Part: Igniter / hot surface igniter
Temperature sensor or thermostat malfunction
How to Identify: Oven reaches incorrect temperature readings, cooks unevenly, or cycles heat irregularly
Part: Temperature sensor / thermostat
Gas supply or pressure issue
How to Identify: Weak flame, no gas flow to oven burner, multiple gas appliances underperforming
Part: Gas line / regulator / shut-off valve
Clogged burner ports impacting flame quality
