The 4 Most Critical Wall Oven Parts to Monitor

Wall ovens contain many different parts under the hood. However, there are four components in particular that have the biggest impact on your oven’s ability to cook properly. These parts also tend to wear out over time or fail more frequently than others.
Knowing how to identify issues and replace these essential elements is the key to restoring optimal cooking performance. Here are the four parts to keep an eye on:
The Heating Element
This is the part responsible for generating the heat that actually cooks your food. Electric heating elements are commonly made of metal or ceramic and can reach temperatures upwards of 500 degrees Fahrenheit. They come in both bake and broil varieties.
The baking element is located at the bottom of the oven cavity, while the broil element is in the top area under the interior oven ceiling. These elements receive current from the electrical system and heat up to the desired temperature based on the oven’s thermostat setting.
Over time, with continual heating and cooling cycles, heating elements can burn out, short circuit, or simply lose heating efficiency. Signs your oven’s heating element may need replacing soon include:
- Hot or cold spots in the oven – Food doesn’t bake evenly
- Elements visibly damaged, burned, or broken
- The oven taking longer to preheat
Replacing a faulty heating element is often one of the most common DIY oven repairs. We’ll cover how to select the right replacement later in this guide.
The Temperature Sensor

Also called an oven thermostat or thermistor, this part monitors the internal oven temperature. It provides vital feedback to the oven control board.
The control board then adjusts power to the heating elements to reach and maintain the set oven temperature. If the sensor fails, the oven control board doesn’t receive accurate data.
Symptoms of a faulty oven temperature sensor include:
- Inaccurate oven temperature display
- Oven not reaching set temperature
- Oven overheating or underheating
- Burned or undercooked food
The sensor is typically located along the rear oven wall. To replace it, you’ll need to access the back of the oven.
Interior Oven Light
While not necessarily vital for oven operation, a working interior light makes it much easier to monitor cooking progress without constantly opening the door. The light also automatically turns on when the door is open.
Standard incandescent or halogen bulbs illuminate most oven cavities. Over time, the bulb may burn out or break. Other issues like faulty door switches can cause the light to malfunction. Signs of a problem include:
- Light not turning on at all
- Light flickering or intermittent operation
- Light only works with oven door open
Replacing an oven interior light bulb is generally a quick and simple repair. Just be sure to verify the wattage for your oven model before installing a new bulb.
Igniter

Found in gas wall ovens, the igniter creates the initial spark to light the gas burner tubes. This allows the oven to heat up. The igniter connects to an electrical circuit to receive current.
Repeated heating and cooling causes the igniter to degrade over time. Common symptoms that indicate the igniter needs replacing include:
- Burners not lighting
- Burners lighting but oven not reaching set temp
- Scattered burner flames rather than solid blue jets
Diagnosing and replacing a faulty oven igniter may require more advanced skills. Consult a repair guide for step-by-step instructions.
Now that you know the critical oven components to watch, let’s look at how to select the right replacement parts when repairs are needed.
Choosing the Correct Replacement Wall Oven Parts
Finding and installing the right replacement part is crucial for a successful DIY oven repair. Here are some tips for choosing compatible parts to get your oven back up and running at peak performance:
Verify the Exact Model Number
The model number contains key information to identify parts unique to your specific oven make and model. You’ll typically find the model plate inside the oven door jamb or along the front oven frame.
If it’s worn or missing, check paperwork that came with the original oven. Finding diagrams, parts lists, and instructions for your model online is much easier with this number.
Decide on OEM vs Aftermarket Parts

You’ll generally have a choice between genuine OEM (original equipment manufacturer) parts versus generic aftermarket components. OEM parts are made by the appliance brand and specifically designed for your model.
The advantage is fit and performance, since they are engineered for your oven. However, OEM parts usually cost significantly more than aftermarket equivalents.
Aftermarket parts are made by third parties to function in multiple oven makes and models. They are more affordable but may not fit quite as well. Opt for OEM if budget allows. Otherwise, read reviews to find quality aftermarket parts.
Purchase from Reputable Retailers
Whether shopping online or in local appliance parts stores, be sure to use trusted retailers. This ensures you get authentic OEM parts or decent quality aftermarket components. Check policies on returns just in case you get the wrong part.
We recommend sticking with retailers that specialize in appliance parts and repairs. They are more knowledgeable about proper fit and function.
Factor in Your Skill Level
Some oven repairs like replacing a light bulb or interior door glass involve basic skills easily DIY’ed. More complex fixes like replacing control boards or damaged oven wiring are best left to the pros.
Evaluate your technical comfort and experience level before deciding on a DIY oven part installation. If you need to disassemble much of the oven, the job may require an appliance service technician to ensure safety.
Buy Multiple Parts Upfront
Since you already have the oven disassembled, it makes sense to replace other commonly failing parts at the same time. This prevents having to repeat the repair process later after another part fails.
For example, replace the heating element, temp sensor, and interior light bulb together. Just make sure you adhere to wattage specs when buying replacement bulbs.
Now that you know how to select the right replacement parts, let’s answer some of the most frequently asked questions DIYers have about specific oven components.
Your Top Wall Oven Part Questions Answered
Repairing an appliance yourself for the first time can be daunting. Having a deeper understanding helps ensure success. Here we’ll dig into the details around replacing and maintaining some of the most critical oven parts.
Heating Element FAQs
Let’s start with arguably the most important component – the heating element. Here are answers to some of the most common heating element questions:
What are signs my oven heating element needs replacing?
As covered earlier, uneven cooking temperatures, hot/cold spots, and elements that look burned or damaged indicate a heating element that should be replaced. The oven taking longer to preheat is another red flag.
How long do oven heating elements typically last?
With regular use, expect around 5-10 years of service life from a heating element before needing replacement. Elements in ovens that see daily use may need replacing sooner.
Is it difficult or dangerous for a DIYer to replace a heating element?
Moderate DIY skills are required, as some disassembly is needed to access the element. Main precautions are electrical – heating elements run on 220-240V. Allow the oven to fully cool before replacing to prevent burns.
Overall, it’s generally safer to have an appliance service tech swap out the element unless you’re very comfortable working with household electrical.
Temperature Sensor FAQs
Next up is the crucial oven temperature sensor. Let’s explore some common questions:
What happens if my oven’s temperature sensor fails?
The main symptom is that the oven won’t heat to the set temperature. But it may also overheat if the sensor quits communicating with the control board. Inaccurate temp display is another sign of sensor failure.
