Whirlpool Refrigerator / Freezer CI

Whirlpool error code CI indicates: Whirlpool 6th Sense Dual-Cool & Total NoFrost Refrigerator: Diagnostic code CI indicates ice maker harvest arm motor stalled; ejector blades jammed against ice cubes in mold..

The primary root cause for Whirlpool code CI is: On Whirlpool refrigerators (Whirlpool 6th Sense algorithms and WAVE / L1373 electronic platform): Ice bridge formation over ejector rake, stripped plastic drive gears, or open harvest motor coil (3.5–5.0 kΩ, 230V AC)..

To resolve error code CI: Disconnect power. Clear stuck ice cubes with warm water. Test harvest motor coil resistance (3.5–5.0 kΩ). Check optical beam sensor. Replace ice maker if drive gear is stripped. Press and hold the Filter Reset or Alarm Silence touch pad for 5 seconds until the confirmation chime sounds.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Whirlpool code CI persists, the physical component causing On Whirlpool refrigerators (Whirlpool 6th Sense algorithms and WAVE / L1373 electronic platform): Ice bridge formation over ejector rake, stripped plastic drive gears, or open harvest motor coil (3.5–5.0 kΩ, 230V AC). must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
