What OC Means
OC means the main control knob and the internal control board aren't communicating correctly.
Common Causes of OC
- Failed control knob assembly
- Damaged or loose wiring to the knob
- Control board fault unrelated to the knob itself
🔧 One Safe Check You Can Try
Power-cycle at the breaker for two minutes to rule out a temporary glitch before assuming a hardware fault.
⚠ Why You Shouldn't Go Further Than That
- Distinguishing a bad knob from a bad board requires testing each independently with the oven de-energized — guessing leads to replacing the wrong part.
- Knob wiring is often integrated with other control functions, and a botched inspection can disable more than just the affected knob.
- A knob reinstalled even slightly misaligned can bind mechanically, creating a new fault on top of the original one.
- Sourcing an exact-match control knob assembly for a specific oven generation is easy to get wrong without a proper parts lookup.
- Control panel disassembly to reach this component typically voids the remaining warranty.
