Signs your oven needs calibration: food is consistently undercooked or overcooked at standard settings, cooking times are significantly longer or shorter than expected, the displayed temperature doesn't match an independent thermometer reading. Oven calibration should be part of every service visit and can drift over time from component wear. A variance of more than 25°F warrants professional calibration.

Combi oven steam issues are commonly caused by: clogged steam generator or boiler scale buildup, failed heating element in the steam generator, water inlet valve problems, or steam nozzle blockages. Mineral scale from hard water is the most common culprit and can be prevented with regular descaling. A combi oven specialist should inspect the steam system as improper repairs can damage the boiler.

Common causes include: faulty igniter or ignition module, failed heating element (electric ovens), thermostat or temperature probe failure, gas valve issues, or clogged burner ports. Start by checking error codes on the control panel if equipped. If the oven lights but doesn't reach temperature, the thermostat or temperature probe is often the culprit. A certified technician can diagnose the root cause quickly.
