What C-F0 Means
C-F0 means the main and sub control boards inside a Dacor DOP range have stopped exchanging signals. The 48-inch gas range manual words it as a PCB signal malfunction. Oven functions depend on that link, so they stop.
Common Causes of C-F0
- Power disturbance leaving the boards out of sync
- Harness connector between boards loosened by heat
- Failing sub or main board
🔧 One Safe Check You Can Try
Knobs to Off, then restart. If it persists, cut power to the range at the breaker for 30 seconds or longer and restore it. On a gas range the burners may still light by hand in a power outage; the oven will not.
⚠ Why You Shouldn't Go Further Than That
- Both boards are behind the rear or control panel and share space with the gas manifold.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
