KitchenAid Oven Heating Element Replacement — Bake, Broil & Bow-Tie Convection Elements

KitchenAid ovens may have three heating elements instead of the standard two: a bake element (bottom), a broil element (top), and the Even-Heat bow-tie convection element (rear wall behind the fan). Each operates independently and can fail independently — and identifying which element has failed is the first diagnostic step because the access procedure differs for each.

The bake and broil elements are accessed from inside the oven cavity (remove mounting screws from the rear wall, pull element forward, disconnect terminals from behind). The bow-tie convection element is accessed from behind the oven — remove the rear panel on freestanding ranges, or on wall ovens, slide the oven out from the cabinet first.

Understanding the Three-Element System

Bake element (bottom): A flat looped element at the bottom of the oven cavity. It provides the primary heat source during standard Bake mode. The bake element is the most heavily used element and the most likely to fail first.

Broil element (top): A looped element at the top of the oven cavity, designed for high-intensity radiant heat directed downward. Used during Broil mode and also during preheating on some KitchenAid models (dual-element preheat) to reduce preheat time.

Bow-tie convection element (rear wall): A KitchenAid-specific butterfly/bow-tie shaped element behind the rear wall cover, surrounding the convection fan. It operates only during convection modes (Convect Bake, Convect Roast, Convect Broil). This element heats the air that the fan circulates, and its bow-tie shape distributes heat more evenly than a standard circular ring element.

Detailed Symptoms by Element

Bake Element Failure

Oven does not heat at all in Bake mode: The bake element is open (broken wire inside the sheath). No heat from the bottom of the oven. Broil mode may still work if the broil element is intact.

Visible damage — blistering, dark spots, or a break in the element: Open the oven and inspect the bake element. Look for irregular dark spots (hot spots from internal breakdown), blistering on the element surface, or a visible break or hole where the resistance wire has burned through.

Element glows bright orange/red in one spot: A hot spot indicates the element wire inside the sheath has partially broken, increasing resistance at that point. The remaining wire concentrates all the heat in a small area. The element will fail completely soon — replace proactively.

Sparking or arcing from the element: A ground fault — the resistance wire has contacted the outer sheath. Disconnect power immediately. The element must be replaced; arcing can damage the control board if left running.

Broil Element Failure

No broiling — food does not brown on top: The broil element is not heating. Verify by turning on Broil mode and checking for a red glow from the top element after 2-3 minutes (look through the window, not by opening the door).

Uneven browning during broil: The element has a hot spot or partial failure — one section of the element loop glows while another does not. Replace before complete failure.

Bow-Tie Convection Element Failure

Convection mode heats but unevenly: The bow-tie element has partially failed — one lobe of the butterfly shape has broken while the other remains intact. The fan circulates air but the heat distribution is asymmetric.

Convection does not heat at all but fan runs: The complete bow-tie element has failed. The fan operates normally (you can hear it and feel airflow) but no heat enters the circulated air.

Standard Bake works fine but Convect Bake produces identical results: The bow-tie element provides the additional heat in convection mode. If it has failed, Convect Bake defaults to using only the bake element with the fan — producing minimal improvement over standard Bake.

Step-by-Step Replacement Procedure

Bake or Broil Element Replacement (from inside the oven)

Tools needed: Phillips #2 screwdriver, 1/4-inch nut driver, 5/16-inch or 3/8-inch wrench (for element terminal nuts), multimeter.

Safety: Disconnect power at the breaker (240V circuit). Allow the oven to cool completely.

1. Remove the oven racks for clear access
2. For the bake element: Remove the oven floor panel (if your model has a removable floor) by removing the screws at the rear and lifting out
3. Locate the element mounting screws — typically 2 Phillips or hex screws at the rear wall where the element terminals pass through
4. Remove the mounting screws and gently pull the element forward 3-4 inches to expose the wire terminals behind the rear wall
5. Photograph the wire connections for reference
6. Disconnect the wires from the element terminals — they are typically push-on connectors or wire nuts. On some KitchenAid models, the terminals are secured with small nuts
7. Remove the old element and install the new element by reversing the procedure
8. Ensure the element sits flat against the oven floor (bake) or ceiling (broil) without touching the oven walls
9. Restore power and run a Bake or Broil cycle to verify the new element heats evenly

Bow-Tie Convection Element Replacement (from behind the oven)

1. Pull the range away from the wall or slide the wall oven partially out of the cabinet
2. Remove the rear access panel of the oven
3. Locate the bow-tie element terminals — two wire connections on the rear oven wall, separate from the bake/broil terminals
4. Disconnect the element wires
5. From inside the oven, remove the rear wall cover plate (1-2 screws). The bow-tie element is mounted to the rear wall surrounding the convection fan
6. Remove the element mounting screws (typically 2-3) and carefully remove the element from around the fan
7. Install the new bow-tie element around the fan, secure with mounting screws, reconnect wires from behind
8. Reinstall the rear wall cover inside the oven and the rear access panel

Diagnostic Tips

Resistance test for all three elements: Disconnect power and test each element independently. Normal resistance is 15-30 ohms for each. Open circuit = failed element. Test each element at its terminal connections behind the oven wall.

Ground fault test: Measure between either element terminal and the oven body (any bare metal). Any continuity = ground fault. A ground-faulted element can energize the oven body and must be replaced immediately.

Visual inspection: Turn each mode on (Bake, Broil, Convect Bake) individually and observe through the oven window. Each element should glow a uniform orange-red along its entire length within 2-3 minutes. Dark sections, bright spots, or no glow indicate failure.

Identifying which element mode uses: Standard Bake = bake element only. Broil = broil element only. Convect Bake = bake element + bow-tie element + fan. Convect Roast = all three elements + fan. Knowing which modes work and which do not isolates the failed element.

DIY vs Professional Assessment

Bake and broil element replacement from inside the oven is a straightforward DIY repair — similar difficulty to changing a light fixture. Bow-tie element replacement is more involved because it requires rear access.

DIY recommended if: The bake or broil element has failed (inside access, basic tools). Estimated time: 20-40 minutes per element.

Professional recommended if: The bow-tie element has failed (rear access, wall oven extraction), you are unsure which element has failed (professional testing all three circuits in one visit is efficient), or the element failure was accompanied by arcing or sparking (the wiring and board should be inspected for collateral damage).

FAQ

My KitchenAid oven bakes fine but convection does not work — which element?

Test the bow-tie convection element and the convection fan motor. Both must work for Even-Heat True Convection to function. The bow-tie element is behind the rear wall cover inside the oven, and the fan motor is behind the oven's rear external panel.

Can I replace one element at a time, or should I replace all three?

Replace only the failed element. Elements are independent and fail at different rates depending on usage. The bake element typically fails first (heaviest use), then the broil element, then the bow-tie element. There is no reason to replace a working element preventively.

How long do KitchenAid oven elements last?

Bake elements typically last 5-10 years with moderate use (daily cooking). Broil elements last longer because they are used less frequently. The bow-tie element, despite being a premium component, has similar longevity to the bake element because it operates during every convection cycle.

Is the bow-tie element worth the higher cost compared to a standard ring element?

The bow-tie element is designed specifically for KitchenAid's Even-Heat system. A standard ring element will not fit the mounting points, and even if it could be adapted, the heat distribution pattern would be different. The bow-tie shape is integral to Even-Heat performance.

My oven element sparked and smoked — is the oven safe to use?

No — disconnect power immediately. An arcing element has a ground fault, which can energize the oven body and create a shock hazard. The element must be replaced before using the oven. Also inspect the wiring and board for damage caused by the arcing.
