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.

Commercial oven repair costs range from $200 to $2,000+ depending on the issue. Common repairs: igniter replacement $200-$400, thermostat or temperature probe $250-$500, gas valve replacement $350-$700, control board $600-$1,500, heating element (electric) $200-$600. Diagnostic fees of $100-$200 are typically applied to the repair total.

A comprehensive PM program should include: scheduled inspections at manufacturer-recommended intervals, cleaning of condenser coils and filters, calibration of temperature controls, inspection and testing of safety systems, lubrication of moving parts, replacement of wear items (gaskets, filters, belts), refrigerant level checks, combustion analysis for gas equipment, and detailed documentation for each visit. Avoid programs that are just a visual inspection without hands-on service.
