The short answer
On a Dacor 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 that the cooling blower runs when the oven is called, because this platform packs its control above the cavity and depends on that airflow.
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
- A cavity that heats far below the set temperature
- Food cooking on top but not underneath
- 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: Dacor builds this oven as a wall oven with dual-fan convection, 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: Dacor separates the relay board from the touch control, so an oven that displays perfectly and never heats is a relay fault.
- A stalled control cooling blower — Why this rank: The Dacor cooling blower protects the control pocket, and a stalled blower produces heat faults that only appear once the oven is hot.
- The convection element — Why this rank: The Dacor dual-fan convection uses its own elements, so convection can fail while conventional bake still works.
- A failed bake element — Why this rank: The Dacor bake element may be concealed under the cavity floor.
- 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.
- Body: Ranked for a Dacor 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 dacor separates the relay board from the touch control, so an oven that displays perfectly and never heats is a relay fault. Second: hold a hand near the vent above the door with the oven running. With the first check clean, this is what the Dacor platform makes next most likely. Third: run convection and conventional bake from cold and compare. Only after those three is it worth reaching for a failed bake element: it costs more to get at, and it does not explain the first three coming back clean.
Checks you can make
- Call the oven to bake and hold your hand near the vent above the door. No airflow there means the cooling blower is not running and the control above the cavity is being cooked. — 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 convection bake and then conventional bake from cold and note which produces heat. Heat on one and not the other separates the convection elements from the bake circuit. — 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 the oven runs on gas, because burner, igniter and valve work is not an owner repair

What this page omits
This is generalized information: it ranks causes for the Dacor oven range as one platform. It does not cover model-specific variation — a board revision, the system fitted to one production run, or a bulletin covering a single model family. Where a page exists for your specific model, that page is the more specific one and takes precedence over this. Read your model number off the rating plate before ordering any part.
