Viking Oven Control Knobs Peeling or Turning Black:... | appliancefaults.com

Technical Background:

While the control knobs are not directly related to the MCU logic or voltage paths, their material composition and location near a heat source make them susceptible to degradation over time. The polymer can break down due to excessive heat and the reaction with cleaning agents.

Symptoms:

Homeowners often report that their Viking oven control knobs are becoming sticky, peeling, cracking, or turning black. This degradation can affect the appliance's appearance and potentially create a safety hazard if the knobs become difficult to grip.

Possible Causes:

Exposure to excessive heat from the oven.
Use of harsh or abrasive cleaning chemicals.
Manufacturing defect in the knob material.
Grease buildup attracting particles from the oven.
Prolonged exposure to direct sunlight.

Solution:

1

Turn off the oven and allow it to cool completely. Disconnect power to the oven at the breaker panel.
2

Gently remove the affected control knobs by pulling them straight off the control panel. Some may require a slight wiggle.
3

Inspect the knobs for signs of melting, cracking, or significant peeling. If the damage is extensive, replacement is likely necessary.
4

Clean the control panel surface with a mild detergent and a soft cloth. Avoid abrasive cleaners. Use a plastic scraper to remove stuck on grease.
5

If the knobs are only slightly discolored, try cleaning them with a solution of warm water and mild dish soap. Use a soft brush to gently scrub the surface.
6

Rinse the knobs thoroughly and allow them to air dry completely.
7

If cleaning is unsuccessful or the knobs are severely damaged, order replacement knobs from a Viking appliance parts supplier, ensuring compatibility with your model number. Reinstall the new knobs.

Safety Warning:

Always disconnect power to the oven at the breaker panel before performing any maintenance or repairs. Lock Out / Tag Out (LOTO) procedures should be followed to prevent accidental energization.

Prevention:

Regularly clean the oven control panel with a mild cleaner. Avoid using abrasive cleaners or allowing excessive grease to accumulate. Consider using oven mitts or heat shields when operating the oven at high temperatures to reduce heat exposure to the knobs.

Expert Tip:

Before ordering new knobs, check the part number on the back of an existing knob (if visible). If the oven has a self-clean feature, the extreme heat generated during the cycle may accelerate the degradation of the knobs. Remove the knobs during self-cleaning cycles, if practical. For electronic models, entering the service mode will not address the physical knobs issue. The service mode sequence varies by model number, consult your service manual.
