Dacor Range, Oven, Cooktop Error Code C01

The C01 code on Dacor Heritage appliances means the control board detected a shorted key condition, where a key or touch input registered as continuously pressed for two minutes without a release being detected. This causes the control to halt normal operation and display the fault code. The issue can originate in the keypad membrane, the ribbon cable, or the control board itself.

The C01 fault itself is a protective response designed to prevent unintended oven operation from a stuck key. Because a shorted key could theoretically trigger or sustain a cooking function without intentional user input, the control flags the fault and limits operation. You should avoid using the appliance until the cause is identified and resolved to ensure safe and predictable control behavior.

Repair costs depend on the root cause. A replacement membrane keypad for a Dacor Heritage appliance typically falls in the range of $80 to $200 for the part alone, while a new control board can range from $150 to $400 or more depending on the model. Adding professional labor generally brings the total repair cost to somewhere between $200 and $600, depending on the technician's rate and which components need replacement.

Some causes of C01 are DIY-accessible. Start by powering off the appliance at the breaker for several minutes and inspecting the control panel for any visibly stuck, sticky, or debris-covered keys. Cleaning around the keypad surface and reseating the ribbon cable connection are reasonable first steps. If the keypad membrane is cracked, peeling, or moisture-damaged, replacing it requires sourcing the correct part and disassembling the control panel, which many experienced DIYers can handle with care.

A power reset by turning off the breaker for a few minutes may temporarily clear the C01 code, but if the underlying cause, such as a stuck key, damaged membrane, or faulty board, is still present, the code will return within two minutes of the shorted key condition resuming. A reset is a useful first diagnostic step but is not a permanent fix on its own.
