A multi-fuel outdoor pizza oven reaches very high temperatures quickly for Neapolitan-style pizza and roasting. Common wear points are doors/hinges, thermometers, fasteners that corrode outdoors, and (if you use gas accessories) ignition/burner components.
Repair is usually worthwhile for replaceable hardware like thermometers, door parts, or rusted fasteners-especially if the oven body and insulation are intact. Replacement becomes more attractive when the cooking chamber is warped, insulation is compromised, or corrosion is extensive, since heat retention and safety can suffer.
Because these ovens are often seasonal, proper storage matters: keeping it covered and dry can prevent corrosion-related issues. If you use it heavily for entertaining, stable temperature control and quick heat-up are key; persistent heat loss or structural damage may justify replacing.
