Amana Refrigerator / Freezer ER dS

Amana error code ER DS indicates: Amana Temp Assure Side-by-Side & Bottom-Mount Refrigerator: Diagnostic code ER dS indicates defrost NTC thermistor open or short circuit; defrost cycle duration strictly time-limited..

The primary root cause for Amana code ER DS is: On Amana refrigerators (Amana Temp Assure and Jazz electronic control platform): Water penetration into sensor epoxy head, wire corrosion, or internal resistor failure (2.7 kΩ at 25°C, 15.0 kΩ at -10°C)..

To resolve error code ER DS: Disconnect power. Measure resistance across sensor wires: nominal 15.0 kΩ at -10°C. If sensor reads infinite Ω or < 1.0 kΩ while frosted, replace NTC sensor capsule. 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 ER DS persists, the physical component causing On Amana refrigerators (Amana Temp Assure and Jazz electronic control platform): Water penetration into sensor epoxy head, wire corrosion, or internal resistor failure (2.7 kΩ at 25°C, 15.0 kΩ at -10°C). must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

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.
