What C-F7 Means
C-F7 on the DOP30T940IS means the oven’s main board and the cooktop’s main board are not talking. It is the code that links the two halves of the induction range.
Common Causes of C-F7
- Cable between the oven control and the induction cooktop control disturbed
- Cooktop main board failure
- Oven main board failure
🔧 One Safe Check You Can Try
Knobs to Off, restart, and if needed switch the breaker off for 30 seconds or more. Note whether the cooktop zones respond afterwards; that helps the technician.
⚠ Why You Shouldn't Go Further Than That
- The induction cooktop boards sit under the glass top; lifting it without the proper procedure can crack the glass.
