Amana Refrigerator / Freezer CI

Amana error code CI indicates: Amana Temp Assure Side-by-Side & Bottom-Mount Refrigerator: Diagnostic code CI indicates ice maker harvest arm motor stalled; ejector blades jammed against ice cubes in mold..

The primary root cause for Amana code CI is: On Amana refrigerators (Amana Temp Assure and Jazz electronic control 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 Refrigerator Temp and Freezer Temp adjustment buttons simultaneously for 3 seconds to reset Jazz board.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Amana code CI persists, the physical component causing On Amana refrigerators (Amana Temp Assure and Jazz electronic control 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.
