Viking Oven Heating Element Cracked or Blistered:... | appliancefaults.com

Technical Background:

The oven's MCU (Main Control Unit) sends a signal to a relay, which then provides 240V AC to the heating element. The element's resistance converts electrical energy into heat. A cracked or blistered element indicates compromised resistance and potential short circuits.

Symptoms:

The US homeowner observes visible cracks or blisters on the Viking oven's heating element. The oven may not heat evenly, or may not heat at all. There might also be sparking or burning smells.

Possible Causes:

Overheating due to thermostat malfunction
Age and normal wear and tear
Manufacturing defect in the element material
Power surges causing element stress
Excessive self-cleaning cycles at high temperatures
Improper system of the heating element

Solution:

1

Disconnect power to the oven at the breaker panel (LOTO - Lock Out Tag Out).
2

Remove the oven racks and any obstructions.
3

Locate the heating element terminals, usually at the rear of the oven cavity. Note wire positions before disconnecting.
4

Using a 1/4-inch nut driver or appropriate screwdriver, disconnect the wires from the heating element terminals.
5

Use a multimeter to check the element's resistance. A significantly high or infinite resistance indicates a failed element.
6

Install the new heating element, ensuring the wires are reconnected to the correct terminals.
7

Restore power at the breaker panel and test the oven's heating function.

Safety Warning:

Always disconnect power at the breaker panel before working on electrical components. High voltage is present when the oven is powered on. Lock Out Tag Out (LOTO) procedures must be followed.

Prevention:

Avoid using the self-cleaning cycle excessively. Ensure proper ventilation around the oven. Schedule annual licensed technician inspections.

Expert Tip:

Many Viking ovens have a hidden service mode accessible through a specific button sequence (refer to the service manual). This mode allows you to test individual components, including the heating element relay.

Frequently Asked Questions

•What is the proper resistance range for a typical Viking oven heating element?

Typically, a Viking oven heating element should read between 15 and 30 ohms. Refer to the specific service manual for your model for precise values.

•How can I test the oven's thermostat to ensure it's not causing overheating?

Use a multimeter to check the thermostat's continuity at various temperatures. Also, confirm that the oven temperature matches the thermostat setting using an oven thermometer. If there's a significant discrepancy, the thermostat may be faulty.

•Where can I find a replacement heating element for my Viking oven?

Contact a Viking authorized parts dealer or appliance parts supplier. Have your oven's model number readily available to ensure you get the correct replacement part.
