How to Replace the Lower Bake Element on an LG Oven

The lower bake element in LG electric ovens provides the primary heat source during standard Bake mode. On LG ProBake Convection models, the lower element works alongside the rear-mounted ProBake element during combined heating cycles, but it remains the sole heat source for standard (non-convection) baking. When this element burns out, the oven will not heat in Bake mode, though Broil (upper element) and Convection (rear element) may still function. A burned-out bake element is often visible as a spot where the metal sheath has bubbled, blistered, or shows a clear break.

This guide covers lower bake element replacement on LG freestanding ranges, slide-in ranges, and wall ovens with standard calrod-style hidden or exposed bake elements. The element connects to the oven wiring through two screw terminals at the rear wall of the oven cavity.

Before You Start

• Tools needed: Phillips #2 screwdriver, 1/4-inch nut driver, multimeter, work gloves
• Parts needed: LG bake element for your model (~$30-$65)
• Time required: 20-30 minutes
• Difficulty: Intermediate
• Safety warning: Disconnect the range from the 240V outlet or turn off the circuit breaker. Verify power is off with a non-contact voltage tester. Allow the oven to cool completely before working inside the cavity. The element terminals carry 240V during operation.

Step-by-Step Instructions

Step 1: Confirm the Bake Element Has Failed

Set the oven to Bake at 350 degrees F. If equipped, use LG ThinQ Smart Diagnosis to check for element error codes. Visually inspect the lower element (look through the oven window or open the door after a few minutes). A working element glows red-orange uniformly. If no glow appears and the oven does not heat in Bake, the element has likely failed. Alternatively, test with multimeter: disconnect power, access element terminals from rear panel, measure resistance (expect 20-50 ohms for healthy element, OL for failed).

Step 2: Remove Oven Racks and Bottom Panel

Remove all oven racks. On LG models with a removable bottom panel (covering a hidden bake element), remove the 2-4 screws at the rear of the bottom panel and slide it forward and out. On models with an exposed element visible on the oven floor, the element mounts directly to the rear wall with two screws and rests on support brackets.

Step 3: Remove the Element Mounting Screws

Locate the two screws securing the bake element to the rear oven wall (Phillips or 1/4-inch hex head). Remove both screws. The element will now be loose inside the oven cavity. Gently pull the element forward about 3-4 inches to expose the wire terminals at the rear wall. Do not pull aggressively as the wires have limited length.

Step 4: Disconnect the Wire Terminals

With the element pulled forward, you can see two wire connectors attached to the element terminal posts at the rear wall. These are typically spade connectors or screw-on wire nuts. For spade connectors, grip the metal connector with pliers and pull straight off each terminal post. For screw terminals, unscrew the wire nut or terminal screw and free the wire. Note which wire goes to which terminal (though bake elements are non-polarized, consistency helps).

Step 5: Remove the Old Element

With both wires disconnected, pull the old element fully out through the rear wall hole. The element passes through a grommet or opening in the rear oven wall. If it catches on the grommet, gently wiggle while pulling. Inspect the old element for the failure point: you should see a blister, break, or hole in the metal sheath where the internal resistance wire burned through.

Step 6: Install the New Element

Feed the terminal posts of the new element through the rear wall opening from inside the oven. Push until the element base plate sits flush against the inside of the rear wall. The terminal posts should protrude through the wall on the back side. From inside the oven, verify the element rests in the same position as the original (flat against the floor or supported by brackets).

Step 7: Reconnect Wires and Secure

Reconnect the wire terminals to the element posts. Push spade connectors firmly onto the posts until fully seated. Reinstall the two mounting screws to secure the element to the rear wall. Verify the element does not contact the oven floor, walls, or the bottom panel when reinstalled. A touching element will create a hot spot that can damage the oven interior.

Step 8: Reassemble and Test

Reinstall the bottom panel if your model has one. Replace oven racks. Restore power. Set oven to Bake at 350 degrees F. The element should glow evenly within 3-5 minutes. Monitor for any smoke or odor from the new element (normal manufacturing oil burn-off on first use). Verify oven reaches set temperature within 15-20 minutes. On ProBake models, also test Convection Bake to verify both the lower and rear elements activate together.

Troubleshooting Common Issues

• If the new element does not heat, recheck wire connections. A loose spade connector is the most common installation error. Also verify the oven selector is set to Bake (not Broil or Convection only)
• If the element glows unevenly (one leg brighter than the other), this is normal during initial heating as the legs warm at slightly different rates. If one leg never glows, the element may be defective
• If the oven trips the circuit breaker when the element activates, a short exists. Check that no wires are pinched behind the rear wall and that the element terminals are not contacting the metal oven frame
• If the oven heats but temperature is inaccurate after element replacement, the temperature sensor may need recalibration. LG ovens allow temperature offset adjustment through the control panel
• On ProBake models, if standard Bake works but Convection Bake does not heat fully, the ProBake rear element may have a separate failure unrelated to the lower element replacement

When to Call a Professional

• If the wires behind the rear wall show heat damage or the terminal grommet is melted, professional wiring repair is needed before a new element will function safely
• If the oven cavity shows damage from the old element failure (burn mark on the floor, damaged liner), cosmetic repair may be desired though it does not affect function
• If the control board is not sending power to the element position despite correct Bake mode selection, board diagnosis is needed

FAQ

Q: How do I know if the lower bake element or temperature sensor is the problem? A: If the element does not glow at all during Bake mode but Broil works (upper element glows), the bake element has failed. If the element glows but temperature is inaccurate, the temperature sensor is the likely cause. Test the element with multimeter: 20-50 ohms is healthy, OL means failed.

Q: Does replacing the bake element affect my LG ProBake Convection performance? A: The lower bake element is used during standard Bake mode and as supplemental heat during some ProBake cycles. Replacing it with the correct OEM or compatible element restores all designed heating modes. The ProBake rear element is separate and unaffected.

Q: Can I use an aftermarket element on my LG oven? A: Yes, if the physical dimensions, terminal spacing, wattage, and voltage match the original. Many aftermarket elements are manufactured to OEM specifications at lower cost. Verify the element shape matches your oven cavity configuration.

Q: How long do LG oven bake elements typically last? A: 5-15 years depending on usage frequency and self-clean cycle use. Self-clean cycles at 900+ degrees F stress elements significantly. Heavy self-clean users may see shorter element life. Standard baking at 300-450 degrees F causes minimal stress.
