Viking Oven Error Code 101: Relay Board Hardware Failure... | appliancefaults.com

Technical Background:

error code 101 in a Viking oven typically indicates a failure within the relay control board. This board is responsible for switching power to the heating elements (bake, broil) based on signals from the main control unit (MCU). The MCU sends signals that trigger the relays on the board. These relays are electromechanical switches that complete or break the circuit to the heating elements. If a relay fails, it can disrupt the heating process and trigger the error code. The board typically receives 120V AC to power the relays.

Symptoms:

The homeowner reports that the Viking oven displays error code 101 on the control panel. The oven may not heat up properly, or it may not heat at all. The broiler may also be affected.

Possible Causes:

Failed relay on the relay control board.
Loose wiring connections to the relay board.
Low voltage supply to the relay board.
Overheated relay board components.
Corrupted firmware on the oven's control module.
Short circuit on the bake or broil element circuit.

Solution:

1

Disconnect power to the Viking oven at the breaker panel. Verify the oven is off with a multimeter.
2

Locate the relay control board. It's typically behind the oven control panel.
3

Visually inspect the relay board for any signs of damage, such as burnt components or loose connections.
4

Use a multimeter to check the voltage supply to the relay board. It should be approximately 120V AC. Verify voltage with oven on and calling for heat.
5

Check the continuity of the relays on the board. A faulty relay will show infinite resistance or no continuity.
6

Replace the relay control board if any relays are faulty or if there is visible damage. Use a 1/4-inch nut driver to remove and replace the board.
7

Reconnect power to the oven and test its functionality. Verify error code 101 is cleared.

Safety Warning:

Always disconnect power to the oven at the breaker panel before performing any troubleshooting or repairs. Use proper Lock Out Tag Out (LOTO) procedures to ensure the circuit remains de-energized. The oven contains high voltage components that can cause serious injury or death.

Prevention:

Regularly inspect the oven's wiring connections and ensure they are tight. Avoid overloading the oven with large or heavy items that could put stress on the heating elements and electrical components. Check for proper ventilation around the oven to prevent overheating.

Expert Tip:

After replacing the relay board, perform a self-diagnostic test using the oven's service mode to ensure all components are functioning correctly. The typical sequence is press Bake, then Broil, then Bake again within 5 seconds to enter service mode.

Frequently Asked Questions

•How do I access the Viking oven service mode?

The service mode entry sequence varies by model. Typically, it involves pressing a combination of buttons on the control panel in a specific order, such as Bake, then Broil, then Bake within a short timeframe (e.g., 5 seconds). Consult the service manual for the specific sequence for your Viking oven model.

•What voltage should I expect to see at the relay board?

You should typically see approximately 120V AC at the relay board. This voltage powers the relays that switch the heating elements on and off. Use a multimeter to verify the voltage is present when the oven is calling for heat.

•Where can I purchase a replacement relay board for my Viking oven?

You can purchase replacement relay boards from authorized Viking appliance parts dealers, online appliance parts retailers, or directly from Viking's customer service department. Be sure to have your oven's model number handy to ensure you get the correct replacement part.
