1. Bake element open (most common)
What it is: Element burns at the back elbow. No glow when bake is called. Ohms open.
Fix: Replace OEM bake element, verify amp draw and full glow.
Typical all-in: $285–$385 all-in
KitchenAid wall ovens (KOSE, KOSC, KOST, KOCE) and slide-in ranges (KFEG, KSEG, KFGG) share the Whirlpool oven platform — same diagnostic order. Five causes cover virtually every no-heat call.

Quick answer
KitchenAid ovens fail to heat in this order: (1) bake element open (no visible glow on preheat), (2) oven temperature sensor drifted (F2 / F3 codes or preheat that never finishes), (3) main control board element relay welded or open, (4) door lock motor stuck after self-clean (blocks bake), (5) convection element failed (convection-bake runs cold while standard bake is fine). Most repairs land $285–$485 all-in. Flat $149 trip fee waived on approval. 1-year warranty.
Root causes, ranked by what we find
What it is: Element burns at the back elbow. No glow when bake is called. Ohms open.
Fix: Replace OEM bake element, verify amp draw and full glow.
Typical all-in: $285–$385 all-in
What it is: Sensor reads out of range. F2 = sensor open / temp high. F3 = shorted. Preheat hangs or oven runs hot/cold.
Fix: Replace OEM sensor, verify 1080 Ω at 70°F, confirm accuracy with thermocouple at 350°F.
Typical all-in: $245–$345 all-in
What it is: Board commands bake but the DPST relay won't close. Voltage check at element terminals during preheat confirms.
Fix: Replace OEM main board (KitchenAid ovens integrate the relays), verify cycle.
Typical all-in: $385–$485 all-in
What it is: Self-clean fatigues the latch motor, which won't release. Board blocks bake as a safety. Often shows F5 or F9 family code.
Fix: Replace OEM latch motor assembly, verify engage / release.
Typical all-in: $285–$385 all-in
What it is: Standard bake fine, convection bake runs cold or uneven — the rear convection element has burned open. Common on KOSE / KOST with heavy convection use.
Fix: Replace OEM convection element, verify cycle.
Typical all-in: $285–$385 all-in
Diagnostic order
Standard bake cold = bake element / sensor / board. Convection cold but standard fine = convection element. Locked door + F-code = latch.
F2 = sensor open / temp high. F3 = sensor short. F5 / F9 = door / latch.
Look for visible break or no glow. Confirm with ohm test.
1080 Ω at 70°F. Off-spec = replace.
If self-clean was just run and door is locked, latch motor is the cause.
FAQs
Most often a burned-open bake element or a drifted oven sensor. If only convection-bake is cold, the convection element has failed. If door is locked after self-clean, latch motor. Repair lands $245–$485 all-in.
F2 = oven temperature sensor open or temperature reading too high. Sensor replacement runs $245–$345 all-in. We always verify with a thermocouple at 350°F before signing off.
The rear convection element has burned open. Standard bake uses the bottom element, so it's still fine. We replace OEM convection element, $285–$385 all-in.
Yes — full built-in wall oven lineup, single, double, and combo (oven + microwave). Built-in installs may add a small trim removal surcharge.
$245–$485 all-in. Bake element $285–$385, sensor $245–$345, convection element $285–$385, latch motor $285–$385, control board $385–$485. The $149 trip fee credits to repair.
Yes — bake elements, broil elements, convection elements, oven sensors, latch motor assemblies, and main control boards for KOSE, KOSC, KOST, KOCE wall ovens and KFEG / KSEG / KFGG slide-in ranges.
