A heating element that stays cold, shows visible damage, or trips the breaker is likely faulty. If you want to know how to tell if heating element is bad in oven, the fastest way is to watch how your oven behaves during preheat. The element should glow red within a few minutes. If it doesn’t, something is wrong.
This guide walks you through every sign of a dead element. You’ll also learn a simple multimeter test that gives you a definite answer.
Common Signs Your Oven Heating Element Has Failed
Most bad elements announce themselves in obvious ways. Others fail quietly and leave you guessing. Here are the signs to watch for.
- The element never glows red, even after 10 minutes of preheating
- Food takes much longer to cook than the recipe says
- The oven won’t reach the temperature you set
- You see blisters, cracks, or burn spots on the element surface
- The element looks warped or has a broken outer sheath
- Your breaker trips every time you turn the oven on
- You notice a burning or metallic smell while baking
One sign alone doesn’t always mean the element is dead. But two or more together point strongly in that direction.
How To Tell If Heating Element Is Bad In Oven
This section covers the two main methods: a visual check and a multimeter test. The visual check takes a minute. The multimeter test takes about fifteen and gives you a final answer.
Method 1: The Visual Inspection
Start simple. Turn the oven on to any bake setting and set the temperature to 350 degrees.
- Wait five to ten minutes.
- Look through the oven window. Do not open the door, since that releases heat.
- Check whether the bottom element glows red.
- Switch to broil and check the top element the same way.
If an element stays dark while the other one glows, the dark one is the problem. If neither glows, you may have a power or control board issue instead.
Also look for physical damage. Small blisters or bubbles on the element surface mean the sheath is failing. A cracked or split element is done. Replace it before it shorts out.
Method 2: The Multimeter Test
This test confirms the diagnosis. You’ll need a multimeter set to measure resistance, which is the ohms setting.
Step 1: Turn Off The Power
Pull the oven’s plug or flip the breaker at your panel. Never skip this step. Heating elements carry high voltage.
Step 2: Access The Element
For a bake element, remove the two screws at the base of the oven cavity. The element pulls forward a few inches. For a broil element, remove the screws holding it to the top of the cavity.
Step 3: Disconnect The Wires
Label the wires with tape if you can. Then pull the wire connectors off the element terminals. They slide off, so no tools are needed.
Step 4: Test The Resistance
- Set your multimeter to the lowest ohms range.
- Touch one probe to each terminal on the element.
- Read the number on the screen.
A healthy element reads between 10 and 50 ohms, depending on the model. Your oven’s manual or a quick search with your model number gives the exact spec.
A reading of zero means a short. A reading of OL or infinity means the element is broken inside. Both results mean you need a new element.
Step 5: Check For A Ground Fault
Touch one probe to a terminal and the other to the metal sheath. You should get no reading. Any reading here means the element is grounding out. That’s the fault that trips breakers.
Other Problems That Mimic A Bad Element
Sometimes the element is fine and something else is broken. Rule these out before you buy a part.
- A tripped breaker or blown fuse cuts power to the oven
- A faulty oven control board stops sending voltage to the element
- A bad temperature sensor makes the oven cycle wrong
- Loose or burnt wire connectors at the element terminals
You can test for voltage at the element terminals with the oven turned on. If you get 240 volts but the element stays cold, the element is bad. If you get no voltage, the problem is upstream.
When To Replace The Element
Replacement is the right call when the element fails the ohm test, shows physical damage, or trips the breaker. Elements are cheap, usually between 20 and 60 dollars. The job takes about 20 minutes with a screwdriver.
Order the part using your oven’s model number. Model numbers sit on a sticker inside the door frame or on the back panel. Aftermarket elements often fit several models, but matching the exact number avoids surprises.
Install the new element by reversing the steps above. Reconnect the wires, secure the screws, and restore power. Then run a test bake at 350 degrees for 15 minutes to confirm it glows.
Safety Tips Before You Start
- Always cut power at the breaker, not just the oven dial
- Let the oven cool completely before touching any part
- Take a photo of the wiring before you disconnect anything
- Never test resistance on a live circuit
- If you smell gas at any point, stop and call a pro
If you are not comfortable working with a multimeter or pulling wires, call an appliance tech. The diagnostic fee is worth it compared to a shock or a damaged control board.
Quick Recap
A cold element, visible blisters, slow baking, or a tripping breaker all point to a failed heating element. Confirm it with a visual check first, then a multimeter test for a definite answer. A good element reads 10 to 50 ohms. A bad one reads zero or infinity, or it grounds out to the sheath. Replace the part, reconnect the wires, and your oven should glow red again on the next preheat.
