Amana Refrigerator Error Code d1: Ice Maker Tray Sensor... | appliancefaults.com

Technical Background:

The MCU (Microcontroller Unit) on the main control board monitors the ice maker tray thermistor. The thermistor's resistance changes with temperature, providing feedback to the MCU about the tray's condition. The MCU then uses this data to regulate ice production. The d1 error suggests the resistance reading is outside of acceptable parameters or is missing altogether. The voltage to the thermistor circuit is typically 5V DC.

Symptoms:

The homeowner reports the refrigerator is not making ice, and error code d1 is displayed. They may also observe unusual ice formations or a complete lack of ice production.

Possible Causes:

Failed ice maker tray thermistor
Wiring harness damage between the ice maker and main control board
Ice buildup interfering with the sensor
Defective main control board
Loose connection at the ice maker or main control board
Power supply issue to the ice maker

Solution:

1

Disconnect power to the refrigerator at the breaker panel. Verify no voltage is present at the outlet using a multimeter.
2

Locate the ice maker and visually inspect the ice maker tray for ice buildup. Remove any ice obstructing the tray.
3

Disconnect the wiring harness to the ice maker. Inspect the connector and wiring for damage or corrosion.
4

Using a multimeter, measure the resistance of the ice maker tray thermistor. The expected resistance will vary with temperature, but a reading of infinite resistance (open circuit) or zero resistance (short circuit) indicates a faulty thermistor. Consult the service manual for the proper resistance value at a known temperature.
5

If the thermistor appears faulty, replace the ice maker assembly. If the thermistor reading is within range, check the wiring harness continuity from the ice maker to the main control board using your multimeter. Repair any open or shorted wires.
6

Locate the main control board. Check the connection for the ice maker at the board. Ensure it's securely connected.
7

If all wiring and connections are good, the main control board may be faulty and require replacement. Reconnect power to the refrigerator and monitor for error code d1. If the error persists after replacing the ice maker or main control board, there may be another underlying problem.

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Use Lock Out Tag Out (LOTO) procedures to prevent accidental re-energizing of the circuit. Some components may retain a charge even after the power is disconnected. Wear appropriate personal protective equipment (PPE), including safety glasses and gloves. High voltage is present when the unit is powered on. Use caution when working around electrical components.

Prevention:

Periodically inspect and clean the ice maker to prevent ice buildup. Ensure the refrigerator's temperature is properly set (typically around 37 degrees Fahrenheit). Replace the water filter every 6 months, or as recommended by the manufacturer.

Expert Tip:

Some Amana refrigerators have a service mode that can be accessed by pressing and holding specific buttons on the control panel for a set amount of time. Consult the service manual for the exact procedure for your model. Service mode may allow you to run diagnostic tests on the ice maker and other components.

Frequently Asked Questions

•What is the typical resistance range for the ice maker tray thermistor at room temperature (70 degrees Fahrenheit)?

The resistance range for the ice maker tray thermistor at 70 degrees Fahrenheit is typically between 5k and 10k ohms. Refer to the specific service manual for your Amana refrigerator model for the exact value.

•Where can I find the wiring diagram for my Amana refrigerator model?

The wiring diagram is often located inside the refrigerator, either on the back panel or inside the control panel housing. You can also find it in the service manual for your specific model, which can often be found online or purchased from appliance parts suppliers.

•How do I access the main control board in my Amana refrigerator?

The main control board is typically located behind a panel in the back of the refrigerator. You may need to remove screws or clips to access the panel. Before accessing the control board, be sure to disconnect the power to the refrigerator at the breaker panel. Use a 1/4-inch nut driver to remove screws.
