature sensor isn’t working, it’ll never reach the desired temperature. According to Appliance Board Repair, the sensor can go too high or too low, but it’ll never be at the right setting. This common issue occurs because the sensor thinks it’s reaching the proper setting, even if it’s far off.
Oven Shuts Off Too Early
Some temperature sensors show signs of failure when they shut off before they should. You turn on the oven, the temperature climbs, then suddenly stops. If the oven isn’t at the correct temperature, the sensor likely needs to be repaired or replaced. The sensors are so inexpensive that most people prefer to replace them.
It Never Turns On
While there are countless reasons your oven won’t turn on, one of them is that the temperature sensor is broken. If the sensor is broken, the oven won’t know when it’s time to supply heat. The heating element would stay cold, and you wouldn’t be able to use the appliance. In some cases, the oven will turn on for a moment and then shut off.
The Food Overheats Every Time
While most temperature sensors go out by showing reduced temperatures, some of them go the opposite direction. Setting your oven to 350 degrees Fahrenheit skyrockets the oven to 450 degrees or more. The oven could go to its max setting, causing numerous problems. For example, the food will be overcooked and inedible.
Uneven Cooking and Baking
Den Residence explains a broken temperature sensor often leaves portions of the food uncooked. Much like the aforementioned uncooked core issue, your food will have parts of it that aren’t prepared to eat. The uneven cooking heats part of the oven without providing enough heat for the circulation fan to move around.
Random Oven Temperature Spikes
The sensor does its best to maintain a steady temperature once it reaches the correct setting. When it’s broken or damaged, you’ll notice the temperature goes up and down randomly. These spikes often occur in 10 to 20-degree increments, but they might not go back to the right temperature when they’re done.
The Sensor Is Touching the Oven Wall
A temperature sensor that touches the oven wall is a symptom and a cause. Here’s how this works:
How does an oven temperature sensor work?
The oven temperature sensor is a thermistor which changes resistance depending on ambient temperatures. The sensor is connected to the control by electrical wiring. The control reads the resistance changes in the sensor and reacts, opening and closing electrical relays to switch power to the oven elements on and off.
What color are oven temperature sensors?
Often the temperature sensor wires will be violet colored where they connect to the control but check the particular appliance's wiring diagram to be sure. Install an oven thermometer in the oven and operate the appliance until the problem occurs.
What does a failed oven sensor do?
A failing oven sensor can send misleading readings to the control causing it to behave incorrectly, resulting inaccurate cooking temperatures or fault codes on the electronic control's display. A failed oven sensor is most often responsible for an F3 or F4 error message on the control display.
How many ohms should an oven sensor measure?
The most common oven sensor currently used should measure approximately 1080 ohms when at room temperature. See below for a detailed temperature/resistance chart.
Where is the oven sensor mounted?
Most oven sensors have a mounting plate that is attached to the rear wall of the oven cavity interior. That mounting plate is usually held in place by 2 screws which go through it into the rear oven liner to hold it in place.
Can a sensor be pulled into an oven?
The mounting screws can sometimes be rusted or seized in place so make sure a good screwdriver is used so the screw heads don't get stripped in the process. Once the retaining screws have been removed, the sensor should be able to be pulled (at least slightly) into the oven cavity.
Can you remove the temperature sensor while the oven is hot?
If an error message (or an erroneous temperature display) only occurs during use, it would be dangerous to attempt to remove the sensor for testing while the oven is hot. In this case finding where the sensor circuit wires attach to the electronic control will be necessary to perform testing at that point.
How to tell if oven temperature sensor is bad?
A bad oven temperature sensor can also be pinpointed by checking the resistance at its probe ends. Wait for the oven to be completely cool for this troubleshooting maneuver. Use an ohmmeter to test the sensor probe on both ends. A strong reading should hover around 1,100 ohms.
Where is the oven sensor located?
Take a look inside your deactivated oven. The sensor is usually visible near the back of the space. If the sensor has bent toward the oven's wall, it could be touching hot metal during use.
How to keep tabs on oven temperature?
You may be able to keep tabs on the rising heat by using an independent temperature gauge placed in the oven. Simply set the oven on a low temperature, such as 250-degrees F., and watch the gauge. You will need to replace the sensor as soon as possible otherwise.
What is behind the control panel on an oven?
Behind the oven's control panel is a printed circuit board or PCB. It's designed to last for the life of the appliance, but problems can arise. Component shorts and surges will quickly break the part down. The sensor ends up being your last problem of the day. Oven boards must be in good working order to control any features.
Can an oven temp sensor malfunction?
It's possible that the oven temp sensors malfunctioned. The sensor may be functioning, but it's inaccurate. It's only heating the oven to a fraction of the required temperature. You see the oven's temperature gauge as correct, but the sensor has other plans.
Is a sensor bad?
If you encounter any values below or above 1,100 ohms, the sensor is bad. It uses this resistance in order to warm up the oven to its proper temperature. Swapping out the sensor with a new part should give you the proper resistance needed for reliable operations.
Is an oven a maintenance free appliance?
It roasts, bakes and warms your favorite foods with ease. Today's oven models are full of convenient features that make them practically maintenance-free appliances. However, issues can arise that point to a bad part. Consider the symptoms and solutions to a bad oven temperature sensor.
How many ohms should an oven temperature sensor be?
Connect one lead to each of the terminal of the oven temperature sensor. You should have a reading between 1000-1100 ohms at room temperature. The temperature effects the reading. If it is not in this range replace the sensor.
How to fix a rusted oven?
First disconnect the power before doing any repair work. Look up in the upper portion of the oven for a tube-like metal rod usually about 6" long. It should have 2 screws holding it in. Remove these screws. Note be sure to put a good amount of pressure removing these screws they are often rusted and strip out easily.
