How To Tell If Oven Element Is Broken

Is your oven not heating like it should? You might be wondering how to tell if oven element is broken. It’s a common issue that can stop your cooking plans in their tracks. But don’t worry, diagnosing it is often straightforward. This guide will walk you through the quick troubleshooting steps anyone can do, safely and without needing to be an expert.

We’ll cover the simple visual checks, the easy electrical tests, and what to do next. You’ll know exactly what to look for and how to confirm the problem. Let’s get your oven working again.

An oven’s heating element is the part that gets red-hot and provides the heat for baking and broiling. Most ovens have two: a bake element at the bottom and a broil element at the top. When one fails, your oven’s performance suffers immediately. You might notice uneven cooking, food taking forever to heat, or no heat at all. Identifying a broken element is the first step to a fix.

Common Signs Your Oven Element Might Be Faulty

Before you grab any tools, start with these obvious signs. Your oven often gives clear clues that something is wrong.

No Heat at All: You turn the oven on, set a temperature, but it never gets warm inside. This is a strong indicator.
Uneven Cooking: Your cookies burn on the bottom but are raw on top, or casseroles are cold in the middle. This often points to a failing bake element.
The Element Doesn’t Glow Red: During preheat, peek through the window. The bake element should glow a bright orange-red. If it’s dark or only partially glowing, it’s likely broken.
Visible Damage: Look for blisters, cracks, or holes in the metal tube of the element. Any physical distortion means it needs replacement.
Oven Takes Too Long to Preheat: If preheating takes twice as long as it used too, the element may be weakening.
Tripped Circuit Breaker: A shorted-out element can cause the oven’s circuit breaker to trip repeatedly.

Safety First: Essential Precautions Before You Start

Working with appliances requires caution. Please follow these rules to stay safe.

Unplug the Oven or Turn Off Power: This is the most critical step. Go to your home’s main circuit breaker panel and switch off the circuit that powers your oven. For electric ranges, this is usually a double-pole 40 or 50-amp breaker. If you’re unsure, just unplug the unit from the wall.
Let the Oven Cool Completely: If you were just using it, wait several hours. Elements and interior parts can stay extremely hot.
Use Proper Tools: Have a multimeter for testing. Wear work gloves to protect your hands from sharp edges inside the oven cavity.
Don’t Force Anything: If a screw is stuck or a part won’t budge, don’t use excessive force. You could cause more damage.

Step-by-Step Visual Inspection

This is the easiest place to begin. You don’t need any tools, just your eyes.

1. Accessing the Elements

Open your oven door. The bake element is usually clearly visible at the bottom, covering the floor. The broil element is at the top, often under a panel or shield. For a more thorough look, you may need to remove oven racks.

2. What to Look For

Carefully examine the entire length of the metal tube that makes up the element. Here are the clear signs of failure:

Cracks or Breaks: Any visible split in the metal sheath.
Blisters or Bubbles: Bulging sections on the element’s surface.
Holes or Melting: Obvious gaps or signs that the material has melted.
Discoloration: While some darkening is normal, severe, localized blackening or charring can indicate a hotspot and failure.

If you see any of this damage, the element is definitively broken and needs replacing. Even if it looks okay, it could still have an internal break. That’s where the next test comes in.

How to Test an Oven Element with a Multimeter

A multimeter checks for electrical continuity. This tells you if electricity can flow through the element like it’s supposed to. No continuity means a break inside the element, even if it looks fine.

Gathering Your Tools

You’ll need a digital multimeter, which you can find at any hardware store. You’ll also need a screwdriver, usually a Phillips head, to remove the element or its connections.

Step 1: Disconnect the Power

Reiterate: Ensure the oven is unplugged or the circuit breaker is off. Double-check with the oven’s controls to see if any lights are off. This step cannot be skipped.

Step 2: Locate and Disconnect the Wires

Most elements are held in place by two screws at the back bracket. Once you remove these, you can gently pull the element forward. You will see two wires attached to the element’s terminals, often with spade connectors. Carefully pull these connectors off the terminals. Don’t pull on the wires themselves.

Step 3: Set Up Your Multimeter

Turn your multimeter dial to the lowest setting for resistance (Ohms), often marked with the Ω symbol. Touch the two metal probes together. The display should read close to zero, confirming the meter works.

Step 4: Test for Continuity

Place one probe on each of the element’s metal terminals. Look at the reading.

Good Element: You will get a resistance reading typically between 20 and 100 ohms. A common range is 20-40 ohms. This shows the circuit is complete.
Bad Element: The multimeter will show “OL” (Open Loop) or infinity (a “1” on the left side). This means there’s a break and no continuity. The element is broken.

Step 5: Test for a Ground Fault

This test checks if the broken element is shorting out to the oven’s frame. Set the multimeter to the highest resistance setting. Place one probe on the element’s metal sheath (the tube) and the other probe on one of its terminals. Then test the sheath and the other terminal. The meter should read “OL” or infinity for both. Any other reading indicates a ground fault, which is dangerous and confirms the element needs replacement.

What to Do If the Element is Broken

Once you’ve confirmed the element is faulty, you have a clear path forward.

Finding the Right Replacement Part

Do not just buy any element. You need the exact match for your oven model. The easiest way to find this is to look for the model number of your oven or range. It’s usually located on a sticker inside the door frame, on the back of the control panel, or inside the broiler drawer. Search for this model number online or give it to an appliance parts store. They can provide the correct bake or broil element.

Installation Basics

Replacement is usually the reverse of removal. It’s a simple process:

With power OFF, slide the new element into place.
Reconnect the spade wire connectors to the terminals. They should snap on firmly.
Secure the element bracket with its screws.
Double-check that all connections are tight and nothing is pinched.
Restore power at the circuit breaker or plug the oven back in.

To test your work, turn the oven on to a low temperature (like 350°F) for a few minutes. The new element should begin to glow evenly. If it does, you’ve successfully fixed your oven. If not, you may have a different issue, like a faulty thermostat or wiring problem, which might require a professional.

When the Problem Isn’t the Element

Sometimes, you’ll test the element and it’s fine. If your oven still isn’t heating properly, other components could be at fault. Here’s a brief overview.

Thermal Fuse

Ovens have a safety fuse that blows if the oven overheats. If this fuse is blown, the oven won’t turn on at all. It can be tested for continuity with a multimeter similar to the element.

Temperature Sensor

This is a thin tube, usually at the top back of the oven. It monitors the temperature and tells the control board when to cycle the element on and off. A faulty sensor can cause inaccurate temperatures or prevent heating. Its resistance should change with temperature; you can often find specific testing values for your model.

Bake or Broil Relay

Inside the control panel, these are switches that send power to the elements. If a relay fails, the element won’t get power, even if it’s perfectly good. Diagnosing this usually requires more advanced electrical knowledge.

Control Board

The electronic brain of the oven. If it fails, it may not send the signal to heat. This is often a more expensive repair and typically requires a technician’s diagnosis.

FAQ Section

Can I still use my oven if the element is cracked?

No, you should not use it. A cracked element is a serious safety hazard. It can cause electrical arcing (sparks), pose a shock risk, and potentially start a fire. Stop using the oven immediately until it’s repaired.

How long does an oven element usually last?

With normal use, a quality oven element can last 5 to 10 years. Their lifespan can be shortened by frequent high-heat cooking, spills that cause thermal shock, or general wear and tear.

Why did my oven element burn out?

Common causes include age and normal wear, a sudden spill of liquid on a hot element causing it to crack, a power surge, or a manufacturing defect. Sometimes, it’s just its time.

Can I replace an oven element myself?

Yes, most homeowners can replace an oven element themselves. It’s one of the easiest appliance repairs. As long as you follow safety steps—disconnecting power—and get the correct part, it’s usually a simple job of removing two screws and two wire connectors.

How much does it cost to replace an oven heating element?

The part itself typically costs between $20 and $60, depending on your oven model. If you hire a professional technician, the total cost including labor might range from $150 to $300. Doing it yourself saves a significant amount.

Is it worth replacing an oven element?

Absolutely. Replacing a broken element is almost always worth it compared to buying a new oven. The part is inexpensive, and the repair restores your oven to full function. It’s a cost-effective fix for a common problem.

What if my new oven element isn’t glowing evenly?

A slight variation is normal, but if a section is dark, it could indicate a poor connection at the terminals. Turn off the power and check that the wire connectors are fully seated on the clean terminals. If the problem persists, the element might be defective, though this is rare for new parts.

Final Checklist and Tips
