Dacor Oven Error Code C01

Touch panel shorted key

Dacor codesDacor oven codes

Touch panel shorted key - a key release is not seen for two minutes, indicating a stuck key on the glass front or failed electrical circuit.

First step from the service manual

Wipe front of glass to verify all items/food are removed. If functionality resumes, continue as normal. Otherwise, replace glass/touchpad assembly.

What C01 means on a Dacor oven

The C01 error code on a Dacor oven indicates a shorted key condition on the touch panel. Specifically, the control board detects that a key on the glass touchpad has remained in a pressed state for two continuous minutes without registering a release signal. The control interprets this sustained input as an electrical fault rather than intentional use, triggering the error to prevent unintended operation or runaway commands.

The touch panel on Dacor ovens consists of a glass front surface bonded to a capacitive or membrane-based electrical circuit. When a key is pressed, it completes a circuit that the control board reads as a momentary input. If that circuit stays closed, whether from physical pressure, contamination, or a failed internal connection, the board flags the condition as a stuck key. The two-minute threshold is built in to distinguish a prolonged press from a genuine electrical fault.

The most common cause of this error is something on the glass surface holding a key area in contact, such as food residue, grease buildup, a utensil resting against the panel, or pooled liquid. If cleaning the glass surface does not resolve the code, the fault lies within the touchpad assembly itself, where an internal circuit has shorted or the membrane layer has failed. In that scenario, the entire glass and touchpad assembly requires replacement, as the circuit components are not individually serviceable.

Common causes of C01

  1. 01

    Food or grease on the glass surface

    Wiring / connection

    Residue or liquid on the touchpad glass can bridge a key contact area and simulate a continuous press. Thoroughly wiping the panel with a clean, dry cloth often resolves this immediately.

  2. 02

    Object resting against the control panel

    Wiring / connection

    A utensil, pot, towel, or other item pressing against the glass can hold a key in a triggered state. Remove anything near the panel and check if the error clears.

  3. 03

    Liquid infiltration into the touchpad assembly

    Part replacement

    Water or cleaning solution that has seeped behind the glass can short the internal circuit, keeping a key signal active even when the surface appears clean. This typically requires touchpad replacement.

  4. 04

    Failed internal touchpad circuit

    Part replacement

    The membrane or capacitive layer inside the touchpad assembly can fail due to age, heat cycles, or wear, causing a key position to read as permanently closed. Replacement of the glass and touchpad assembly is required.

  5. 05

    Damaged glass front with cracked or deformed surface

    Part replacement

    Physical damage to the glass panel can deform the underlying circuit, creating a persistent contact at one key location. Inspect the glass for cracks or chips, and replace the assembly if damage is found.

Frequently asked questions about C01

What does C01 mean on a Dacor oven?
The C01 code means the oven's control board detected a key on the touch panel that remained pressed for two continuous minutes without releasing. This is called a shorted key condition. It can be caused by something physically on the glass surface or by a failed electrical circuit inside the touchpad assembly. Cleaning the glass is the first step to diagnose whether it is a surface issue or an internal fault.
How do I fix the C01 error on my Dacor oven?
Start by wiping the entire glass front of the touchpad to remove any food, grease, or liquid. Also check that no objects are resting against the panel. If the error clears after cleaning, normal operation can resume. If the code persists after the glass is clean and clear, the glass and touchpad assembly will need to be replaced.
Will resetting my Dacor oven clear the C01 error?
Powering the oven off at the breaker or unplugging it will temporarily clear the code, but if the underlying cause is still present, the error will return within two minutes of the oven detecting the stuck key again. A reset is only a lasting fix if the original cause, such as debris on the glass, has been removed before power is restored.
Is it safe to use my Dacor oven when the C01 code is displayed?
The C01 code indicates the control panel is not responding normally, which means the oven may not accept commands reliably or may behave unpredictably. It is best to avoid operating the oven until the fault is resolved. If the oven is currently on and you cannot control it, shut it off at the circuit breaker as a precaution.
How much does it cost to fix a C01 error on a Dacor oven?
If the issue is just surface contamination on the glass, there is no parts cost involved. If the touchpad and glass assembly requires replacement, parts and labor costs can range from roughly 150 dollars to 400 dollars or more depending on the specific model and local labor rates. Getting a quote from a qualified appliance technician before proceeding is recommended.
