Viking Gas Oven: not igniting until high temperature

Professional Repair Guide

What is this symptom?

Experiencing delayed ignition in your Viking gas oven? If the burner or bake burner only ignites after an extended delay or reaching a high internal temperature, this can be frustrating. This symptom indicates a problem with the igniter or gas supply, leading to inefficient cooking. Understanding the underlying causes can help you troubleshoot and restore your oven's performance.

Important Tips for Viking Models

Viking support documentation and technicians note delayed ignition is often linked to weak igniters degrading over time on Viking gas ovens.

User Suggested Solutions

Inspect and replace the igniter if it's not glowing or is damaged. To do this, turn off the gas supply, remove the oven bottom panel, and test the igniter with a multimeter. If faulty, replace it with a new one.
Clean the burner ports with a soft brush or compressed air to remove any debris or buildup. Ensure the gas flow is unobstructed by testing the flame after cleaning.
Check the thermostat calibration. Use an oven thermometer to compare the actual temperature with the set temperature. If the thermostat is faulty, replace it according to the manufacturer's instructions.
