What C-F7 means

C-F7 on the Dacor DOP30T940IS induction range tells you that the main board in the oven section and the main board for the cooktop have lost their communication. Each board controls its own half of the range, and they depend on a steady exchange of signals. When that exchange stops, the display shows C-F7 and the range may refuse to follow commands from the controls. The code is about the link between oven and cooktop, so we start there.

Common causes of C-F7

  • The cable or connector joining the oven board to the cooktop board
  • The communication circuit on the oven main board
  • The communication circuit on the cooktop main board
  • A momentary power disturbance that a restart clears
✓ One safe check you can try

1. Turn the mode knob to Off and start the range again. 2. If the code is still there, disconnect power at the breaker for at least 30 seconds, then reconnect it. 3. Should C-F7 appear again after that, leave the range off and call us. Do not open the cooktop or the control area yourself.

! Why to stop there
  • Restarting tells us whether the link recovers, but not which end of the link, the cable, the oven board or the cooktop board, is responsible.
  • We check the cable and connections between the oven and the cooktop before we look at either board.
  • Call us or fill out the online form to schedule service, and we give you a written price before work starts.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

C-F7C-F7 questions
Why does my Dacor induction range show C-F7?

The oven main board and the cooktop main board are not exchanging signals. On the DOP30T940IS that stops the range from following its controls normally, so the display shows C-F7 until the connection is back.

Does C-F7 mean the cooktop itself is broken?

Not by itself. The code reports lost communication between two boards, which could be a cable, a connector or a board. We test the link before deciding what, if anything, needs to be replaced.

What should I do before you arrive?

Turn the mode knob to Off and restart. If the code stays, switch the range off at the breaker for at least 30 seconds and restore power. If it persists, leave the range unused until we check it.
