Viking Oven Error Code 80: Control System Software... | appliancefaults.com

Technical Background:

error code 80 on a Viking oven typically indicates a software or communication error within the electronic control system. The Main Control Unit (MCU) relies on programmed logic and stable voltage paths to operate correctly. A voltage interruption or corrupted software can trigger this error.

Symptoms:

The homeowner reports the Viking oven displays error code 80 on the control panel. The oven may not heat, or the display may freeze. The buttons may be unresponsive.

Possible Causes:

Corrupted main control board software.
Communication failure between control boards.
Power surge or voltage spike.
Loose wiring harness connection to the main control board.
Faulty temperature sensor data affecting control logic.
Defective EEPROM chip on the control board.

Solution:

1

Disconnect power to the Viking oven at the breaker panel. Wait 5 minutes.
2

Check the wiring harness connections to the main control board for looseness or damage. Use a 1/4-inch nut driver to tighten any loose connections.
3

Inspect the ribbon cable connecting the display board to the main control board. Ensure it's properly seated.
4

Verify the incoming voltage to the oven is 120V AC using a multimeter.
5

If connections are good and voltage is correct, attempt a hard reset of the oven by disconnecting power for 15 minutes.
6

If the error persists, replace the main control board. Order the correct replacement part number.
7

After replacing the control board, verify proper oven operation through a bake cycle and self-clean cycle.

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker before servicing. High voltage is present when the oven is powered. Wear appropriate personal protective equipment (PPE).

Prevention:

Use a surge protector on the oven's power outlet to prevent damage from power surges. Schedule annual licensed technician inspections to check wiring and connections.

Expert Tip:

Viking ovens sometimes have a service mode. Consult the service manual for your specific model to access diagnostics and error logs. The access sequence often involves pressing and holding a specific combination of buttons while powering on the unit.

Frequently Asked Questions

•Where is the main control board located in my Viking oven model?

The main control board is typically located behind the control panel or in the back of the oven cavity. Consult the service manual for your specific model.

•How do I know if the temperature sensor is faulty and causing the error?

Check the sensor's resistance using a multimeter. Compare the reading to the specifications in the service manual at room temperature (70°F). An out-of-range reading indicates a faulty sensor.

•What is the correct replacement part number for the main control board?

The correct replacement part number depends on your specific Viking oven model. Locate the model number inside the oven door or on the back panel and consult a parts distributor or the Viking website to find the correct part.
