Viking Fridge Error Code E25: Ice Maker Tray Motor... | appliancefaults.com

Technical Background:

MCU logic and voltage paths.
The E25 error code indicates a fault detected by the main control unit (MCU) related to the ice maker tray motor circuit. The MCU monitors the voltage and current draw of the motor. A fault can be triggered by a shorted motor, an open circuit, or excessive current draw. The voltage path typically originates from the main control board, passes through the wiring harness, and terminates at the ice maker tray motor.

Symptoms:

US homeowner observations.
Homeowners often report the ice maker is not producing ice, or that the ice maker tray appears stuck or frozen. The error code E25 is displayed on the refrigerator's control panel.

Possible Causes:

Faulty ice maker tray motor.
Wiring harness issue between the ice maker and the main control board.
Icemaker control board failure.
Blockage preventing the ice maker tray from rotating.
Low voltage to the ice maker assembly.
Defective main control board (MCU).

Solution:

1

Disconnect power to the Viking refrigerator at the breaker panel.
2

Locate the ice maker assembly. Typically, it's in the freezer compartment, upper left.
3

Inspect the wiring harness connecting the ice maker to the main control board for any visible damage, such as frayed wires or loose connections. Use a multimeter to check for continuity.
4

Remove the ice maker cover and inspect the ice maker tray for any obstructions, such as ice buildup or foreign objects.
5

Using a multimeter, check the voltage to the ice maker tray motor. It should be approximately 120V AC when the ice maker is cycling. Refer to the wiring diagram for specific test points.
6

If the voltage is present and the tray is not rotating, the ice maker tray motor is likely faulty. Replace the ice maker assembly.
7

If the voltage is not present, and the wiring harness is intact, the icemaker control board or main control board may be faulty. Consider replacing the icemaker control board first. If the problem persists, replace the main control board.

Safety Warning:

Always disconnect power to the refrigerator at the breaker panel before performing any repairs. This is a high-voltage appliance. Lock-Out/Tag-Out (LOTO) procedures should be followed to prevent accidental energization during service.

Prevention:

Regularly clean the ice maker assembly to prevent ice buildup. Ensure the freezer temperature is set correctly (around 0°F to 5°F). Periodically check the water filter and replace it as needed to ensure proper water flow to the ice maker.

Expert Tip:

Some Viking models have a service mode that allows you to manually cycle the ice maker. This can help you determine if the motor is functioning at all. Consult the service manual for the specific model for the service mode entry sequence.

Frequently Asked Questions

•How do I access the Viking refrigerator's service mode?

The service mode access varies depending on the Viking refrigerator model. Typically, it involves pressing a specific sequence of buttons on the control panel within a short timeframe. Consult the service manual for your specific model for the correct procedure.

•What is the proper voltage reading I should see at the ice maker tray motor connector?

The voltage reading should be approximately 120V AC when the ice maker is in the fill cycle. Refer to the wiring diagram for your specific model to confirm the correct test points and voltage.

•If the voltage to the ice maker motor is correct, but the tray still doesn't move, is it definitely a bad motor?

Yes, if the proper voltage is present at the motor connector, and the tray is free from obstructions, but the tray does not rotate, then the ice maker tray motor is almost certainly faulty and the ice maker assembly should be replaced.
