How to Change an Oven Temperature Probe

Jul 25, 2023, 17:45pm

The temperature probe is an essential part for the proper functioning of the oven. Indeed, it measures the temperature prevailing in the oven then transmits the information to the thermostat (small device located behind the control button) via the power card. Thanks to the probe, the oven will know when the right temperature has been reached and when it should stop heating the oven.

With time and use, the probe may no longer perform its function correctly. Here are the signs that prove that the probe is no longer working:

  • the oven does not heat up;
  • the resistances do not work;
  • no cooking program starts;
  • the oven displays an error code;
  • the oven overheats or underheats;
  • you smell something burning.

If the problem is at this level, the probe must be changed.

The temperature probe is located inside the oven, on the top, close to the ceiling resistance. Its shape and location may change depending on the oven.

The temperature probe in your oven is a key component in maintaining the correct cooking temperature. It senses the internal temperature of the oven and signals the control system to heat or cool as necessary. Over time, this probe may fail or become inaccurate, requiring replacement. This guide will walk you through the general process of changing an oven temperature probe.

How to Change an Oven Temperature Probe

Tools You Might Need

  1. New oven temperature probe (ensure it’s compatible with your oven model)
  2. Screwdriver (usually a Philips)
  3. Needle-nose pliers

Step-by-Step Guide

Step 1: Disconnect the Power

Safety first! Ensure your oven is unplugged and disconnected from the power source. This is an essential step to prevent electrical shock.

Step 2: Access the Oven Interior

Open the oven door to reveal the interior. Depending on your oven model, the temperature probe may be located at the back or the side of the oven.

Step 3: Locate the Temperature Probe

The temperature probe is typically a thin, pronged device sticking out from the oven wall. Once located, you should see one or two screws holding it in place.

Step 4: Remove the Temperature Probe

Using your screwdriver, unscrew the temperature probe from the oven wall. Carefully pull the probe towards you until you can see the wire connections at the back.

Step 5: Disconnect the Old Probe

Note how the wires are connected before you disconnect them. You may want to take a photo for reference. Then, use your needle-nose pliers to disconnect the wires. Be gentle to avoid damaging the connections.

Step 6: Connect the New Probe

Now, grab your new temperature probe. Attach the wires to the new probe, referring to the photo you took earlier to ensure correct placement. Ensure the connections are secure.

Step 7: Secure the New Probe

Once the new probe is connected, gently push the wiring back into the oven wall. Secure the probe in place with the screws you removed earlier.

Step 8: Restore Power and Test

After the new probe is secured, you can plug the oven back into the power source. To test the new probe, set your oven to a specific temperature and use an oven thermometer to check if the oven reaches and maintains that temperature accurately.

In conclusion, changing an oven temperature probe can be a fairly straightforward task if you’re comfortable handling electrical appliances and have a bit of DIY spirit. Always ensure you purchase a replacement probe compatible with your specific oven model, and remember to prioritize safety by unplugging the oven before you start. If you have any doubts or concerns, however, it’s always best to call in a professional to ensure the job is done correctly and safely.
