The short answer
On a KitchenAid oven, an oven that runs without producing heat usually comes down to the relay board that switches the elements rather than anything deeper in the machine: where the elements are switched by relays, the relay fails long before the element does. That puts it on the service side of the line, but start here anyway — it costs nothing and it decides which repair is being quoted for: check whether the cooling blower runs when the oven is called, because KitchenAid parks the control above the cavity and relies on that blower to keep it alive.
What you are seeing
- A display that counts a preheat that never completes
- An element that never glows
- Heat on broil but nothing on bake
- Not this fault: An oven that heats but bakes unevenly, which is a calibration or convection problem
- Not this fault: A cooktop that works with a dead oven, which narrows it to the oven circuit
- Body: KitchenAid builds this oven as an even-heat true convection cavity with a dedicated third element behind the fan, a relay board separate from the glass-touch control and a cooling blower over the control pocket. That architecture decides which of these you see first.
- Also check note: If these fit better, the fault is a different one.
Likely causes, in order
- The relay board that switches the elements — Why this rank: KitchenAid separates the relay board from the touch control, so an oven that displays normally but never heats is a relay fault rather than a display fault.
- A stalled control cooling blower — Why this rank: The KitchenAid cooling blower protects the control pocket above the cavity, and a stalled blower cooks the control into intermittent faults.
- A failed bake element — Why this rank: The KitchenAid bake element is under the floor on some models and is not visible without lifting a cover.
- The broil element — Why this rank: Heat on broil but not on bake tells you the control half is working and puts the fault in the bake circuit.
- The convection element — Why this rank: The KitchenAid third element behind the fan fails on its own, so convection bakes badly while conventional bake is normal.
- Body: Ranked for a KitchenAid oven specifically.
What to check, in order
- Body: The order follows the ranking, and the ranking follows the platform. First: confirm the element itself is sound first. It goes first because kitchenAid separates the relay board from the touch control, so an oven that displays normally but never heats is a relay fault rather than a display fault. Second: hold a hand near the vent above the door with the oven running. With the first check clean, this is what the KitchenAid platform makes next most likely. Third: with the power off, run a light along the element looking for a break or a blister. Only after those three is it worth reaching for the broil element: it costs more to get at, and it does not explain the first three coming back clean.
Checks you can make
- Set the oven to bake and stand at the control panel. A cooling blower that never starts, or one that runs rough, is what turns a working control into an intermittent one. — Tools: none — Time: about ten minutes
- With the power off at the breaker and the appliance cold, run a flashlight along the whole length of the element looking for a break, a blister or a bright pitted section. — Tools: flashlight — Time: about ten minutes
- Run a convection bake and then a conventional bake with the oven cold each time and note which produces heat. Heat on one but not the other separates the third element from the bake element. — Tools: oven thermometer — Time: about forty minutes
- Set the oven to broil from cold and watch the upper element. Heat on broil but not on bake proves the control, the door switch and the supply, and puts the fault in the bake circuit. — Tools: none — Time: about ten minutes
- Body: Stop at the first step that would need a meter on live terminals or a sealed assembly opened.
Before you open anything
Safety
Let the cavity cool completely and switch the appliance off at its breaker before anything is opened. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Let the oven cool fully. A cavity and its elements hold heat long after the display has gone dark.
When to call
The line is not difficulty, it is what the next step costs and risks. Call when: the element is confirmed sound and the oven still never heats

What this page omits
This is generalized information: it ranks causes for the KitchenAid oven range as one platform, not for a single model. Where a page exists for your specific model it is the more specific one and takes precedence over this. The narrower pages below cover the other presentations of this symptom.
