Gozney's Dome pizza oven is typically purchased by enthusiasts for high-heat outdoor cooking and frequent entertaining. Because it's an outdoor appliance exposed to weather, repair vs replace should account for corrosion, burner condition, and safety.
Repairs can make sense if the issue is localized to ignition, thermocouple, or burner components-especially if the oven body and insulation are intact and you can keep it sheltered. Replacement becomes more attractive if the burner assembly is heavily sooted due to airflow issues, if gas fittings or regulators repeatedly fail, or if structural damage (cracks, warped components) affects heat retention.
Also consider usage: very high-frequency firing accelerates wear. Proper cleaning, dry storage, and correct gas pressure are key; if repeated problems persist despite good maintenance, replacement may restore reliability for peak-season cooking.
