Amana Refrigerator Error Code 6 Beeps: High Temperature... | appliancefaults.com

Technical Background:

The refrigerator's main control unit (MCU) monitors the temperature sensors within the refrigerator and freezer compartments. If the MCU detects a temperature above a preset threshold for a specific duration, it triggers the six-beep alarm, indicating a high-temperature condition. This system relies on voltage signals from the thermistors that the MCU interprets. Open circuits or out-of-range resistance readings will trigger an error.

Symptoms:

The Amana refrigerator is beeping six times repeatedly. The interior temperature feels warm, and food may be spoiling. The freezer may be functioning normally, or it may also be experiencing temperature issues.

Possible Causes:

Failed or failing evaporator fan motor
Defective defrost heater or defrost thermostat
Faulty temperature sensor or thermistor
Airflow obstruction within the refrigerator compartment
Control board malfunction
Door seal issues

Solution:

1

Unplug the refrigerator or turn off the breaker in the breaker panel.
2

Inspect the evaporator fan motor for proper operation. Listen for unusual noises or lack of fan movement. Use a multimeter to check for continuity.
3

Examine the defrost heater and defrost thermostat. The heater should show continuity. The thermostat should be closed when cold.
4

Check the temperature sensor (thermistor) resistance using a multimeter. Compare the reading to the manufacturer's specifications for the current refrigerator temperature. Replace if out of range.
5

Clear any obstructions that may be blocking airflow, such as food items or ice buildup.
6

Inspect door seals for damage or gaps that could be letting warm air in. Replace if necessary.
7

If the above steps don't resolve the issue, the control board may be defective. Replacement may be required. Consider licensed technician assistance.

Safety Warning:

Always disconnect power to the refrigerator before performing any repairs. Use proper lockout/tagout (LOTO) procedures. Be aware of potentially high voltage present in the control panel area. Wear safety glasses.

Prevention:

Regularly clean the refrigerator coils located at the back or bottom of the unit with a vacuum cleaner. Ensure proper airflow by not overfilling the refrigerator and freezer compartments. Replace the water filter every six months.

Expert Tip:

Some Amana models have a diagnostic mode accessible through a specific button sequence (consult the service manual). This mode can display real-time temperature readings and error codes, aiding in pinpointing the problem. Try holding the door switch down and pressing the temperature down button 3 times within 6 seconds to enter service mode on some models. This may vary per exact model.

Frequently Asked Questions

•Where is the evaporator fan motor located in my Amana refrigerator?

The evaporator fan motor is typically located inside the freezer compartment, behind the rear panel. You'll need to remove the panel to access it.

•How do I test the defrost heater for continuity?

Use a multimeter set to the ohms setting. Disconnect the defrost heater from the wiring harness. Place the multimeter probes on the heater terminals. A reading other than infinite resistance (open circuit) indicates continuity.

•Where can I find the temperature sensor resistance chart for my Amana refrigerator model?

The temperature sensor resistance chart can usually be found in the service manual for your specific Amana refrigerator model. You may be able to find it online or contact Amana directly for assistance.
