Amana Refrigerator Error Code E3

Error code E3 on Amana refrigerators indicates a temperature sensor malfunction or communication failure within the refrigerator's cooling control system. This error typically means the appliance cannot accurately read the internal temperature, which prevents it from maintaining proper cooling cycles.

Common Symptoms

• Refrigerator compressor runs continuously or cycles irregularly • Interior temperature becomes warmer than the set point • Freezer section may frost over excessively or not freeze properly • Error code E3 displays on the digital display panel • Ice maker may stop producing ice • Fan noise may become louder or more frequent • Food may spoil faster than normal

Possible Causes

• Faulty refrigerator temperature sensor (thermistor) in the cooling compartment • Loose or corroded electrical connector on the temperature sensor • Damaged wiring between the sensor and control board • Failed evaporator fan that prevents proper temperature distribution • Control board malfunction preventing sensor signal processing • Water or frost buildup on the sensor preventing accurate readings • Failed defrost cycle due to sensor failure • Blocked air damper between freezer and refrigerator sections

Safety Checks You Can Do

• Unplug the refrigerator from the 120V outlet for 60 seconds, then plug it back in to reset the control board • Verify the refrigerator is plugged securely into a working outlet and check that the home circuit breaker has not tripped • Confirm the refrigerator and freezer doors are closing completely with no gaps in the door seals • Inspect the door gaskets for cracks, tears, or excessive wear that could allow warm air to enter • Ensure the vents inside the refrigerator and freezer compartments are not blocked by food or containers • Check that the temperature settings are appropriate (typically 35-38°F for refrigerator, 0°F for freezer) • If equipped with an ice maker, verify the water supply line is connected and the inlet valve shutoff is in the ON position • Remove and inspect any accessible air filters or water filters, replacing them if they appear clogged or dirty • Clean the condenser coils at the back or bottom of the refrigerator to ensure proper airflow • Verify that the refrigerator is level and not tilted, which can affect internal air circulation
