3 Reasons Why Frigidaire Oven Probe Won’t Turn Off [With Solutions]

One of the best things about modern-day ovens, like Frigidaire ovens, is that they let you measure the temperature of the food inside the oven in real-time.

As a result, you can adjust the temperature of the food while cooking, giving you precisely cooked food.

But sometimes, you might encounter a problem where the Frigidaire oven probe won’t turn off. And you have no idea why the oven display shows food temperature when no food is in the oven?

In this blog post, I’ll explain what an oven probe is, how it works, the possible reasons why it won’t turn off, and how you can fix this problem without any hassle.

Why Frigidaire oven probe won’t turn off?

The Frigidaire oven probe won’t turn off because the metal probe is mistakenly sending signals to the control unit that it is measuring temperature, even though there is no food in the oven. It could be because some food has been left in the oven, malfunctioning the probe or the control unit.

What is an oven probe?

So, before we get into the details of possible problems with an oven probe, let’s first discuss what an oven probe is.

An oven probe is a device that usually comes pre-installed in ovens. The oven probe measures the internal temperature of the food being cooked.

So, when you’re cooking in your oven and see that ‘food temperature’ on the oven display, the oven probe is working at the back end!

So, what does an oven probe consist of? Is it a big component or a small one? Is it mighty complicated or a simple machine?

Usually, an oven probe involves 4 components to perform its functions. These components are as follows:

1. The metal probe
   This part is a small needle-like structure and is present at the far end of the oven probe. The metal probe goes into the food being cooked inside the oven and records the temperature.
   Since the metal probe has to measure high temperatures, it is made of stainless steel or other heat-resistant materials.
2. The cable
   So, when the metal probe records the temperature, where does it send the information? To the control unit of the oven. This is where the cable connected to the metal problem comes into play.
   The cable connects the metal probe to a thermometer or the control unit.
3. The control unit
   The control unit is the third part that forms the functional unit of the oven probe.
   A control unit receives information on food temperature from the metal probe (via the cable). It then displays this information on the oven display in real time.
4. The thermistor
   The last component in the oven probe’s functional organization is the thermistor. A thermistor is a temperature sensor embedded inside a metal probe.
   Thermistor has an electrical resistance that changes with temperature. In plain terms, the thermistor is the actual temperature sensor in the oven probe.

3 reasons why the Frigidaire oven probe does not turn off

Now that we know that the reason the Frigidaire oven keeps on is that the probe mistakenly detects food inside the oven even though you have removed all food from the oven.

As a result, the probe continuously sends temperature measurements to the control unit.

But why does it happen?

There could be 3 possible reasons for it.

1. Leftover food in the oven
   There could be some leftover food in the food, which might still be sticking to the probe.
2. Malfunctioning of the probe
   The thermistor in the probe might have developed an error, and it is overestimating the temperature inside the oven and sending the wrong signals to the control unit.
3. Malfunctioning of the control unit
   In some cases, the culprit is the control unit. No signals come from the probe; the control unit interprets incorrectly and shows you unreal temperatures.

How to diagnose problems with the oven probe?

1. First, ensure that the probe is properly connected to the control unit (or the thermometer). Sometimes, a loose or broken cable is why your oven probe won’t turn off.
2. Second, ensure the problem is free of debris and food particles. Also, please ensure that the probe is not physically damaged.
3. Third, insert the probe into a glass of ice water. This is a standard test. The temperature should read around 32°F (0°C). It could indicate a malfunctioning probe if it reads more (or less) than 32°F (0°C).
4. Fourth, check the settings of your Frigidaire oven. Make sure that the correct probe is selected.

How to fix the Frigidaire oven probe if that does not turn off?

1. Detach the oven from the power supply.
2. Open the oven, locate the metal probe and clean it with white vinegar and a Q-tip. This will clean the metal probe.
3. Let the metal probe dry out, and flip the circuit breaker back on.
4. This should clean debris, oil, or food particles on the metal probe.
5. If the problem persists, better replace the probe.

Conclusion

The Frigidaire oven probe won’t turn on mostly because of some food particles or debris deposited on the metal probe. This can easily be cleaned. If the problem persists, you can order a replacement probe.
