Amana Refrigerator / Freezer H1

Amana error code H1 indicates: Amana Temp Assure Side-by-Side & Bottom-Mount Refrigerator: Diagnostic code H1 indicates critical over-temperature condition in freezer; compartment temperature rose above 0°C..

The primary root cause for Amana code H1 is: On Amana refrigerators (Amana Temp Assure and Jazz electronic control platform): Compressor locked rotor, thermal protector trip, refrigerant leak, or door left open overnight (R600a charge 45–65 g)..

To resolve error code H1: Inspect door closure. Verify if compressor starts: measure winding resistance (6–15 Ω BLDC or 12–25 Ω AC). Check start relay and run capacitor (3–5 µF). Replace compressor if locked. 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 H1 persists, the physical component causing On Amana refrigerators (Amana Temp Assure and Jazz electronic control platform): Compressor locked rotor, thermal protector trip, refrigerant leak, or door left open overnight (R600a charge 45–65 g). 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.
