What C on the Refrigerator or Freezer Display (106-prefix) Means
A letter C in either display of a 106-prefix Kenmore refrigerator reports a thermistor failure, and which display shows it tells you which compartment: C in the refrigerator display for the fresh-food thermistor, C in the freezer display for the freezer one.
Common Causes of C on the Refrigerator or Freezer Display (106-prefix)
- A compartment thermistor out of specification
- A thermistor wire harness loose or damaged
- A control board misreading a sound sensor circuit
🔧 One Safe Check You Can Try
Note which display carries the C, because that single detail identifies the part before anyone opens the cabinet.
⚠ Why You Shouldn't Go Further Than That
- Unplug the refrigerator before an interior panel is disturbed; the harness runs back to a live board.
- A thermistor fitted onto a damaged harness reads exactly as badly as the one removed.
- Interior panel access may affect any remaining coverage — check your terms before you start.
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.
