Your oven’s bake element is the hardworking component that allows you to cook all your favorite recipes. However, frequent use and environmental factors can potentially cause this critical electric heating coil to burn out prematurely. Understanding the common culprits behind bake element failure is key to avoiding expensive and frustrating replacements down the road. This article explores the most common reasons an oven bake element stops working properly, such as electrical issues, overuse, moisture damage, and manufacturing defects. It also offers helpful tips to prevent burnout and extend the lifespan of this important appliance part.
Electrical Issues
Electrical problems are one of the most common causes of oven bake element burnout. The element relies on a steady flow of electrical current to heat up and operate properly. Any issues with the oven’s power supply can lead to premature failure of the bake element.
Power Surges
Power surges or spikes in voltage are hard on the oven’s electrical components. They can deliver an electrical overload, causing the element to burn out faster. Here are some ways power surges damage the bake element:
- Overheats and weakens the metal wires and components due to the sudden increase in electrical current.
- Causes small cracks or burns in the element, making it more prone to breaking.
- Short circuits are the element that makes it unable to heat properly.
Power surges can occur for various reasons, such as electrical storms, issues with the utility company’s transmission lines, or malfunctions with smart grid technology. Using a whole house or oven-specific surge protector is the best way to protect against surges reaching your appliance.
Faulty Wiring
Problems with the oven’s internal wiring or external electrical connections can also lead to element failure. Some examples include:
- Loose wiring results in fluctuating current flow to the element.
- Old and cracked wire insulation leads to short-circuiting.
- The incorrect wire gauge is unable to handle the electrical load.
- Aluminum wiring which is prone to overheating.
Faulty wiring prevents smooth and steady current flow to the bake element. The irregular power delivery causes the element to strain, resulting in premature burnout. Hiring a professional electrician periodically to inspect the oven’s wiring is recommended. They can check for issues and make fixes before the element fails.
Prevention Tips
- Install whole house or appliance-specific surge protectors. They regulate voltage levels and prevent power spikes from reaching the oven.
- Have an electrician inspect the oven’s wiring connections every 3-5 years or whenever you move to a new home. They can fix loose, cracked, or improperly installed wires.
- Upgrade old aluminum wiring to copper wiring, which handles high electrical loads better.
- If you notice dimming lights or tripped breakers when the oven is on, immediately get the electrical system checked by a professional.
Overuse and Wear
With frequent, high-temperature use over time, oven bake elements eventually wear out. The constant heating and cooling process causes expansion and contraction that fatigues the metal components. Here’s a closer look at how overuse and age contribute to element failure.
High Usage
Oven bake elements are designed for periodic use at normal cooking temperatures like 300-450°F. When you use the oven for extended periods at maximum temperatures above 500°F, it speeds up wear and tear. Some ways high usage degrades the element faster include:
- The cycling between high heat and cool-down weakens the metallic wires and connections.
- Carbon build-up from burnt food can insulate the element, causing hotspots and uneven heating.
- The high heat dries out and cracks the protective insulation around the wires.
Using the self-cleaning cycle also runs the element red hot for hours leading to accelerated deterioration. Try to avoid using the oven at broil or self-clean for more than a few hours at a time to preserve the bake element.
Aging Elements
Like any appliance part, oven bake elements have a natural lifespan. As they age, the components become more brittle and prone to breaking with normal usage. Signs your oven element is aging include:
- Visible cracks or burn marks on the element wires.
- The element takes longer to reach operating temperature.
- Uneven heating or hot/cold spots in the oven.
- Discoloration or thinning of the element wires.
While ovens can last over 10-15 years, most manufacturers recommend replacing bake elements every 5-8 years or so. This can greatly extend the oven’s lifespan.
Prevention Tips
- Avoid using the self-cleaning mode more than a few times per year. It puts a lot of wear on the element.
- Use the oven at lower temp settings like 300-375°F for daily cooking to reduce deterioration.
- Replace the element proactively every 5 years or so based on the manufacturer’s recommendation.
- Give the oven time to completely cool between high-temperature uses to minimize thermal strain.
Improper Cleaning
Using harsh cleaners or scrubbing too aggressively when cleaning your oven can damage the delicate bake element. Over time, improper cleaning can lead to scratches, corrosion, and carbon buildup on the element, causing premature failure.
Harsh Chemicals
Bake elements have protective coatings and insulation that can be degraded by caustic cleaning products. Some problematic chemicals include:
- Oven cleaners with lye or bleach that corrode metal over time.
- Abrasive chemicals like ammonia that wear down coatings.
- Acidic products that react with the metal and dissolve coatings.
Repeated use of harsh oven cleaners leaves the element wires exposed and more prone to burning out. It’s best to use gentle, oven-safe products that don’t contain corrosive chemicals.
Physical Damage
Scrubbing the oven too vigorously can also damage the bake element. Metal scouring pads, sharp scrapers, and rough sponges can scratch the surface of the element. This creates weak spots that are more likely to snap or short circuit.
A layer of burnt food or grease can also build up on the element, insulating it and causing hot spots. Gently loosening and dissolving the debris is better than scraping aggressively.
Prevention Tips
- Use oven-safe cleaning products without lye, bleach, or acid that are specifically designed not to damage interior oven components.
- Avoid using metal pads, sharp tools, or rough scrubbing that can scratch the bake element’s surface.
- Wipe spills as soon as the oven cools to avoid burnt-on debris that is hard to remove.
- Always refer to the oven manual for the manufacturer’s cleaning recommendations.
Moisture and Spills
Liquid spills and excessive humidity in the oven can lead to electrical shorts, corrosion, and mineral buildup on the bake element. This eventually causes burnout.
Liquid Spills
Baked-on food spills are bad enough for oven elements. But spilled liquids like water, oil, and sauces can immediately short circuit or gradually corrode the element wires. Here’s how liquid causes issues:
- Short circuits are the element that makes it heat unevenly or not at all. This strains the wires.
- Leaves behind mineral deposits as the liquid evaporates insulating the element.
- Causes corrosion and oxidation over time, which damages connections.
Even small amounts of liquid that evaporate quickly can leave residues that build up on the element with repeated exposure.
Steam and Humidity
The moisture-laden air from cooking can also degrade the bake element over time. Water vapor condenses on the element and leads to:
- Mineral deposits from water that impede heat transfer.
- Corrosion and pitting as moisture interacts with the metal.
- Insulation degradation from moisture seeping into materials.
Prolonged exposure to steam and humidity accelerates the element’s deterioration. Ensure your kitchen is properly ventilated, and run the oven exhaust fan when cooking.
Prevention Tips
- Immediately wipe any spills in the oven before turning on the element.
- Use a foil tent or oven liner when cooking juicy or moist foods that are prone to bubbling over.
- Ensure your kitchen is ventilated while cooking to release the humid air.
- Run the oven exhaust fan whenever you use the oven, especially for long baking times.
Manufacturing Defects
In some cases, a defective oven bake element can fail right out of the box. Issues in materials, construction, or quality control during manufacturing can lead to premature burnout.
Defective Elements
Some potential manufacturing defects include:
- Inferior metals or wiring materials that can’t withstand high temps.
- Improper wiring connections that loosen over time.
- Cracks or gaps in the insulation and seals.
- Inaccurate coiling or positioning of the element wires.
- Quality control mistakes that miss defects before shipment.
Any flaws or weaknesses in how the element is made leave it prone to early failure once installed and used in the oven.
Warranty and Recalls
If an oven element seems to burn out way sooner than it should, based on its lifespan, manufacturing flaws may be the reason. Check for any recalls on your oven model, and make sure to use the warranty if still valid. Oven makers stand behind their products and will replace elements with manufacturing defects.
Prevention Tips
- Purchase high-quality oven elements from reputable brands known for quality.
- Check online for any recalls on your oven model related to defective elements.
- Register your appliance when you buy it so you’ll be notified of any future recalls.
