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.

NFPA 96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations) requires cleaning frequency based on cooking volume: monthly for solid fuel cooking (wood, charcoal); quarterly for high-volume cooking (24-hour operations, charbroiling); semi-annually for moderate-volume cooking; and annually for low-volume cooking (pizzerias, churches, seasonal businesses). Your local fire marshal may have additional requirements. Failure to comply can void your fire suppression system coverage.

1) Check if the condenser unit is running. 2) Inspect condenser coils for dirt and debris — blocked coils are a common cause. 3) Ensure walk-in door gaskets are sealing properly. 4) Check if evaporator fan is running. 5) Look for ice buildup on evaporator coils (defrost system failure). If temperature is rising significantly, move temperature-sensitive inventory and call a technician immediately — this is an emergency situation.
