Warning signs your oven thermostat is broken
Replacing a thermostat in an oven can be a simple and cost-effective way to ensure safe and efficient cooking. A broken oven thermostat can lead to unevenly cooked or undercooked food, wasted energy, and even dangerous situations like fires. Here are some warning signs that indicate your oven thermostat is broken:
- The temperature inside the oven is not reaching the set temperature on the knob, and the temperature indicator light goes off before reaching the correct temperature.
- The oven is always at maximum temperature, regardless of the setting.
- You do not hear the tell-tale click when turning the control knob.
- Inaccurate temperature readings: The oven displays a different temperature than what is set, or it takes too long to reach the desired temperature.
- The oven thermostat light is not turning on, indicating a possible electrical issue or incorrect temperature detection.
If you notice any of these issues, you can try recalibrating the thermostat or checking the wiring for loose or damaged connections. If the problem persists, you may need to replace the thermostat.
Replacing an oven thermostat can be done by following a step-by-step guide. First, remove the oven door by lifting it off after moving the latches on the hinges to the locked position. Then, access the thermostat by removing the necessary panels and unscrewing any brackets holding the thermostat in place. Detach the capillary wire and tube, and install the new thermostat by reversing these steps, ensuring proper wiring and secure connections.

Removing the oven door
Firstly, open the oven door slightly. Most oven doors have a latch on each hinge. Move these latches into the locked position and gently lift the door off its hinges. You may need to play around with the angle of the door to find the point at which it lifts off easily.
Once the door is off, you will be able to see the thermostat's capillary tube at the top and back of the oven cavity. The next step is to unclip this tube.
After unclipping the tube, the focus shifts to the back panel. If it is held in place by Torx head screws, use a Torx bit at the end of a screwdriver to remove it. Then, take off the top two panels.
With the panels removed, turn the cooker around to access the thermostat control. You should see the capillary wire coming from the top of the cooker into the oven cavity. Pull the capillary tube out of the cavity and remove the fixing bracket that is held in place by screws.
At this point, the oven door, panels, and thermostat will all be removed, giving you access to the thermostat control and the opportunity to replace the thermostat.

Accessing the thermostat
To access the thermostat, you will first need to remove the oven door. Most oven doors have a latch on either hinge that, when moved into the locked position, allows you to close the door and gently lift it off.
With the door removed, you will now need to remove the back panel of the oven. This is typically held in place by Torx head screws, so you can use a Torx bit on the end of a screwdriver to remove them.
Once the back panel is removed, you will be able to see the thermostat's capillary tube, which is usually located at the top and back of the oven cavity. Simply unclip the tube, and then carefully pull it out of the oven cavity.
Next, remove the top two panels of the oven. With these panels removed, you will be able to see the capillary wire coming from the top of the oven into the oven cavity.
Finally, remove the fixing bracket that is held in place by screws, and you will now have successfully accessed the thermostat control!

Replacing the thermostat and capillary
To begin, you will need to remove the oven door. Most oven doors have a latch on either hinge that, when moved into the locked position, allows you to close the door and gently lift it off. With the door removed, you will have access to the thermostat's capillary tube, which is typically located at the top and back of the oven cavity. Simply unclip the tube and set it aside.
Next, remove the back panel of the oven. This may be held in place by Torx head screws, in which case you can use a Torx bit on a screwdriver to remove them. With the back panel removed, you will have access to the capillary wire, which you can carefully pull out of the oven cavity. Now, remove the fixing bracket that is holding the thermostat in place by unscrewing the screws. At this point, you will have successfully removed the old thermostat and capillary assembly.
To install the new thermostat and capillary, simply follow the above steps in reverse. Feed the capillary wire through the back of the oven cavity and secure it with the fixing bracket. Ensure that the capillary tube is properly seated in the oven cavity and clip it into place. Finally, reattach the back panel and oven door. Your oven should now be functioning properly with a new thermostat and capillary assembly.
By following these steps, you can ensure that your oven maintains the desired temperature and cooks your food evenly and efficiently.

Cost of replacement
The cost of replacing an electric oven thermostat can vary depending on several factors. The price of a new thermostat can range from as low as $50 to over $300, depending on the brand and type of oven, as well as the complexity of the installation. Basic oven thermostat replacements for standard electric ovens typically cost around $100, while replacing the thermostat in a high-end, double-oven range can cost upwards of $300.
The labour cost for professional installation can also vary depending on the technician's hourly rate and the time required for the job. Electricians typically charge an hourly rate of $50 to $100, while a gas line specialist may charge $45 to $150 per hour. The complexity of the replacement can also influence labour costs, as some ovens may require more time and effort to access the thermostat. For example, built-in wall ovens may need to be removed from the wall, adding to the overall cost.
It is worth noting that some oven repairs may be covered under warranty, reducing the overall cost of replacement. Additionally, if you are comfortable working with electrical components and following safety precautions, you may be able to replace the thermostat yourself, saving on labour charges. However, if you are uncertain about electrical work, it is always advisable to consult a professional to ensure a safe and accurate installation.
To get a more accurate estimate of the cost to replace your electric oven thermostat, it is recommended to obtain quotes from multiple repair professionals and compare prices.
