Having an appliance with two ovens is a blessing. You can grill on one and bake on the other while entertaining a significant number of guests. This saves time and ensures every food is cooked correctly. However, though not common, the appliance may breakdown curtail your best efforts to prepare meals within a short period. Ideally, one of the ovens usually breaks down. What happens if the bottom oven breaks down?
Causes of Breakdown in the Bottom Oven
There are many reasons why your bottom oven is not working. However, there are two common reasons why most bottom ovens break down. These are the oven’s power supply and the thermostat or electric oven element.
Typically, a lower heating element in conventional oven fails to work because of an issue with your appliance’s voltage flow, a faulty bake element situated at the bottom of your device, a damaged sensor, a defective control board, and broken fuses. Four of these problems can be dealt with using simple tools and troubleshooting process. These tools include medium Philips screwdriver, a medium common screwdriver, a little screw-holding bowl to contain the screw connectors, and a multimeter. It is also advisable for you to put on gloves as you handle the bake elements considering that it may have coats of burned food and rust.
Troubleshooting a bottom Oven that Isn’t Working
Important: As a homeowner, realizing that you need to waste another Saturday waiting for the landlord or handyman to come over to fix another damaged appliance is frustrating. It shouldn't feel like the norm to constantly have damaged appliances and systems in your home since it can come to a huge cost at the end of each year. Troubleshooting your oven is the first step towards restoring your appliance to its optimum efficiency. It allows you to narrow down the potential issues with your machine to one point of weakness; then, you fix it. Here is how you troubleshoot your oven.
The Home Improvement Solutions eBook covers everything you need to do in your home when it comes to maintenance and improvement so you can avoid wasting another weekend waiting for someone to come to your rescue.
Examining Your Oven’s Bake Element
Your appliance’s baking element is the heat-producing element. It is situated at the bottom of your machine. A lot of electric ovens have both the broil element and the baking element in their bake cycle. The baking element plays ninety percent of the baking role. If your appliance’s baking element is broken, your oven will not attain its required heat limit or not heat at all. It may also take very long to attain the required temperature causing your food to burn on top.
For you to know if the baking element is defective or not, you need to carry out a visual check of your appliance. If your oven’s heating element is separated or blistered, you need to replace it to restore your appliance back to its optimum efficiency. However, if your cooker’s baking element appears normal, turn the appliance on and set it on a bake function for sixty seconds before turning it off. Inspect your appliance’s baking element for heating signs. If it does not have any heating signs, they are likely damaged and need to be replaced.
Testing Your Oven Bake Element Using a Multimeter (view on Amazon)
- Most ovens have a voltage above 200 volts; you need to switch it off before you begin working on it to avoid electrical shock and other life-threatening accidents.
- Search for damaged, corroded or loose wires as you examine your oven’s wiring and terminals of your device’s bake element. To do this, you will have to remove your oven’s back panel to gain access to its wiring and baking elements.
- A simple visual inspection of your oven should reveal damage in your appliance’s wiring and bake element. If it does not, you have to use your multimeter to test the bake element for continuity. Do this by removing your appliance’s element from the primary device. Set your multimeter on Rx1 and touch its probes to your element’s terminals.
- The correct reading of a proper functioning bake element varies depending on the model. However, most bake element multimeter reading should fall in between 19 and 115
- If your appliance’s bake element (view on Amazon) does not show continuity reading or is broken, you need to replace it to restore your oven to its optimum efficiency.
Inspect Your Oven’s Temperature Sensor
The oven temperature sensor is a part, which checks your oven’s temperature and sends signals to your appliance’s electronic control to turn your device’s element on and off, in most modern electronic control ranges. When the temperature sensor does not work as it should, it could cause your oven not to heat or produce very little heat, at the very least. Ideally, your oven’s temperature sensor is situated close to the broil element.
Testing Your Oven Temperature Sensor Using a Multimeter
- Please turn off your oven’s power supply by unplugging it from its wall socket or turning its breaker.
- Search for the temperature sensor inside the oven. It is mostly attached to your oven’s rear wall close to the top. Please remove it from its current location in the oven once you spot it.
- For you to test the temperature sensor, you will have to use your owner’s manual to determine the correct multimeter readings of a properly functioning sensor for your specific oven model.
- Test for continuity using a multimeter set at Rx1, and touch its probes to your ovens terminals. Ensure the temperature sensor is at room temperature to get reliable results
- If your multimeter readings do not measure up to the manufacturer’s recommendation, you should replace the temperature sensor.
Examining Your Oven Control Thermostat
Your appliance’s oven control thermostat controls the broil and bake elements. It is controlled by temperature fluctuations and has contacts that supply power to your oven elements. A faulty control thermostat can lead your oven to produce a lot of heat, less heat, or no heat thoroughly. When your oven is not heating or is receiving less heat, you should check your oven control thermostat to ensure it operates at its optimum efficiency. However, you should check it as the last option.
Testing Your Oven Temperature Sensor Using a Multimeter
- Unplug your appliance from its power source before you start your examination.
- The oven temperature sensor is ideally situated at or near your appliance’s control panel. Once you find it, pull it out from the appliance to test it for continuity.
- Ensure your multimeter is on the Rx1 setting. Touch its probes on the terminals of your oven temperature sensor. The expected readings you should see on your multimeter screen vary depending on the model of your oven. Therefore, you need to check your owner’s manual to determine your oven’s expected resistance. In addition to this, you need to look at the wiring diagram on your owner’s manual to determine the specific set of contacts that you should test for resistance.
- If your multimeter shows different results from your manufacturer’s recommendations, you should replace the oven control thermostat to restore your oven to its optimum efficiency.
Inspect Your Oven’s Fuse
Most ovens with internal fuse could get a blown fuse due to component or wiring fault. When a fuse blows, it indicates a part of the appliance has failed or shorted. Therefore, you will have to fix the problem to restore your oven to normal. A lot of ovens with internal fuses have an internal system that indicates the specific fuse that is causing difficulty in your appliance. You will have to change a blown fuse after inspecting the appliance’s heating element. Do not replace the fuse with a new fuse that has a different rating.
Inspecting Your Fuse for Issues
- Unplug your oven from its power source
- Take note of the fuse that you need to examine. Use your owner’s manual to determine the specific fuse that your need inspected considering that most ovens have multiple fuses
- Remove the fuse from the oven to visually inspect it by looking through the glass window atop the fuse
- Replace the fuse if you determine the fusible link is not as it should
Use this guide to inspect your bottom oven when it does not heat as expected. Consult an appliance specialist when you encounter difficulties beyond your scope.
