KitchenAid Refrigerator Error Code C2
Fridge sensor open
Common Causes
- 1Fridge thermistor failure
- 2Wiring damage
- 3Connector fault
Step-by-Step Troubleshooting
- 1
Find the fresh-food thermistor on the ceiling or upper side wall of the refrigerator compartment, well away from the freezer probe that drives C1
- 2
Disconnect it and read approximately 27,000 ohms at 38F (3C) — noticeably higher than the freezer probe because it is calibrated for warmer air
- 3
A reading of OL or infinite confirms the fresh-food probe has gone open
- 4
Watch the fresh-food/freezer damper: with this sensor open the board parks it wide open and pours freezer air into the fridge
- 5
Trace the fresh-food harness where it passes into the liner and check for a pinch or a moisture-corroded pin
Pro Diagnostic Tip
C2 is the fresh-food thermistor open, the mirror of C1 (the freezer thermistor): the two sensors fail the same way but drive opposite symptoms. An open fresh-food sensor makes the board hold the damper between freezer and fresh food wide open, over-cooling the refrigerator, so on KitchenAid models the giveaway is lettuce and produce freezing in the fresh-food section rather than a warm freezer. Measure ~27,000 ohms at 38F to confirm; an OL reading is the open. The probe mounts on the fresh-food ceiling or side wall, not down in the freezer where C1 lives.
